My Scenario is:
I have Phone number validation for textbox like string-length(translate(., "()-X ", "")) > 15 and also two checkboxes which has rules for validating mutual exclusive(If one checkbox is selected the other one should disable). and when i published this form to sharepoint server, and enter some data in the phone textbox and soon after if i click the checkbox the rules(Mutual exclusive rules) applied to checkbox are not working. and from second time onwards its working only for the first time the check box rules are not firing. Its happening only for textbox which has string-length function.
If you need more details please let me know.
