Hi Malek Taha,

if the datawindow can not be found during runtime:

Use a PBR or compile your application using PBDs/DLLs.

https://docs.appeon.com/pb2022r3/pbug/Distributing_resources.html

And yes... there is no warning or an exception if you code something like:

dw_test.dataobject = "you_will_never_see_me"

Hi The retrieve returns -1 after the switch

Hi Chris

     I am not sure how to debug. what do you mean by a "Ghost" DWO in the PBL?

Hi

   The whole datawindow dissapears.

I debug and after the switch the datawindow returns -1

Hi Chris

      The data windows worked fine I can open both and retrieve with no issue 

If i switch the datawindows on the window manually in the ide then run the app both datawindows retrieves with no issues.

This issue only appears when i do the switch of dw at runtime

There is no errors the app works fine after the switch, the datawindow just disappears  

Thanks

Malek

Hi, Malek - 

Does the entire DataWindow control vanish or only its contents?

If no rows are returned, you will not see any contents in the DataWindow control... so how many rows are returned by the dw_1.Retrieve after setting a new data object and assigning the transaction object? If none, you may have to issue an InsertRow(0) method to see the DW's data object.

Best regards, John

Sorry Chris
