IoT & Connectivity

Hi,   I was able to successfully set up EMS and LSR on the same device (raspberry pi) and send data to Thingsworx. However, when I tried to set up EMS and LSR on two different devices, I am not able to bind/connect the device running LSR to the device running EMS. I have attached the screenshot of the config.json,config.lua and error received while running wsems and LuaScriptResource for reference. Kindly appreciate your assistance.    Note: In the given screenshots 192.168.137.151 is the ip address of the device running EMS and 192 168.137.150 is the ip address of the device running LSR.   Thanks. Vijay 

When you create a model in thingworx, is there a way to see how long it will take to run? I know, the more data, the longer it will typically take. But, I get a running window and it could last 60 seconds or 60 hours. I have no idea. How can I see this information?

Hello ,         I have added generic radio buttton on Thingworx 9.0 version, after click on generic radio button  can I visible label or text field widget ??

1) Could anyone let me know the working/use of Asset Advisor, and 2) How does it get the data? Is it Kepware or some other option?   Thanks in advance.

Hi Experts,   I have upgraded on Mashup manually from TWx Ver 8.4.5 to Ver 8.4.11. I found the Generic Radio Button Widget is removed in TWx Version 8.4.11, and hence I have to achieve the similar functionality using simple Radio Button Widget available there, with help of available State definitions.  I put same Group name for all buttons but not getting any hint how I could use previously defined State Definitions to work similar like old Generic Radio button Widget.   Requesting your valuable suggestions. Attached screenshot for your reference here.

Hello all,   i want to have a Thing that implements a ThingTemplate and various ThingShapes with exclusive permissions, i.e. a "ProjectAdmin_ThingShape" that provides services only available to users within the "ProjectAdmin" Group, a "ProjectSupervisor_ThingShape" with services only available to members within the "ProjectSupervisor" Group etc.   When i set the permissions, users with access to the implementing thing were still able to execute any services from the implemented ThingShapes.   Is this desired behaviour or did i miss something? I need cascaded permissions, so the thing is already instantiated on another permission restriction and if i had to instantiate the things for each of the groups mentioned above, the complexity multiplies.   The access "should not" be possible on a mashup level anyways, but for security reasons i want this properly modeled with the Thingworx permissions framework.   Thanks for your help.

Dear Developers,   I am trying to use the method in the subject, but I am unable to. Checking the documentation, this is the signature: public void UpdateDataTableEntry(TagCollection tags, Location location, java.lang.String source, java.lang.String sourceType, InfoTable values) throws java.lang.Exception And all the fields besides tags and values are optional. I am wondering what optional does mean in this case (null value?) as this is the only signature available. I have built the values like this, as an example:   InfoTable values = new InfoTable();ValueCollection row = new ValueCollection(); row.SetIntegerValue("id", id); values.addRow(row);   and I am not sure about what is the purpose of the tags in this case.   Thank you!

Is is possible to generate a multi line message for the status message widget. Looking to display a number of status messages i.e. error 1 error 2   I have tried inserting the new line character (\n) but the widget still draws on a single line. If I output the same text to a text area widget it does display on multiple lines   Thanks in advance K  

I have a menu linked to 3 mashups. Within a mashup, I have a boolean property that gets triggered when a certain value is hit. I currently have this turn red within the mashup but is there a way to get my menu item to turn red if the user is not currently looking at this mashup? For example, on the image below, can I get the Data3 menu item to flash red or turn red when this boolean property is triggered? And if so, how?

Dear community,   I would like to perform the activity I have written in the subject, and by looking at the documentation it looks doable. However, I have some issues: I have created a DataShape and a DataTable in the composer, and exported them via the "Export" option. I have then imported them in Eclipse (Right click on Extension Project -> Import -> ThingWorx -> Entities and the .xml files are imported correctly in the project. After this, I am not sure on how to proceed, since the import option does not cause the creation of the corresponding Java classes, or the entries in the metadata.xml file. By following tutorials/documentation, custom services should be created in the .java class of the related entity. Should I perform those manually, and then map them to the entities I created?  I hope my question is clear, but feel free to ask for more details. Federico

Hi, there!   Documentation only shows a partial list of available entity types and also a partial list of the available characteristic collection types. Where can I find the full list of both, available entity types and available characteristic collection types?   Regards, Nahuel

Hi all,   I need to know the execution history along with input parameters of a service in thingworx. Can you please help me.   Thanks and Regards,

Hi team, I am using value display in thingworx 9.0 which is used to show uploaded image on the mashup.  When I choose the image by using a file upload widget, the image is shown on the value display but when I hover a mouse cursor on the image it will display error like a tooltip, I don't know how to remove this error. Please check the below picture the error shown in green color.   Please suggest me how to remove this error.

Hi, I am new to Thingworx and developing an application to upgrade the firmware remotely in the connected devices. Is it possible to use Thingworx REST APIs to do it?      Thanks in Advance Sree 

Hello everyone,   I am trying to import an extension, and I keep getting the error I wrote down in the Subject:   "Entity Import Not Supported for File Type: .zip"     this happens with any extension, also the one build in this tutorial. The only thing I have done differently is the Gradle build, which I carried out via Command Prompt, but the error shows up also if I use the pre-built .zip file in the tutorial files.   I am using a 30-day cloud trial now, so I wonder if this could be a limitation of the trial.   Thanks and best regards!    

Hello,   I'm currently having trouble with my custom authenticator: each time a user logs through it, a new session is created. My user reach my thingworx server (8.4.0-b2013) with REST call. All the process of the authentication works fine but a new session is created with each request.  After some investigation, I think only having the cookie served by thingworx across tomcat allows to find the active session. However I don't use the cookie as it would bypass my custom process of authentication.   It seems x-thingworx-session equals to true or false doesn't change anything  Maybe there is a way to find the active session without cookie   I know I could limit the maximum number of session per user in configuration, but my goal is to use data stored in the session, so even if I limit the number, a new session would be created and I will lose data already stored   Any ideas?

If my mashup builder starts to get cluttered with services / params / etc., I like to use the bindings UI to pick sources for my service params.  However, I noticed that there is no way to source User Extensions or Session Parameters on that UI.  Am I missing that somewhere?

Hi everyone,   I'd like to change the chart bar width, but I dind't find any property to do it.   I think it's possible by CSS code, but I don't have knowledge abou it.   Can anyone help me?   Follow the image below:     Regards,   Leonardo

Dear experts,   I am getting the error message you find in the subject while calling APIs under /Thingworx/Resources/EntityServices, while I have no issue for /Thingworx/Things. Checking previous posts I have seen that this looks like a common error when visibility rights are missing, but I am not sure of what the minimum requirements are (i.e., if it's enough to assign rights at the APIKey level, or if you need to create an Organization and/or UserGroup).   Thanks and best regards!

Hi,   i have a Master Mashup and want to pass parameters to the Mashup which is using my Master. So i set the State in my Master to, for example "Running", then my Mashup should update content accordingly. I just need the value i set on my Master Mashup somehow in the other Mashups that are using it.   Is this possibly via Mashup Properties? Or how can i do this?Url Params came to my mind, but arent the best solution, because it is just a filter.   Cheers Pat

Hello,   One of our thingworx instance database(postgresql is being used as default persistance provider) is corrupted so, I have taken the pg_dump of whole db and then created new database and restored old pg_dump to new one and then i have updated the platform-settings.json accordingly. After these changes, application is working fine but i have observed that 'id' field (entry_id which will do auto increment internally) is not getting updated for new entries in stream and value_stream tables.   Can someone please provide the inputs to handle this. Did anyone faced this kind of issue?   -thanks,Abhiram

Hi Community,   We were working on Custom UI development and trying to create custom extension for Thingworx Mashup as widgets. I have checked many old Article on community for Extension development using Angular-Thingworx. But not found any detailed Extension Developer Guide for new versions of Thingworx.    Found this but associated link on attached document not working and its was for old version. https://community.ptc.com/t5/IoT-Tech-Tips/Integrating-AngularJS-with-ThingWorx/m-p/534655   Please suggest latest developer guide for Extensions development.   Regards, Mayank

I'm using a gridadvanced widget populated by a service that returns an infotable, this works fine. After data is loaded into the grid, I make a popup appear when the user double clicks a row in the grid, passing the service's SelectedRows as a parameter to this popup. My grid is currently set to Single row selection.   However, the SelectedRows of the service mentioned above never changes, and its SelectedRowsChanged event is never triggered.   Using Thingworx 8.5.4
