InfoPath Dev

Hi ,

Buttons on infopath forms gets disabled randomly when published on sharepoint

when page is refteshed it gives fallowing error : 

The data posted from the browser is invalid. This may arise if a button (with an action other than rules) has been set never to send form data to the server.

Look at the button properties and check the postback settings under the Browser Forms tab. Are the controls in question set to 'Never'? You may want to try changing that to a different option.
