Hi,
We have a form that has multiple pages controled by tabs like in
the vcard Chiba sample.
I would like to be able to specify in the instance data what tab
should be open when the form is launched.
Any ideas on how this might be accomplished?
vcard is not a good starting point to assomplish this cause it uses the
<switch> element for creating 'pages'.
The <case> elements of a <switch> have to be statically authored and the
toggle action is the only way to change the selected card but toggle
only takes the idref of the target-case as argument - so in consequence
there's no way to set the selected <case> dynamically (dependent on
values in the instance).
To nevertheless reach your target you've to use groups that you bind to
relevant constraints thus being able to switch a group visible or not by
setting a value in the instance.
Have a look at the wizard-with-relevant.xhtml sample to get a feeling
how to implement dynamic 'pages'. This technique is a bit more complex
to implement but offers much more flexibility.
hope this helps,
Joern
Thanks,
Richard Steadman
