I try to insert a checkbox in my xform, but I can´t use commas (,) in the name of an option. I get the error message: "Invalid value for options (,)"
This is reported as a bug and is fixed. However I don't know when it will be publically available. The fix allows commas in the name of an option. It will not be possible to use commas in the value since this will corrupt the posted form data.
