We can set a message when there is an orbeon error with event.
<xforms:message ev:event="xforms-submit-error" level="modal"> Error Message </xforms:message>

When a form is submitted, if user clicks any button on the screen by mistake before submission completes, we are seeing a ‘Already Submitted on user interface as orbeon..” error. Can we avoid it by displaying our own simple message?
