Dynamic JavaScript
I am currently involved in porting a Tapestry 4 project to Tapestry 5.
I came across some html with the following:
<span jwcid="@Script" script="MultiLanguageTextField.script"
inputFieldID="languageTextField"
hiddenFieldID="encodedValues"
languageSelectID="languageSelect"/>
I've been told that this is for dynamic JavaScript. I haven't been able
to find documentation for how this is done in Tapestry 5. Could someone
point me to a good Url that explains this.
Thank you.

No, the strategy has changed. You generally want to
a) Include a static JavaScript file with the logic (event handlers, etc.)
b) Generate a *small* amount of initialization JavaScript dynamically
Because statics are only included once, you no longer need the
<unique> element from the T4 script DTD.
Initialization code is generated in code, using the RenderSupport environmental.
T4 tried to merge both these concepts into the script DTD.

Does Tapestry 5 still use the following type of script file or has this
changed? I couldn't tell from browsing through the Url you gave.
<!DOCTYPE script PUBLIC
"-//Apache Software Foundation//Tapestry Script Specification 3.0//EN"
"http://jakarta.apache.org/tapestry/dtd/Script_3_0.dtd">
<script>
<input-symbol key="inputFieldID" class="java.lang.String"
required="yes"/>
<let key="inputFieldPath">
document.getElementById("${inputFieldID}")
</let>
<body>
<unique>
<![CDATA[
function updateInputField()
{
var inputField = ${inputFieldPath};
.
.
.
