[jira] Closed: (TAPESTRY-2472) incorrect zone id javascript mapping
with page having more than 1 of same component containing a zone
[ https://issues.apache.org/jira/browse/TAPESTRY-2472?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Howard M. Lewis Ship closed TAPESTRY-2472.
------------------------------------------
Resolution: Invalid
Assignee: Howard M. Lewis Ship
Again, assign the zone's id to a specific value. Tapestry can't do it for you because the Zone and its content may be rendered at different times and may even exist on different pages of the application.

> 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
> Assignee: Howard M. Lewis Ship

> 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() {
