---------------------------
Summary: 5.4-alpha-2 - Delegate in eventlink body prevents ajax
Key: TAP5-2060
URL: https://issues.apache.org/jira/browse/TAP5-2060
Project: Tapestry 5
Issue Type: Bug
Components: tapestry-core
Affects Versions: 5.4
Reporter: Lance
I have found a bug in 5.4-alpha-2 which does NOT occur in 5.3.6 when using the
exact same code. The symptoms of the bug are:
1. I have a component parameter, "linkBody", which is a block
2. I delegate to the "linkBody" in the body of an ajax eventlink
3. When the "linkBody" parameter contains markup, the serverside event is NOT
XHR as expected
4. When the "linkBody" does not contain markup (a simple string), the
serverside event is XHR as expected
5. There are no javascript errors shown in the browser (firefox and chrome)
6. This happens for both prototype and jquery
The component (below) succeeds for the following tml:
=========================================
<t:myComponent>
<p:linkBody>This is a plain text link body</p:linkBody>
</t:myComponent>
The component (below) throws a "NOT XHR" exception for the following tml:
=======================================================
<t:myComponent>
<p:linkBody><div>This link body contains markup</div></p:linkBody>
</t:myComponent>
MyComponent.tml
=============
<div xmlns:t="http://tapestry.apache.org/schema/tapestry_5_3.xsd";
xmlns:p="tapestry:parameter">
<t:zone t:id="myZone" />
<t:eventlink event="doIt" zone="myZone">
<t:delegate to="linkBody" />
</t:eventlink>
<t:block t:id="ajaxBlock">
Hello World
</t:block>
</div>
MyComponent.java
==============
public class MyComponent {
@Parameter(required=true)
@Property
private Block linkBody;
@Inject
private Block ajaxBlock;
@Inject
private Request request;
Block onDoIt() {
if (!request.isXHR()) {
throw new RuntimeException("Request is not XHR");
}
return ajaxBlock;
}
}
