nesting h:panelGrid within h:dataTable

I have a situation where I'm trying to display a simple ArrayList<MyRecord> within an <h:dataTable> outtput:

<h:dataTable value="#{form.queryBean.Records}" var="item">
<hutputText value="#{item.firstValue}"/>

<hutputText value="#{item.secondValue}"/>

(This works fine.)

However, I have a new situation now where I want to bind a nested <h:panelGrid> and define this within the MyRecord class.

So, instead of MyRecord being some simple bean with primitive objects and appropriate getters / setters, it now contains this embedded HtmlPanelGrid object:

public class MyRecord
private String firstValue;
private String secondValue;

private HtmlPanelGrid myPanel;

// appropriate getters and setters ...

public HtmlPanelGrid getMyPanel()
// set up and declare a list of children nodes inside here to be displayed back... This will
// be a collection of <hutputText> and <h:commandLink> children...



What I'd like to do is this: (modified from the original)

<h:dataTable value="#{form.queryBean.Records}" var="item">
<hutputText value="#{item.firstValue}"/>

<hutputText value="#{item.secondValue}"/>

<h:panelGrid binding="#{item.myPanel}"/>



...and call it done.

JSF 1.2 barfs on this declaration because it is trying to evaluate "item" here prematurely. (This dataTable is being built
after certain events happen on the form itself and is rendered appropriately once the data gets populated.) It makes sense to
do this inner binding in the application that I'm working with.

The question is - How do I get the appropriate syntax to work ? I've tried using the 'rendered' attribute, but JSF 1.2 seems to
ignore it when it's embedded like this. (rendered set within the parent <h:dataTable> tag.)

What am I doing wrong here ?

Appreciate any inputs.


I agree. Here's the link:
