Error the first time a form is shown

Classic Servoy
1

I am getting an error in developer the first time I show a particular form and I cannot find how to trap and locate it:

WARN org.sablo.websocket.WebsocketEndpoint - Warning: Access to component caseList property lastSelectionFirstElement denied (visible). Warning was caused by: Access to component xpCaseList_dtl property null denied (visible)

Can anyone give me some pointers please?

Thanks
Steve

If you can reproduce this with a small sample you should create a case and give a link to this discussion in it as well.
Servoy-extra table component is trying to change the value of a property in it’s model (used in it’s internal impl.) - both on client and server, but that change is denied on server because the form seems to be hidden or not yet visible.

I think I had something similar to this because I was trying to do something with a component in my ‘onLoad’ method, but the item wasn’t ‘visible’ so I moved the code to ‘onShow’ and it didn’t show the error.
See if that helps.
