how to preselect a combo box item

["Igor Kostic" <Igor.Kostic (at) oenb.at>]

I have a combobox with item/exportValue pairs.
I am trying to preselect an item using:

 

AcroFields flds = stamp.getAcroFields();
flds.setField(comboBoxName, itemExportValue);
stamp.close();

 

after opening this document in AR the item seems to be selected, but actualy is not - if the combobox gets focus, the selection is gone.
Am I doing something wrong?

 

Thanks,

Igor
