RE: use of relevance

Hi Meghana,
 
One option is to use a switch to control what is visible.
 
Another is to create a submission instance distinct from the processing instance.  The processing instance would have relevant MIPs, but the submission instance wouldn't.  Either using calculate binds or using setvalue actions in an xforms-submit handler, copy the data to the submission instance before submission takes place.  This will get easier in XForms 1.1 with a copy subtree action (which is as yet unnamed).
 
Cheers,
John Boyer

I wonder how xforms handles a case when a control becomes irrelevant based on value of the instance data but the submission still needs to submit that value. Or in that case we are not supposed to use relevance and use something else? What is that other option?

Hi Meghana,

 

The first one.  Relevance applies to instance nodes.  The relevant MIP is then interpreted by both bound form controls and submission.

Hello,

 

When a <Bind> element has relevance attribute, is it supposed to make the bound element in the XForms model relevant or the bound control relevant? In the former case, the control will see that the model is not relevant right now and hide itself; also the submission will not include that value. In the later case, the control is hidden but model still holds that value as valid data. Which approach is correct?

 

Thanks,

Meghana.
