Newbie T4 Javascript question

[Jorge Quiroga <jq...@pctltda.com>]

Hello:

I'm newbie with T4 and I'm trying to do a component that is composed by 
a Checkbox, Label, A dynamic input control (could be a text, validtext, 
a checkbox or a combo) and a button.

The checkbox if is present, enable/disabled via javascript the button 
and the dynamic input control. By now the component generates the 
Javascript but when the component is called by a For then I don't know 
how to obtain the function name corresponding in the HTML code (to 
control the enabled disabled via on focus over the dynamic component and 
the by the enabled informal parameter of the button) and the T4 
documentation and the Tapestry in action book doesn´t spotlight for this 
case.

The .script involved part is:

<script>

<input-symbol key="check" class="org.apache.tapestry.form.Checkbox" 
required="no"/>

<set key="chkName" expression="check.name"/>

<let key="ctrlEnabled" unique="yes">
   enableCtrlChecked_${chkName}
</let>

<let key="CheckCheckBox" unique="yes">
   isCheckChecked_${chkName}
</let>

<body>
<if expression="not (chkName==null)">
<![CDATA[	
function ${CheckCheckBox}()
{
   if (!${chkName}.checked)
     ${chkName}.focus()
}

function ${ctrlEnabled}()
{
   if (${chkName}.checked)
     return true;
   else return false;
}
]]>
</if>
</body>

</script>

and the HTML into the component is:

<table border="1" cellspacing="0">
<tr>
<td>
   <span jwcid="@If" condition="ognl:showCheckbox">
     <span jwcid="enableCtrl@Checkbox" value="ognl:checkEnabled"/>
   </span>
   <span class="labelClass" jwcid="@Insert" value="ognl:displayName"/>
</td>
   <div jwcid="comp@RenderBlock" block="ognl:inputType"/>
     <block jwcid="alfanumeric@Block">
       <td>
         <span jwcid="alfa@TextField" value="ognl:valor" 
size="ognl:inputSize" onfocus="HOW_I_CAN_DO_IT"/>
       </td>
       <span jwcid="@If" condition="ognl:showButton">
         <td>
           <input type="button" jwcid="@Any" value="..." onClick='return 
nwl_popWindow(+dialogURL+","+dialogWidth+","+dialogHeight+","+dialogCentered+","+dialogFeatures+","+dialogTitle+");"' 
enabled='HOW_I_CAN_DO_IT'/>
         </td>
       </span>
     </block>
... other blocks
</tr>
</table>
<span jwcid="@If" condition="ognl:showCheckbox">
   <span jwcid="@Script" script="CheckedLookupDialog.script" 
check="ognl:components.enableCtrl"/>
</span>
<span jwcid="@Else">
   <span jwcid="@Script" script="CheckedLookupDialog.script"/>
</span>


I have too problems with escaping " and ' with the OnClick on the button

Thanks for your time.
