Description
This used to work, now it doesn't, so this probably broke recently. I have a component that's a wrapper around a Grid to implement a list--> detail ajax update. So far so good, it works if it starts visible in a page.
Then elsewhere, I re-use that component, but its hidden behind a button that shows the grid via a progressive display and Ajax.
The grid appears, but the click on the grid gets a javascript error because its calling $T(null) so no details appear. This used to work. I asked on the list, and Howard said:
"This sounds like a new bug, some kind of order-of-operations problem.
Please add an issue."
I also note that $T is supposed to be deprecated anyways.
Details:
I have a component I'll call "EntityGrid". Basically, its wrapper around the Grid. When you click on an item in the GRid, a Zone gets refreshed displaying details about that item.
TML:
<t:container xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd" xmlns
="tapestry:parameter">
<t:zone t:id="popupZoneActivation">
</t:zone>
<table t:type="grid" t:source="activationSource" t:row="activation" t:id="grid" t:rowClass="prop:evenOdd.next" model="model" t:inPlace="true">
<t:parameter name="uuidCell">
<a t:type="eventlink" class="buttonPopup" t:zone="popupZoneActivation" t:context="activation.uuid" t:event="popup" href="#">${activation.uuid}</a>
</t:parameter>
<p:empty>
<p>There are no activation records to display. </p>
</p:empty>
</table>
<t:block id="activationDetails">
<script> document.location.hash=""; document.location.hash="popupZoneActivation";</script>
<div>
<div id="formsectionPopup">
<span t:type="pace/view/ActivationViewShort" t:id="activationView" t:activation="detailActivation"></span>
<span id="popupbuttons">
<t:pagelink class="button" t:id="ViewActivationLink" page="pace/view/${detailActivation.class.simpleName}" context="detailActivation.uuid">View Detail</t:pagelink>
<t:pace.schemaeditlink class="button" t:id="EditActivationLink" listSource="activationSource" label="literal:Edit" ourState="ourState" steps="literal:1" source="detailActivation"/>
</span>
</div>
</div>
</t:block>
</t:container>
The above works at the top level in a page. Elsewhere, I have it behind a button (because fetching the grid might be slow):
Hidden behind button TML:
<hr />
<h2>activations</h2>
<t:zone t:id="popupZoneactivations">
<a class="button" t:type="eventlink" t:zone="popupZoneactivations" t:context="literal:activations" t:event="showToMany">Show activations</a>
</t:zone>
<t:block id="activationsGridBlock">
<t:progressivedisplay update="slidedown" initial="block:activationsProgress">
<div class="progressivedisplay">
<span class="text">activations has ${dright.activations.size()} items <br /></span>
<span t:type="pace/grid/ActivationGrid" activationSource="dright.activations">Grid here</span>
</div>
</t:progressivedisplay>
</t:block>
<t:block id="activationsProgress">
<img class="loader" src="${context:img/ajax-loader.gif}" /> Loading activations
</t:block>
The grid appears, but clicks in the grid run into the $T(null) error above.
Looking at the XHR stuff that went back and forth in the latest version of Safari, it all looks ok, but as I said, it fails with $T(null).
No custom Javascript.
