[TYPO3-mvc] ViewHelpers Setting/Updating variables restriction

[Sebastian Kurfürst]

Hey Robert,
> Each array entry has a key "name" and can have a key "children" with children for this entry.
> I thought of defining a section "renderTree" and call it recursively:
That's perfectly possible, try the following:

> <f:section name="renderTree">
>   <ul>
>   <f:for each="tree" as="entry">
>     <li>{entry.name}
>     <f:if "{entry.children}">
>       <f:then>
Throw out the following three lines:
>         <f:alias map="{tree: entry.children}">
>           <f:render section="renderTree" />
>         </f:alias>
And replace them by:
<f:render section="renderTree" arguments="{tree: entry.children}" />
That works with Fluid included in the newest stable TYPO3 release.
>       </f:then>
>     </f:if>
>     </li>
>   </f:for>
>   </ul>
> </f:section>


> Is there any way to write comments, that do not appear in the rendered source?
> I like to comment my templates, but I do not like it when all visitors of my page can see them.
> That's why I wrote a CommentViewHelper, which does not render it's children. But it is a lot of code to write for simple comments:
> <v:comment>This comment will not appear in the HTML-Source</v:comment>
Yep, that's the way to go. I agree that this is more to write than in
smarty, but on the other hand it clearly states that it is a comment --
nothing more, nothing less.

We should include this ViewHelper in the standard distribution...

Greets,
