Hi,

What entities you imported? Maybe you need to redo the bindings.

Also, check the Application.log to get a hint what it happening and upload here any relevant error/warning.

Thank you,

Hi,

Check the application key 'RE_Kepware', it is expired, don't know if you are using it in your mashup.

Change the expiration date and check again the mashup.

Hi,

In fact, Application Key expiration should not have any impact on the Mashup / List issues...

I'm going to ask the most frequent question in the IT world: Have you restarted the Tomcat? And hard-refreshed the Mashup?

BR,

JK.

Hi , 

Yes i tried refreshing , restarting the tomcat ... the thing is the list , combo box widget is not even visible ... i didn even bind the data but then also empty list is not visible.... if i bind data also its not visible ... pls check out the images i have attached ...

I am having the same exact issue after upgrading from 8.1 to 8.3.3. The temp solution was we used to correct the issue was to revert the Runtime directory to the 8.1 version and that worked but then broke other functionality such as collections.

Was a solution ever determined for this issue?
