[T5] Rendering a block a component received as parameter
Hi there,
I am developing a tree component which can take several classes as
nodes. Each class should have it's own body, stored in parameters - and
then rendered, of course.
Now, lets say I have I have this code in my Test.tml:
--------------------------------------------------------------------------
<t:ExTree t:id="taskTree" source="treeNodes" currentNode="currentTreeNode">
<t:parameter name="taskClassContent">
<t:pagelink t:page="Task"
context="${ognl:currentTreeNode.id}">${ognl:currentTreeNode.title}</t:pagelink>
</t:parameter>
<t:parameter name="projectClassContent">
<t:pagelink t:page="Project"
context="${ognl:currentTreeNode.id}">${ognl:currentTreeNode.projectName}</t:pagelink>
</t:parameter>
</t:ExTree>
--------------------------------------------------------------------------
As you can see, taskClassContent and projectClassContent are Block elements.
Now how can I render this Block element in my ExTree component? By the
way, ExTree hasn't a template, just a class.
Hope that someone can help me,
Tobias

But you can't use a delegate component without a template, right?

Another option is to use the Delegate component and pass it the Block instance.

Hi Josh,
thanks, this works great!
I think I understand the rendering process now a little bit better, so a
Delegate would have been fine too - thank you, Howard. I just didn't
understand how to render that Delegate before, since it is a component
too. (I hope I now understand it correctly that I just would've put it
in the Template and set the Block which should be rendered in
beforeRenderTemplate.)

I don't recall if you can use MarkupWriter to write blocks yet, but one
method I've used is to return the block from the beginRender method, it's
rendered after whatever you write within the method. I believe for both
blocks you would have to use both beginRender and beforeRenderTemplate, or I
suppose you could loop from the beginRender method.
If you want to wrap your blocks in an element you would start it in
beginRender and finish it in afterRender...
In the case you've laid out though, it might be easier to just create a
template.
