Patrick,
Thanks for the reply. I guess using the term "save" was incorrect. I actually have the save option disabled. Yes,we use the Infopath Client to fill out forms. The form is submitted to a document library using the qRule ChangeSubmitUrl command. This allows us to submit the xml file to the project's folder.
When the project is "active", employees make changes to the form (updating status, etc) and the form is submitted to the DocLibrary/ProjectSpecificFolderName folder.
When the "Completed" check box on the form is checked (set to "true"), the form data is submitted to the DocLibrary/_completed/ProjectSpecificFolderName folder. The problem is a process issue. The folder and all related project files stored in it gets moved under the _Completed folder by a drag and drop from the SP explorer view. If the "Completed" check box does not get checked after the files are moved, the ChangeSubmitUrl command (Based on form rules) will attempt to submit it ot the original folder location, which no longer exists.
I have been trying to find a codeless way to move the folder and all the files contained in it to the _Completed folder or to simply rename the folder to indicate that the project is complete. If I could do that in Infopath, it would solve my problem as well.
