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, 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?

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

Hello,   I'd like to ask you, what is the best approach to achieve "High availability" for KepServerEx using ThingWorx.   My current solution: I created two things based on industrial Gateway template, each of them is connected to one KepServerEx. Both KepServerEx have exactly same channels and same connections to physical PLCs.   In each of these Industrial Gateway things I created subscription for DataChange event for isConnected property and when it is false I programatically change IndstrurialThing property on connected Remote things.   Do you think it is a good approach? Or is there better solution to achieve "HA" for KepServerEx?

Can we make in some way that any particular user can login on application but cannot login on ThingWorx Composer? If yes , then how?   Thanks in advance.  

I've been using the Font Awesome widget, but it only works for v4 icons.  I'm not familiar enough with widget programming to update the widget.  Also, I don't see the Font Awesome widget in the marketplace anymore.   Or, is there a way of incorporating Font Awesome icons without the widget?

When I view my mashup, for some reason my line chart disappears whenever my values update. The line chart is supposed to update values but it is static. Not sure why. But, the main issue, is it disappears from view completely after a few updates. 

For what purpose the above functionality used? Is it for hiding the code at composer level? If not, how can we hide code of any service and providing the leverage of only executing the service at composer level?   Please advise on both use-cases i.e. the use of allow override and process of hiding the code of any service for a thing/template/shape.   Thanks in advance.

After the installer for windows failed, I tried linux.   This is what I got: --- There has been an error. Failed to install dependencies: Chef Client The application will exit now. --- I installed the Oracle Java 8 JDK 202 and put it into the path, same I did on Windows.   Is there ANY installer that actually works?

I have a numeric entry widget that is not setting the default value I pass to it because it is saying that it is out of range from the min value set. But this is not true, my default value is 24 it is within the min and max (the max and min change based on what question you are on). I try the "hardcoded" way and set values that work but still get the same issue. Anyone have any idea what is going on. It works as expected sometimes and other time not.    Not Working  

After following the guide of single sign-on, I have successfully set up the SSO environment on Thingworx, however, the log off functionality does not work, when we clicked on the log off button, the user session is not removed in the system, what we can do to make SLO work on Thingworx.

Hello, I am trying to call a REST API, which is using https and certificate issued by Lets Encrypt, using Resources["ContentLoaderFunctions"].GetText   Unfortunately I am getting this error: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target. If I select the option ignoreSSLErrors: 1, then I get this error:   Certificate for hostname doesn't match any of the subject alternative names   I tried to import the server's certificate to Java certstore, but it didn't help. I am running ThingWorx 9 as Docker container. What do you think can be the problem?   Thank you for your help
