No variables in t:column header facets! Bug?
The header will be blank if I do the following
[code]
<t:dataTable id="projectsDataTable" var="project"
value="#{projectBacker.projects}">
<t:column id="projectNameColumn">
<f:facet name="header"><h:outputText value="#{project.status}"/></f:facet>
<h:outputText value="#{project.status}"/>
</t:column>
...
[/code]
Is there an obvious reason? All of the projects definitely have a status.
Thanks in advance
- Octoberdan

How can I do as I described? Does my other recent post have the same
answer?

The header is printed before there is an active row. In your text, you
are trying to print the status property of the GLOBAL variable
'project' since there is no 'project' variable in the data table yet.
<thead>
...
</thead>
<tbody>
row iteration starts
</tbody>
There is no "project" when <t:column><f:facet name="header"/> is rendered.

You can also use:
<t:dataTable value="#{bean.data}"/>
where data in this case is an instance of "javax.faces.model.DataModel"

Just remember that UIData subclasses all use
getRowData()/getRowIndex() and this is still true for UIColumns.
So to get the current column, you'd still use UIColumns.getRowData().

UIColumns is basically a UIData "turned sideways"
So you have a data model for your rows, and then you have a second
data model for each of your columns.
crossDataTable.jsp in myfaces-example-simple gives an example of using it.
"Live" online demo is here -- lets you add columns each submit.

I think it would be something like:
UIData data = new UIData();
UIColumn col = new UIColumn();
data.getChildren().add(col);
etc.
You are basically building the component tree by hand.
I think tomahawk has a "columns" item too ("UIColumns") that may be less work.
Has anyone else done this to provide more knowledge than me?
Thanks,
Andrew

Looking over the classes methods there doesn't seem to be any able to add
columns...

I tried looking for a relavent example but can't seem to find one... do you
know of any by chance?

I actually haven't done it. Here is a start:
<t:dataTable binding="#{bean.data}" />
where "data" is a property that returns an instance of
"javax.faces.component.UIData".
Then you would just build this UIData component programatically in
your backing bean.
Searching for posts and/or tutorials should help more.
Good luck,

If you are building a dataTable as a grid with dynamic columns, then
using the binding to a dynamic datamodel is probably what you are
looking for.

>>From which project (row) should the header value taken?
Well, I'm really trying to do this with t:colomns, but I was having some
problems with that so I used this as an example.

Hi,
you can't access the dataTables 'var' object in headers or footers!
