Design Studio 1.6 Error in triggering the event

Hi all,

I have developped a dashboard using Design Studio client. At first, it was working fine. But after, I began to get the following error when I open the client to edit my dashboard: Error in triggering the event "apps.state_change" While processing the current request, an exception occured which could not be handled by the application or the framework.

I developped my dashboard with Design Studio 1.5, after we upgrade to 1.6 version, it was still fine for some time. After, I began to get this error. We upgrade to SP2 and problem was not solved. (We are using Design Studio 1.6 SP2 Version16.2.1 now)

Dashboard is working in local mode and also BI platform. The only problem is that I cannot edit anything.

I have tried some ways to edit it: 1)I create a copy of my dashboard with "Save as" but it was also unsuccessful. It still get the same error when I opened the copied version. 2) I create a new dashboard. I copied the datasouces and start up code first. It worked until here. Then, I copied the layout (grids, charts, tabs etc.) and I get the same error.

I search SCN for this error, I have found the following link: It is said that upgrade has solved this issue. But my Design Studio version is higher than this posted solution.

Any help would be appreciated.

    Hi Simge,

    Thanks for sharing your research. Regarding the try and error approach reproducing the bug, did you find which component actually triggers the crash? Meaning move them one by one until you see the error again. Maybe that gives us another angle to look at the problem.

    The note and scn entry you shared, tell us that the problem originated from different datasource connection types and hierarchy node variables. Is that also the case with you too?

    There is also a newer version of the Design Studio client 16.2.2 if you would like to try that as well.

    Let me know how it goes.

    Kind regards
