[T5] Get Zone to Initially Render a Block

Problem:

I would like to have a textfield with a button/link beside it that when
clicked adds an additional textfield with another button beside it. I would
like this to be done with Ajax, but I am not sure how to have the first
textfield and button render initially.

I basically have:

<t:zone ...>
  <t:block ...>
    <t:loop ...>
      <t:textfield .../> <t:actionlink ...>...</t:actionlink>
    </t:loop>
  </t:block>
</t:zone>


However, with this approach the block will not be rendered initially (you
need to fire off the event and have the block returned first) and thus there
will be no actionlink to click. I'm not sure the way to proceed, but I don't
think the answer is to just add in a textfield with actionlink outside of
the block and have an extra event handler method for that actionlink.


Any ideas?

[T5]:addScriptLink with parameter

Posted by "Zheng, Xiahong" <Xi...@FMR.COM>.
Using addScriptLink() can only project <script type="text/javascript"
src="dojo/dojo.js"/>

I am wondering if it's possible to produce a script link like the
following,

    <script type="text/javascript" src="dojo/dojo.js" 
      djConfig="parseOnLoad: true"></script>

I am trying to write some T5 component using dojo which uses "djConfig"
paramenter.

Sorry, the java code should be:

    @Inject
    @Property
    private Block _formBlock;

    Object onActionFromAddBlock()
    {
        // code to add another item to list of items
        return _formBlock;
    }

I figured it out. Here is an example of my solution:

    <t:zone t:id="outputZone">
        <t:delegate to="formBlock"/>

        <t:block t:id="formBlock">
          <t:form>
            <t:errors/>

            <t:loop source="items" value="currentItem">
                <t:textfield value="currentItem.name"/> <t:actionlink
zone="outputZone" t:id="addBlock">+</t:actionlink><br/>
            </t:loop>
          </t:form>
        </t:block>
    </t:zone>

---
Object onActionFromAddBlock()
{
  // code to add another item to list of items
}
