Form name is null in scripts
Hi,
I have a problem with Javascript and Tapestry 2.3. On my scripts, the form
name is not rendered.
I have a script file (/somepath/myapp.script) :
----------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE script PUBLIC
"-//Howard Lewis Ship//Tapestry Script 1.2//EN"
"http://tapestry.sf.net/dtd/Script_1_2.dtd">
<script>
<include-script resource-path="/somepath/myapp.js"/>
<input-symbol key="page" required="yes"/>
<set key="formName" expression="page.form.name"/>
<set key="name" expression="page.name"/>
<!-- baseName - base name from which other names are generated -->
<let key="baseName">
${formName}_${name}
</let>
<let key="formPath">
document.${formName}
</let>
<body>
function clearCheckboxes() {
clearCheckboxes(${formPath});
}
</body>
<initialization/>
</script>
----------------------------------------------------------------------
Here is the script component in my page :
----------------------------------------------------------------------
<component id="Script" type="Script">
<static-binding name="script">/somepath/myapp.script</static-binding>
<binding name="symbols" expression="scriptSymbols"/>
</component>
----------------------------------------------------------------------
In my page class I have :
----------------------------------------------------------------------
private Map _scriptSymbols;
public MyPage() {
_scriptSymbols = new HashMap();
_scriptSymbols.put("page",this);
}
public Map getScriptSymbols() {
return _scriptSymbols;
}
public IForm getForm() {
return (IForm)getComponent("myForm");
}
----------------------------------------------------------------------
In my template, I have :
----------------------------------------------------------------------
<!-- generated by Spindle, http://spindle.sourceforge.net -->
<html>
<body>
<!-- begin of $content$ -->
<span jwcid="$content$">
<span jwcid="shell">
<body jwcid="body">
<span jwcid="Script"/>
[...]
----------------------------------------------------------------------
And when I run the page, the form name is not generated, here is what I have
:
----------------------------------------------------------------------
<script language="JavaScript" type="text/javascript"
src="/myapp?service=asset&sp=%2Fsomepath%2Fmyapp.js"></script>
<script language="JavaScript"><!--
function clearCheckboxes() {
clearCheckboxes(document.);
}
// --></script>
----------------------------------------------------------------------
As you can see, the form name is not rendered (document.). What I am doing
wrong ? I'm a bit lost.
Thanks,
Laurent CORNELIS

Hi,
Please move the script component under the form one in the template.
The form name is generated dynamically (since it can be in a loop, for
example) at the time the form is rendered. Moving the script component under
the form would resolve the issue, I believe.
