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.

[MSDelorme]

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

[MSDelorme]

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.

I have tested your report. The cascading confused my a little bit because your 2. data set doesn't used any filtering of the dependend paramter.

I have added a filter condition to your data set and afterwards it was working.

Here is your test report with my small change:

I my original report I select a DB with parameter 1 and than parameter 2 is a list of documents from that DB. This same construction doesn't work in 4.20 so far. If you test the report I uploaded and load in 4.13 you will see it does work directly. So I still think there is a some regression. I will also try to see if I can tweak my report on 4.20 to make it work

[MSDelorme]

In your updated example if I change parameter1 I still get the endless waiting pop up. (in 4.13 it al works fine).

Maybe try 4.21 which is probably what @speckyspooky tested and is also the version where things can still be fixed (and where there might be newer problems worth knowing about before it's too late).

[MSDelorme]

@speckyspooky I will try that.

[MSDelorme]

I can confirm it works again in 4.21. So indeed it was a regression

Oh, that's great and and annoying.

I expect we will produce a release around September 10 because we try to keep close to the SimRel schedule for releases:

• https://github.com/eclipse-simrel/.github/blob/main/wiki/SimRel/2025-09.md
• 4.21 Releng #2184
