problem with nested <xforms:group>

Hi,

I am experiencing some issues with nested <xforms:group> constructs being used in Orbeon 3.7.1. The behaviour that I have observed is that when the outer group toggles from disabled to enabled, it will by default show the inner <xforms:group>, even when the group is disabled.

In my example I have a label and an input control being controlled inside the nested group. When the outer group is disabled and re-enabled, the label inside the inner group will appear, even when the nested condition for the group is not true.

I have enclosed an demonstration of this happening in the link below.

Is this a known issue or is this a possible Orbeon bug? Do I need to rethink of how I am doing this and not use the nested <xforms:group> construct?

Many thanks,
Murray

Re: problem with nested <xforms:group>

Hi Murray,

The specification says that the group model

allows a form author to aggregate other form controls into a
single, aggregate user interface component.

http://www.w3.org/TR/xforms11/#ui-group-module

Also, the xforms-enabled (disabled, relevant) event is
not cancelable and bubbles.

So I would presume this means that enabling a group will
descend to children.

That said, perhaps it does not need to be a child. I have forms
that, when
one case is toggled, they send a message to case in another switch
(and area of the form) to enable:

<widget:tab id="a-tab">

<xforms:action ev:event="xforms-select">
<xforms:toggle case="events-case"/>
</xforms:action>
...

The tab widget is an embellished case.

HTH,
Hank

This doesn't look right. Can you share with us the example you were showing in that screencast, so we can run it in the XForms sandbox?

Alex,

Here is the example application from the demo I showed. I have one outer group with three nested groups in this example. An interesting point is that the input control seems to have the correct behaviour, it's only the labels that have the problem.

Thanks for your help.

Good catch. I managed to reproduce this in a simpler example and created a bug for this:

BTW, this is not an easy one to fix, so most likely not one we'll do very soon. I'd recommend you don't use nested groups around <xhtml:tr> or around <xhtml:td>.

This was an interested one to fix / implement, but it is now done. So you can use nested <xforms:group> in a table around a <xhtml:tr> or <xhtml:td>, just as you could before (and still can!) everywhere else.
