Cascading parameter no longer works when migrating to BIRT 4.20

[MSDelorme]

Did anybody else notice issues with the cascading parameter interface. Before we used 4.13 and there it worked fine. When the parameter window opens and I change the first parameter of the cascading parameters the popup ' processing , please wait' pops up and nothing happens and it keeps on reports in progress, The cancel button also doesn't do anything. Before I announce this as a regration is there something I can look what the cause could be ?

In the cascading parameter I just have 2 parameters with each its own data set. ( so multiple data set is selected).

Can you provide please a test report with your problem based on th demo db classic cars.
So we woul have the same example for error tracking and debugging.

I will provide a sample over 2 weeks. Also to see if I can reproduce this error with another DB

It was easy to reproduce. After selecting the first parameter it now opens the processing , please wait pop up and nothing happens. I do realize there can also be external factors in play here. So lets see others can reproduce this issue also.
