I am developing an InfoPath 2010 form for deployment on a MOSS 2007 server. So basically I know that limits me to using the InfoPath 2007 format and features. :(
My client would like to have a drop-down with multi-select capabilities, there are 24 checkboxes. Since the multi-select ddl is not available in InfoPath 2007, I thought I could just make a bunch of check boxes in a group, and a text field for the 'Other' and apply validation rule to the group that at least 1 option must be checked, but no... that would be way too easy/logical, b/c you can't apply rules to groups.
I found this reference to help me do this, however, it seems a little outdated, and I cannot get it to work. It seems that everytime I run the form, all the rules I've applied to the checkboxes disappear, so there is no data validation. Does anyone have any suggestions/advice? Has anyone else found their rules disappearing?
Many thanks!
