We're attempting to migrate a PowerBuilder app to PowerServer. The app runs great in PB 2019.
 
We’re trying to launch a user interactive process in a response window that must be available to the user AFTER the window is opened AND visible to the user.
 
In the response window’s “open" event (after code that initializes the window) we make the following call which is flagged by the PowerServer Analyzer as unsupported:
 
this.post event ue_response_run()
 
 
Using “trigger” rather than “post” (as in the following) doesn’t work because the code in “ue_respone_run” executes before the response window is visible to the user:
 
this.trigger event ue_response_run()

Hi Kai, thanks for the response. When I created a test case (attached) I couldn't recreate the issue (the analyzer does not flag the "post" event).

The application is rather large so I'll do some more testing in an attempt to better isolate the issue before creating a support ticket.

Hi Phyllip;

  As Zhao Kai mentioned, that form of the Post Event is supported by PowerServer. If not many applications based on the PFC would not work for example.

  I am not sure why your App is getting that syntax flagged. The other alternative (workaround) might be ...

Yield()

this.trigger event ue_response_run()

Regards ... Chris

Maybe there is something inside your ue_response_run() event which is not supported?
