WebSessionContext “UnsupportedOperationException” exception

Targets Web
1

We have built multiple web app using Xojo 2021R2.1 that are broken when switching to Xojo 2021R3.

This code always fails in 2021R3 with “UnsupportedOperationException”.

—

dim context as WebSessionContext

context = New WebSessionContext(fMySession)

—

fMySession is a property of the WebPage that gets assigned during the Opening event to the current session.

It looks like a “fix” made a WebSessionContext in 2021R3 for bug report 60734 may have introduced a bigger bug. Hopefully, I’m wrong and there is a known work-around so I can use 2021R3.

You’ll need to run this code in a main thread event. Have a look at this conversation.
