Howard M. Lewis Ship closed TAPESTRY-2394.
------------------------------------------
Resolution: Invalid
Assignee: Howard M. Lewis Ship
This is by design, to decrease the amount of markup sent to the client (in this
case, all those id attributes). If you need to ensure that your components
render a unique id, then you need to inject them and invoke getClientId().
Alternately, you could create a mixin to invoke getClientId() (that's a better
solution, in fact).
> clientid not rendered for pagelink or actionlink (with no zone parameter)

> Key: TAPESTRY-2394
> URL: https://issues.apache.org/jira/browse/TAPESTRY-2394
> Project: Tapestry
> Issue Type: Bug
> Components: Core Components
> Affects Versions: 5.0.12
> Environment: Any
> Reporter: Steven Woolley
> Assignee: Howard M. Lewis Ship
>
> the clientid is no longer rendered for pagelinks or actionlinks. The cause
> (from walking through the debugger) is this:
> For actionlinks:
> when there is no zone parameter, the call to getClientId() on the actionlink
> is never made, and thus the clientid is never rendered. Pagelink's simply
> never make a call to getClientId().
> This line in AbstractComponentEventLink's beginrender hilights the issue
> culprit:
> if (_zone != null) _clientBehaviorSupport.linkZone(getClientId(), _zone);
> For pagelinks, there is simply no call to getClientId() anywhere in its
> rendering.
> I just double checked, very latest snapshot from maven:
> http://tapestry.formos.com/maven-snapshot-repository//org/apache/tapestry/tapestry-core/5.0.12-SNAPSHOT/tapestry-core-5.0.12-20080428.110035-48.jar
> Test.java:
> package org.example.myapp.pages;
> public class Test {
> }
> Test.tml:
> <html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
> <head><title>test</title></head>
> <body>
> <a t:id="addSongsToList" t:type="actionlink" ></a>
> </body>
> </html>
> renders:
> <html><head><link href="assets/tapestry/5.0.12-SNAPSHOT/default.css"
> rel="stylesheet" type="text/css"><title>test</title></head><body><a
> href="test.addsongstolist"></a></body></html>
> Same thing in a loop renders:
> <html><head><link href="assets/tapestry/5.0.12-SNAPSHOT/default.css"
> rel="stylesheet" type="text/css"><title>test</title></head><body><a
> href="test.addsongstolist"></a><a href="test.addsongstolist"></a><a
> href="test.addsongstolist"></a></body></html>
> And if I explicitly set the id="something":
> <html><head><link href="assets/tapestry/5.0.12-SNAPSHOT/default.css"
> rel="stylesheet" type="text/css"><title>test</title></head><body><a
> href="test.addsongstolist" id="something"></a><a href="test.addsongstolist"
> id="something"></a><a href="test.addsongstolist"
> id="something"></a></body></html>
> Also double checked in 5.0.11 and it works as expected:
> Test.tml:
> <html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
> <head><title>test</title></head>
> <body>
> <t:loop source="1..3">
> <a t:id="addSongsToList" t:type="actionlink" ></a>
> </t:loop>
> </body>
> </html>
> renders:
> <html><head><link href="assets/tapestry/default.css" rel="stylesheet"
> type="text/css"><title>test</title></head><body><a href="test.addsongstolist"
> id="addSongsToList"></a><a href="test.addsongstolist"
> id="addSongsToList_0"></a><a href="test.addsongstolist"
> id="addSongsToList_1"></a></body></html>
