I have infopath form called abc.xsn which I published into sharepoint library. The abc.xsn having a combo box whose data is populated by sharepoint list say, slist. I designed another form called master.xsn which is used to update the slist(sharepoint list) using the managed code. I placed a button in the abc.xsn and choose the action (open a new form to fill out) and given the sharepoint location of the master.xsn file. I checked it on my local machine it worked fine. But after I published the abc.xsn again to the document library and I open the published form and clicking the button to open the master.xsn it throws me error saying "Some rules where not applied" with Details msg as "InfoPath cannot create a new, blank form. Access is denied." My trust setting is DOMAIN and also I have both document placed in same sharepoint 2007 site. My Infopath form's are NOT browser compatible. Any help is appreciated. Thanks
