I managed to concatenate a list of entries into a "Multi-Line Entry" field (to get around the max. length limitation of 255 chars of the "Single Line Entry" field).
Though I can select it in the data grid configuration, the UI does not provide the "contains" operator I would need here. And I also cannot provide the "source table", as I'm on an App Page, where tables are not available (at least, there is no "Advanced" section shown in the design elements...).
Now, when I try to set the filters via javascript in the "onShow" or "onDataChange" event of the data grid as follows (though not shown, the line is complete/correct)
I always get this cryptic message (for search engines in writing: The submission record does not exist) when testing/opening my application.
If I remove this single line in the filter, the message does not appear, but I would need the grid to be filtered by/for the current user...
A Google Search returns exactly one hit, pointing to the forum here,
https://support.hcl-software.com/community?id=community_question&sys_id=a0a2df6c1bf69c50a2f48661cd4bcbe6
but tackles some access bug which should have been addressed quite some time ago.
Despite, I'm logged in and am trying to get my own documents, so this doesn't quite fit my case...
Any ideas how I can get this to work?
