Lose EventListener handling if you update a component containing that
EventListener target
------------------------------------------------------------------------------------------
Key: TAPESTRY-1524
URL: https://issues.apache.org/jira/browse/TAPESTRY-1524
Project: Tapestry
Issue Type: Bug
Components: XHR/dhtml/Ajax
Affects Versions: 4.1.2
Environment: java 1.5.0_07, osx 10.4.9, tomcat 5.5.24
Reporter: Julian Wood
Priority: Minor
It seems that if you update a component inside which there is another component
on which there is an EventListener, you will lose that EventListener.
For example:
<div jwcid="[EMAIL PROTECTED]">
<div id="nameHeader">Name<span jwcid="@Insert" value="ognl:sortAscending?'
^':' v'"/></div>
</div>
@InitialValue("ognl:false")
@Persist
public abstract Boolean getSortAscending();
public abstract void setSortAscending(Boolean sortAscending);
@EventListener(elements = "nameHeader", events = "onclick", async = true)
public void sort(IRequestCycle cycle)
{
setSortAscending(!getSortAscending());
cycle.getResponseBuilder().updateComponent("myTable");
}
So if you load this up in a browser, then click on 'Name v', it changes to
'Name ^' like it should. But if you click it again, it has lost it's
EventListener, and 'Name ^' doesn't change. The ajax response didn't include
this bit which creates and connects the event:
tapestry.cleanConnect(dojo.byId("nameHeader"), "onclick", "event1702620775");
tapestry.event1702620775=function(e){
var content={beventname:"onclick"};
tapestry.event.buildEventProperties(e, content);
if (!content["beventtarget.id"]) content["beventtarget.id"]="nameHeader";
tapestry.bind("/myapp/app?component=adminBillableItems&page=Admin&service=directevent&session=T",
content);
};
dojo.event.connect(dojo.byId("nameHeader"), "onclick", tapestry,
"event1702620775");});
