What I have is a datatable in a template with the detailStamp facet:
<table jsfc="t:dataTable"
...
value="#{myBean.myModel}"
var="myItem"
varDetailToggler="detailToggler">
... some columns ...
<span jsfc="f:facet" name="detailStamp">
<ui:include src="itemdetails.xhtml">
<ui:param name="item" value="#{myItem}"/>
</ui:include>
</span>
</table>
The itemdetails.xhtml displays details to the item, e.g. it iterates
over some detail options like the following:
<ui:repeat var="option" value="#{item.myOptions}">
#{option.description}
</ui:repeat>
So the the myBean.myModel.myOptions method is requested when the detailStamp
is displayed for one item, this method is invoked when rendering happens.
When myBean.myModel.myOptions is invoked the first time, I do some lazy
initialization, this might cause errors...
I do not see how I could do the processing in the invoke application, because
the detailStamp is shown via HtmlDataTable.toggleDetail, which is invoked
during invoke-application, but there's no possibility of specifying a listener
that is invoked when toggleDetail is invoked...
I hope this clarifies the problem a little bit, if s.th. is missing please
let me know!
Thanx a lot,
cheers,
Martin
