InfoPath Dev

Hi all, I am trying to modify the workflow associated form in infopath 2010. But while I opened this task form in infopath 2010 I cant see the Developer Option from the toolbar(so code behind is not possible) and i can not see the repeating table control in the toolbox also, where as if I designed a new form template i can see all this option. By the way I am trying to populate the workflow initiator information(like repeating table info from initiator infopath repeating table and other control information) in approver task form. Please somebody help me to achieve this.....pls

To answer the first part of your question, the repeating table is likely not compatible with workflow forms which is why you cannot see it in the controls gallery.  The gallery only displays controls that are supported in that mode which is why you can see most controls in a new blank form.  I don't think code behind is possible in a workflow form either.
