I am having some problems with a selectItem:
EntryPoint:
MyWindow:
table.ds.xml:
In order to reproduce the problem, the table t_textfragmente should initially have 4 records with titles "1", "2", "3", and "4". (1.png).
Then, delete them in order "1", "2", "3", and then "4" using the button "Delete Record".
Finally, write "1" in the textfield and push "Add". The record is added and the selectItem is updated (2.png). But why do I see many empty rows? (2.png)
Similar scenarios happen when adding 4 records and immediatly removing the first of them: then I see one empty row in the selectItem.
When I open the window again, I don't see any empty rows, which is the correct behavior. But something is going wrong, see 2.png.
Can you reproduce the problem?
