incorrect zone id javascript mapping with page having more than 1 of same
component containing a zone
------------------------------------------------------------------------------------------------------
Key: TAPESTRY-2472
URL: https://issues.apache.org/jira/browse/TAPESTRY-2472
Project: Tapestry
Issue Type: Bug
Components: Core Components, JavaScript, tapestry-core
Affects Versions: 5.0.13, 5.0.14
Environment: jetty 6.1.9, java 1.6, os x, linux
Reporter: Mike Oestereter
When a page contains more than one of the same component (either multiple
inclusions or inside a loop) and the component contains a zone with an
actionlink that updates this zone then only the zone of the first component
instance gets updated in all actionlink-clicks of all components.
It appears as if the Tapestry javascript initialization mapping parameters are
incorrect:
This is what gets generated:
Tapestry.DEBUG_ENABLED = true;
Tapestry.onDOMLoaded(function() {
Tapestry.init({"zone":["zone1","zone1_0"],"linkZone":[["update","zone1"],["update_0","zone1"]]});
});
It should be:
...
Tapestry.init({"zone":["zone1","zone1_0"],"linkZone":[["update","zone1"],["update_0","zone1_0"]]});
...
Below is more detailed information including code examples:
I get the correct result after clicking on
the "update: two" hyprlink (the correct zone is updated):
update: one (hyperlink)
UPDATED two
BUT when I modify the page .tml and put the body inside a
<html><body>...</body></html> in stead of only inside a
<html>...</htm>
The following html source get generated by tapestry at the bottom of
the page and...
<!--
Tapestry.DEBUG_ENABLED = true;
Tapestry.onDOMLoaded(function() {
Tapestry.init({"zone":["zone1","zone1_0"],"linkZone":[["update","zone1"],["update_0","zone1"]]});
});
// -->
...and the result is incorrect ("zone1_0" should have been updated and
not "zone1"):
UPDATED two
update: two (hyperlink)
Here is all the code:
Page code:
ZonePage.tml
<html xmlns:t = "http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
<t:zonecomp>one</t:zonecomp>
<br/>
<t:zonecomp>two</t:zonecomp>
</html>
public class ZonePage {
}
Component Code:
ZoneComp.tml
<t:container xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
<t:zone t:id="zone1" visible="true">
<t:delegate to="prop:activeBlock"/>
</t:zone>
<t:block t:id="beforeUpdate">
<t:actionlink t:id="update" zone="zone1">update:
<t:body/></t:actionlink>
</t:block>
<t:block t:id="afterUpdate">
<p>UPDATED <t:body/></p>
</t:block>
</t:container>
public class ZoneComp {
@Persist("session")
private boolean updated = false;
@Inject
private Block beforeUpdate;
@Inject
private Block afterUpdate;
@Component(id="zone1")
private Zone zone;
public Object onActionFromUpdate() {
updated = true;
return zone;
}
public Object getActiveBlock() {
if (updated) return afterUpdate;
return beforeUpdate;
}
}
