I discovered following strange behaviour:
I have selected a value from a combobox (with a valuelist).
Then I excuted an empty method ( DO NOT ask me why i did this ) and the value list of the combobox pops up with all entries.
ShouldnM-4t the combobox just do nothing ?! It acts like hitting the select button again.
It is not so important - BUT.. it is a bug
