Addition of xforms:group

Hi

In my UI, I am showing some widgets dynamically using xforms:group.
There are 3 such groups and they are mutually exclusive. What I need now is, I should be able to show collection  of all 3 xforms:group.

My question is:
Is it possible to define :
group-all = group1 + group2 + group3
(I mean can I  use xpath expression in my model?)

with regards

quick & dirty - you can use it using calculate - this means that you add an initially empty parent node for the aggregated groups to your model and add a binding to it:

<xforms:bind nodeset="instance('your-instance')/parent-of-aggregation" calculate="/path-to/group" />

or, if the groups have different paths:

<xforms:bind nodeset="instance('your-instance')/parent-of-aggregation" calculate="/path-to/group1 | /path-to/group2 | /path-to/group3" />

Hi florian

In the expression :

<xforms:bind nodeset="instance('your-instance')/parent-of-aggregation" calculate="/path-to/group1 | /path-to/group2 | /path-to/group3" />

/path-to/group1(2,3) is path in the model or path in the view (body)

The model. The aggregation can be completely independent from the view,
it's just a "copy" of some parts of a instance that's part of the model.
