R – Workflowing an InfoPath form

It's been a while since I did anything InfoPath, so apologies for this being a little vague:

Part of the InfoPath template, which is pretty much just a ZIP archive with a different extension, is a file called "upgrade.xsl". This file contains one or more XSL transformations that "upgrade" documents targeting earlier schema versions.

The question is: Why does the correct transformation get applied in one scenario (SharePoint/Form Library) and not in the other (web service)? Is the second process possibly losing the tag that InfoPath uses to know the version of the schema that the source document is targeting? I believe the tag I'm referring to is the "?mso-infoPathSolution" tag ("solutionVersion" attribute).

If this tag is indeed being stripped from the document (and you can't easily prevent it), you may need to apply the appropriate XSL transformation "manually". Of course, if there are multiple versions you are dealing with, it could be difficult to determine what transformation needs to be applied in any case.

I have not found a method to kick off a workflow specifically from an Infopath form. I did however find a workaround; here's how I set it up:

1. Added a column to my list/library that will be set to true when the cancel button is selected.
2. In my infopath form, add my "cancel" button.
3. Open the control properties for the button, and select the "Rules" action. Close out of the properties dialog.
4. I added a fomatting rule for the cancel button so it will only display if the first workflow has started. I also disabled all other editing controls as I only wanted the cancel option to be available.
5. On the Control Tools contextual tab, in the Button group, click Manage Rules.
6. Add a new Action rule, it should run two actions: first set the value of the column we created in the first step to true; second submit data using the main data connection.
7. The workflow you want to run when it is cancelled should be set to run on change. As a first step, evaluate the column created above, and if true, continue the worflow. Make sure you set the value back to false so the workflow doesn't run unintentionally.

Hope that helps.
