When creating a new topic using a formtemplate and initializing values using query params the value that is passed over is inserted twice into the form by CGI.pm, first by checking/selecting the option an second by setting the new hidden dummy field introduced in Item2410. The result of this is that while saving the topic the meta data value will be duplicated as Save.pm does not protect those fields being set by the same value twice.

Example: you get

The fix is to not to use CGI to create the hidden dummy field but use a plain <input type="hidden" name="SomeCheckBoxField" value="" /> string instead.



Setting MergeTo to "minor": The fix must have the same status as Item2410.
