Okay, found one more problem related to qrules and this post chain.
If you read the history of this question, you will note that my problem first manifested itself when I uploaded my form as an admin approved form and subsequently tried to use as a webform.
Well, same issue. Everything works great from any machine as an Infopath Native form, but when I click the button that sets the command field, no activity. Result, Success, and Error fields are not changed; no indication of saving, and the list is not updated.
Now, here is the interesting part, when I click "close" under the edit ribbon on the webform, all my changes to the page one form are saved to the server. I expected this to occur when I clicked the button to set the command field. However, I have similar buttons on page 2 and 3 that save to other lists and these buttons work as expected - click button, forms saves instantly without the need to "close" form.
Am I doing something wrong or is this the design behaviour of qrules in a webform?
