Hi, I am using manufacturing apps through ThingWorx 8.2. I connected to the kepware but the manufacturing apps is not reading the tags and showing no status. Please help me on how to connect to the tags and develop OEE, availability and other parameters. Thanks, Shalini V.

Hello, I am new to ThingWorx and I am developing an Alexa Skill (Service Provider) which wants the data from ThingWorx (resource provider). I want to Authorize the users who enables this developed skill by asking them to sign up to the thingworx application for the first time and the communication between the Alexa and Thingworx from then on would happen with Access Token and not AppKey or Passwords. For this mechanism to work, ThingWorx should support OAuth2.0. So far I could not find any documentation (except the one describing SSO using PingFederate), which is totally a different scenario. Could anybody give some hints regarding this Alexa-ThingWorx-Access Token scenario. Thanks in advance 🙂

how to display the hierarchical data in form of tree in mashup as shown in the image.    

I'm having issues viewing custom widgets in a mashup (ThingWorx 8.2).  I followed all of the steps on Article CS246176 (https://www.ptc.com/en/support/article?n=CS246176&source=snippet) but I still get the "<widgetName>does not exist" error on run-time.  At first I tried a widget that I created with the d3 library.  Then, just to check my sanity I created a simple "hello world" like widget in Eclipse.  Both of them throw the same error.  Are there any newer widgets in the marketplace that, if installed, cause issues akin to what the aforementioned article addresses (i.e. d3 tree, network, and custom chart widgets)?  Or has anybody else found a solution to this issue?

I have a service retrieving a json file from several devices via the contentloaderfunction getjson. After the json is retrieved I parse the data and output an infotable and display the values in a mashup. If the service fails the widgets displaying the data show errors on my mashup. I would prefer to show no data vs an errored widget. Is there anyway to have the service return an empty infotable?

Hi,   We have a TWX 8.2.5 on a Windows Server with MSSQL DB in an offline Production Environment. We tried to update some parts of the running TWX Application (Mashups and some backend functionality in Things etc.) But we can not update entities in Composer or import new Extensions because of this generic error: [[1'018] Data store unknown error: [......"   What are possible causes of this error? - Space on devices is good >20GB on the two harddrives. - Memory is ok with room for more - Tomcat and MSSQL restarted serveral times - Tomcat configurations without Memory Settings   What can we try to fix this error? We didn't have access to the instance all the time. So I want to check all possibilities before connecting again. Attached a small screenshot from logview

Hi,   I have a mashup in which on button click I am showing a list as sub menu to that button. The submenu is having a service binding which is providing items list as well as mashup name to which the navigation should happen. I am showing that navigated mashups as popups.   This thing is working well on first sub menu selection. It shows the popup according to our selection. If the popup is closed and the button is clicked for showing list of sub menus then it shows the previous selected popup (mashup) automatically. It looks that there is some issue with the binding and 'selectedRowChanged' event.   The same implementation is working in Thingworx version 8.3.1 and not working in 8.3.3.   I am expecting some help to fix this issue. Please comment below if you need any more information.   Thanks, Chetan Purohit

I am trying to set properties of a remote thing from mashup dashboard. I can set properties using one of the following 1.Mashup only service -SetProperties 2.Snippets that can be called from custom service -UpdatePropertyValues -UpdateSubscribedPropertyValues -SetPropertyValues   All of the above have output type NOTHING.I want to retrieve the output(i.e http response if any) and display error message in mashup if service call failed due to some reason. Eg: Edge device not connected or some custom error message from remote thing's script handler   Is there any way to retrieve the response/output when trying to set properties to remote thing from service?   Note: Thingworx Composer displays error message when trying to set property from Thing's properties.Looking to implement  a similiar functionality from thingworx dashboard.

Hi, we are having an issue with how the time string is displaying in a grid widget (in fact all relevant widgets). We are using the  default format token 'dateTimeFormat_Default'  which has the value(s) 'yyyy-MM-dd HH:mm:ss' in the Default localization table 'yyyy-MM-dd HH:mm:ss.SSS' in the System table all other tables have no value. In the grid widget the text displayed is 'Thu Jan 17 2019 16:52:04 GMT+0000 (Greenwich Mean Time)' . Column Renderer & State Format settings are: Renderer = DATETIME Format = dateTimeFormat_Default Fixed Style If I bind the single rows time value to a Value display widget and set the renderer to DATETIME & dateTimeFormat_Default I don't see any value. If I set it to STRING I see 'Thu Jan 17 2019 16:52:04 GMT+0000 (Greenwich Mean Time)'. I have tried changing to other date format tokens but they have no effect at all and I see the same strings. We have just upgraded to 8.2 (from 7.3). Everything worked fine in 7.3.
