I installed it in my project and it works.
But I have another problem:
Before, as I had only 3 filters in the report 3 records would be displayed.(See 3-filters.jpg)
So far so good.
And now I have installed the fourth filter named "Vorgangstyp" from the enum and I get a NoDatamessage "Es gibt keine Daten zum anzeigen" (On english: "There is no data to display"). (See 4-filters.jpg)
But there must be datas to display - just less records!
Perhaps I have a syntaxerror in the table filter property. (See filter.jpg)
Or have I configured anything wrong?
