Hi All,

I have a question about submit processing. At 
you can read:

2. All selected instance data nodes are checked for validity according 
to the definition in 4.3.5 The xforms-revalidate Event (no notification 
events are marked for dispatching due to this operation). Any selected 
instance data node that is required but empty or found to be invalid 
stops submission processing after dispatching event xforms-submit-error.

My question is: How is the UI expected to behave in case some nodes are 
found to be invalid ?

Since no notification events are marked for dispatching one could draw 
the conclusion that the UI isn't updated as well. But this would mean 
that the user won't see which fields are invalid and caused the 
submission to fail. There could be an event handler for 
xforms-submit-error executing a xf:refresh in order to update all 
control's states, but I don't think this would be good option. That way 
the form authors would be forced to attach such an event handler to any 
xf:submission just to be able to visualize what went wrong. So how 
can/should this be accomplished ?
