I see two things off the top:
- DirectLink won't rewind the form. You should really be using
LinkSubmit if you want to capture the selected value.
- The updateComponents property of the DirectLink might work, but it's
not guaranteed if you have multiple instances of this component or a
name collision. The good way to pass a component to this list is with
"components.selection.clientId" rather than hardcoding the name.
I don't think either of these problems should be causing the breakage
you're seeing. One thing to try would be to wrap "selection" in a <span
jwcid="[EMAIL PROTECTED]"><select jwcid="selection"/></span> and pass the span
for update. No idea if it'll help, but just something to try.

Hy there...
its my first post on this list and I haven't found anything regarding my
actual Tapestry 4.1.2 Problem.
See the example below.
HTML-Template:
<html jwcid="@Shell" title="Test" debugEnabled="false">
<head>
</head>
<body jwcid="@Body">
<form jwcid="@Form" id="testForm">
<a href="" jwcid="change">change</a>
<select jwcid="selection"></select>
</form>
</body>
</html>
Page:
<page-specification>
<property name="testArray" initial-value='new java.lang.String[]
{"A","B","C"}'/>
<component id="change" type="DirectLink">
<binding name="listener" value="listener:onChange"/>
<binding name="async" value="true"/>
<binding name="updateComponents"
value="ognl:{'selection'}"/>
</component>
<component id="selection" type="PropertySelection">
<binding name="model" value="model"/>
<binding name="value" value="name"/>
</component>
</page-specification>
Java:
public abstract class Test extends BasePage {
public abstract String[] getTestArray();
public abstract void setTestArray(String[] testArray);
public IPropertySelectionModel getModel() {
return new StringPropertySelectionModel(getTestArray());
}
public void onChange() {
setTestArray(new String[]{"1","2","3","4"});
}
}
The test consists of a DirectLink Component and a PropertySelection.
The PropertySelection is initialized with a StringPropertySelectionModel
and should change its options when the DirectLink is clicked.
The first call of the Page shows that the PropertySelection is working:
...
<select name="selection" id="selection">
<option value="0">A</option>
<option value="1">B</option>
<option value="2">C</option>
</select>
...
But after the DirectLink is triggered, something went wrong:
...
<select name="selection" id="selection">1234</select>
...
No OPTION Tags were rendered.
