Using region attributes to populate train skip property

Question

Hi Steven,
It's been a while since I've looked at trains in 11g and now that I picked it up again I'm working on using the "skip" property of the train stop.
Back in this thread Adding EL expression to train skip property you suggested modifying the groupAdfcConfig template like :
#if ($JHS.current.group.wizardBaseGroup)
<train-stop>
#if ($page.itemRegion)
<display-name>#REGION_TITLE($page.itemRegion)</display-name>
#elseif ($page.regionContainer)
<display-name>#REGION_TITLE($page.regionContainer)</display-name>
#else
<display-name>#GROUP_TITLE($page.group)</display-name>
#end
*<skip>${page.group.property1}</skip>*
</train-stop>
#end
The problem with this is that the skip values need to be provided at the region level (ie for each stop) rather than just once for the top level group. I've played around with the groupAdfcConfig template and now have it looking like
#if ($JHS.current.group.wizardBaseGroup)
<train-stop id="#NEW_ID("__")">
#if ($page.itemRegion)
<display-name id="#NEW_ID("__")">#REGION_TITLE($page.itemRegion)</display-name>
*<skip>${page.itemRegion.rendered}</skip>*
#elseif ($page.regionContainer)
<display-name id="#NEW_ID("__")">#REGION_TITLE($page.regionContainer)</display-name>
*<skip>${page.regionContainer.rendered}</skip>*
#else
<display-name id="#NEW_ID("__")">#GROUP_TITLE($page.group)</display-name>
#end
</train-stop>
#end
.. using the rendered property of the train region to populate the skip property. The problem I am currently facing is when I'm using a group region because there is no ${page.groupRegion} method. You simply default to ${page.group} for the group region to get the display name but the trouble with that is there is no method in the PGGroup class to retrieve the rendered attribute. For now, I've had to wrap the group region inside a region container just to be able to get the rendered attribute property back.
Is there a way I can access the rendered property of the group Region ?
Cheers,
Brent

Brent,
We would need to change the generator code for that. Can't you put the group region inside a region container an set the rendered property on the region container instead?
