Hi PoDoFo devs! I'm using Ubuntu Bionic 18.04 and a shipped version of PoDoFo which is 0.9.5-9. I use FormTest.cpp to update the existing PDF document with just a single text field (please find it attached, it's name.pdf). I modified FormTest so it updates all the text fields to "xxx". FormTest is able to update the document and save it as name-edit.pdf. However, the text field in name-edit.pdf is still empty. If I click on it, a lineedit with "xxx" appears. But if it loses the focus, it reverts to an empty text again. Could you please help me with the issue?
