RE: use of relevance

Hi John,

 

Thanks for the reply. I checked out the switch module from Xforms
specification and the example they have given uses toggle action to switch
among the cases. The switch tag supports single value binding but how it can
be used to select a particular case? Can you give me some example?

 

Once again thanks for clarifying my doubts.

Meghana.

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.
