Rendering of blocks and/or zones
--------------------------------
Key: TAPESTRY-2132
URL: https://issues.apache.org/jira/browse/TAPESTRY-2132
Project: Tapestry
Issue Type: Improvement
Affects Versions: 5.0.10
Reporter: Igor Drobiazko
Initially a block is not rendered. This is quite reasonable for the usecase in
which you define an empty block for the Grid.
Now consider following scenario:
We have a Grid containing an ActionLink for every single row.
<t:grid t:id="grid" source="users" model="model" row="user">
<t:parameter name="deleteCell">
<t:actionlink t:id="delete" zone="deleteZone"
context="user.id">Delete</t:actionlink>
</t:parameter>
</t:grid>
Clicking on the link I want to delete the user and update the table without to
refresh the whole page.
To make a partial response we have several possibilities. Two of them are to
return a component or a block.
It would be nice to wrap the table by a block which is rendered initially. This
block could be returned by the action method.
Alternatively one could put the Grid into the zone but this doesn't work well.
Every second click ends in a full refresh of the page.
The reason is that after the partial response the ActionLinks of the updated
Grid are not converted into Ajax links.
