Invalid Canary for view file

After we installed Infrastructure Updates we started to experience some problems with InfoPath Forms - getting "There has been an error while loading the form. A required resource could not be downloaded. To try to resume the download, refresh the page.", when using some of the alternative URLs.

SharePoint logs was showing me "WARNING: Invalid Canary for view file"

Based on the info from the Microsoft, there is an known problem with the Alternate Access Mapping in Infrastructure Updates. The next cumulative update is supposed to fix this issue. Will update this post as soon as I get it installed and verified.

Update: After installing SP2 issue was fixed.

InfoPath property promotion (field association) problem

Just experienced the following problem today - spend a couple hours on figuring it out: I have a full-trusted infoPath form that is allready published and working. There were a few form properties/fields associated with the fields/columns in the SharePoint. I have tried adding a few additional - but it didn't work. The fields were there, the values were inside of the InfoPath form, but they were not carried over to SharePoint. It looks like you need to reactivate (deactivate first and activate again) this form for the site collection from the Central Admin in order for those associations to be refreshed.

InfoPath 2007 Bug - Form Does not Submit

Encountered weird InfoPath bug. Had an Approval Workflow with the InfoPath 2007 Web Form (MOSS). User had problems submitting the Form, click on the submit button was doing nothing. Reopening the Form was enough to submit. I watched how user worked with the Form, and noticed that the user was double clicking on the email link, which was causing the form to load twice (in two IE tabs). Changing this habit to clicking only once - solved the problem completely.

I have no idea why double loading the form was preventing it from submitting, but that's what it was.
