Hello,

is anyone here who could help me?

I've spent plenty of hours by searching the correct and suitable way for creating a binding exception in XForms, but I did not succeed...

My situation is: I've got an XHTML page with XForms and XML (input) file, which describes this page. Whenewer I change the input data in the XML file (for example if there are tags <person> and ....</person> if I change it to <peson1> and ...</person1>) after saving the changes and refreshing the page, the XForms are changed (for example some text fields are missing or they've got white background instead red one, which there was before et cetera). {I hope it is clear till now.....}

My task is: to create a xforms-binding-expression event, which will display an error message (for example: FILE HAVE BEEN CHANGED, CAN NOT DISPLAY THE PAGE PROPERLY) to the user.

i've found some stuff, how to create such message, but i need to know the exact order of commands to make it work, where to insert them, the structure etc, so I can comprehend your advices...

The XHTML file contains of several blocks - bind, model, submission, instance etc - and I do not actually know, where to insert such lines (with message)...I think I should make some bindings with the page loading, but I've got no idea how to get it done, however there are very few sites with such stuff on the internet. I hope this task is no big deal for you gyus, THANK YOU A LOT IN ADVANCE
