Cannot open data selection tool
I have an application which currently contains 3 different tabs. Each tab contains chart assigned to different datasources.
I added a new datasource to my application and attached it to a chart in my second tab.
When selecting the relevant KFs for the first time, everything is ok but when I try to select again I'm getting the above mentioned error "Cannot open data selection tool".
I think that this error effects also the application during run time: when moving between tabs 1 and 3 everything is OK but when selecting the second tab and selecting tab 1 or 3 after that, nothing is displayed in the charts.
I also attached a screenshot of the error description.
