Hi Ingo,
the data sources are loaded automatically. I tried to load the data source in the script, no difference. Also reload the datasource between Setting of the filters and the readout in the Dropdown boxes leads to the same error.
Since the Dropdown Boxes are empty when the script is combined into one, it looks to me as if the setFilter command is not yet executed properly when the Dropdown Boxes are filled. In this case, I would need a checkpoint that waits until the filtering is finished properly. However, such a functionality (wait until...) is to my knowledge not yet implemented?!
For simplicity, I did not mention earlier, that before the Setting of the filter, i first clear all filters.
Regards
Julian
