Hi,
I had a very similar problem today too. Sometimes the body was
rendered, other times just nothing was rendered.
My workaround was to define a block containing the body part, pass
this block to the "report" and have it rendered through <t:Deleget
to="passedBlock" />
your report.tml would look like
<t:loop source="items" value="row">
<tr>
<td> test </td>
<t:delegate to="passedBlock" />
</tr>
</t:loop>
the page would be
<t:report t:id="users" model="reportModel" row="userObject"
passedBlock="innerBlock"/>
<t:block t:id="innerBlock">
<td> blah blah </td>
<td> ${userObject.username} </td>
</t:block>
you'd have to define passedBlock in report.java and innerblock in
page.java
like
@Inject
@Property
private Block passedBlock;
Hope this helps.
Problems like this make me nervous. I hope someone could explain why
it is not working as expected.
Regards
Moritz

hi,
this is one of these 'mysterious' problems. i have a component
(report)
which takes a datasource and draws a table filled with data. something
like a grid component provided by tapestry.
this is essencial part of .tml:
<t:loop source="items" value="row">
<tr>
<td> test </td>
<t:body />
</tr>
</t:loop>
and this is part of .tml of the page which uses my component:
<t:report t:id="users" model="reportModel" row="userObject">
<td> blah blah </td>
<td> ${userObject.username} </td>
</t:report>
it works perfectly ok. well, almost. sometimes it happens that
component's body is not drawn! precisely it is not returned inside
response to XHR which updates the component.
i ensured that 'items' collection is not empty (<td> test </td> is
drawn
correctly as many times as items.size()) and checked assigned
userObject
(which is correct non-null object).
the problem is that whole the component is drawn as it should but
<t:body/> tag is _sometimes_ ignored. i cannot even reproduce this
problem easily.
there is no @BeforeRenderBody function in my component.
could you please give me a hint where should I start investigating
this
problem?
thanks a lot,
m.
