No OPTION Tags rendered for PropertySelection after updateComponents
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=3D"@Shell" title=3D"Test" debugEnabled=3D"false">
<head>
</head>
<body jwcid=3D"@Body">
<form jwcid=3D"@Form" id=3D"testForm">
<a href=3D"" jwcid=3D"change">change</a>
<select jwcid=3D"selection"></select>
</form>
</body>
</html>
Page:
<page-specification>
<property name=3D"testArray" initial-value=3D'new java.lang.String[]
{"A","B","C"}'/>
<component id=3D"change" type=3D"DirectLink">
<binding name=3D"listener" value=3D"listener:onChange"/>
<binding name=3D"async" value=3D"true"/>
<binding name=3D"updateComponents"
value=3D"ognl:{'selection'}"/>
</component>
<component id=3D"selection" type=3D"PropertySelection">
<binding name=3D"model" value=3D"model"/>
<binding name=3D"value" value=3D"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=3D"selection" id=3D"selection">
<option value=3D"0">A</option>
<option value=3D"1">B</option>
<option value=3D"2">C</option>
</select>
...
But after the DirectLink is triggered, something went wrong:
...
<select name=3D"selection" id=3D"selection">1234</select>
...
No OPTION Tags were rendered.

Re: No OPTION Tags rendered for PropertySelection after updateComponents

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="refresh@Any"><select jwcid="selection"/></span> and pass the span
for update. No idea if it'll help, but just something to try.

Re: No OPTION Tags rendered for PropertySelection after updateComponents
Posted by Marcus Schulte <et...@googlemail.com>.
don't know, what's exactly wrong, but:
- the id-attribute in the form-tag is suspicious. That's normally a
reserved parameter, you should get an error.
- where do you see the 1234 without the option-tags? in the dom-tree after
the request? or in the debug output in the browser?
- if you didn't do that already, try enabling client-side debug by setting
debugEnabled=true in the Shell component.
- In which Browser are you seeing this?
