Created attachment 142924 [details] Example odt with multiple option buttons Insert some Option Button into the *.odt or *.docx file and set a group name of the option buttons. If we set a group name we can select only one option button, but if we export the document to PDF (to Create PDF form) we can check all of them. Steps to reproduce: 1. Create a new *.odt or *.docx file with LibreOffice Writer. 2. Insert option buttons into the document. 3. Set a Group name of the option buttons in the “Option Button-Properties”. 4. Select an option button you created. 5. Export the document as PDF with the “Create PDF form” option. (Submit format: FDF) 6. Open the exported PDF with Adobe Reader. Actual results: After we opened the file with Adobe Reader, none of the option buttons were selected. All option button can be selected at the same time, because the previously selected option button will not be unchecked, after we selected another option button. Expected results: After the export the correct option button should be checked, and we should be able to check only one option button in the same group.

A workaround is to give each option button NAME to be identical. The code for this is in toolbox/source/helper/formpdfexport.cxx determineRadioGroupId(). But this is really scary code because it looks like it is doing it all wrong, and did anyone even test this when they coded it? And if this is working for some specific situation, then changes would break that. Git history doesn't help much - basically unmodified since initial code dump at commit cda7d3dc154a74cd914bf21bc7eeb8c43bb6e154 Author: Vladimir Glazounov <vg@openoffice.org> Date: Tue Aug 19 21:10:58 2008 +0000 INTEGRATION: CWS aw033 (1.1.2); FILE ADDED 2008/08/19 16:46:47 cl 1.1.2.2: fixed license files 2007/08/07 15:40:47 aw 1.1.2.1: #i39532# migrated describePDFControl to toolkit
I'm going to guess at what happened here. Likely, originally OOo implemented radio button groupping by assigning the same name to each button. Then at some point they added the "GroupName" property to the radio button to store that information, but the PDF export code was never modified. That is the only explanation that I can think of that would make sense of this situation.

Created attachment 146267 [details] optionButtons.odt: make sure two option groups still work (and bug 108687 test) My proposed patch didn't accept the previous behaviour. That might be OK if necessary, but it should be possible to support both methods, so that people who have spent a lot time figuring out how to work around LibreOffice's poor PDF export of radio buttons don't have to redesign just because GroupNamme is now supported.
