Question about web socket feature in TW

[tarik]

 

I'm using the web socket feature in TW 7.3 (from Automatically update values when able checkbox), the feature worked only for one time and it didn't work after that at all,

I have the three error messages in the application  log as the following:

Message1:[context: com.thingworx.webservices.context.HttpExecutionContext@24f88415][message: Unable to Invoke Service GetClientApplicationKey on EntityServices : Import Failed: Unable to create applicationKey: [1,018] Data store unknown error: [Error occurred while accessing the model provider.]]

Message2:Unable to process import: Unable to create applicationKey: [1,018] Data store unknown error: [Error occurred while accessing the model provider.]

Message3:[message: [1,018] Data store unknown error: [Error occurred while accessing the model provider.]]

Could you help me please identify the problem I'm facing.

Thanks in advance,

 You did binded any property of GetProperties result to a visual widget?

[tarik]

yes, I did Carles, the button increase the counter and the getProperties is bounded to the label, after I click the button the label doesn't get updated

[tarik]

I noticed that I have 3 error message, I'll update the question

[CarlesColl]

And DataChange event for Counter property it's thrown? I mean, which kind of Data Change Type it's defined for counter property?

[tarik]

The Data Change Type is: Value
please also note the errors I have updated in the question

It maybe a permissioning problem as it says it was unable to create the Application Key, which it's necessary in order to "Push Properties" to work as described on the documentation: http://support.ptc.com/help/thingworx_hc/thingworx_7_hc/#page/ThingWorx_Help_Center%2FThingWorxHelpCenterDITAFiles%2FMashupBuilder%2FMashups%2FMashupAutoUpdate.html%23

Or, just thinking loud, you may have a different authentication system than the TW Standard one (Directory Services / Authenticators) and that's why the Application Key system doesn't works....

You can create Application Keys freely with the Composer?

Hi Carles,

Sorry for being late, actually I can create new app key and this is the method I'm using for authentication.
