Write is as:
private String alert = "document.jsAlert = function () { alert(\"HELLO\"); }";Because tapestry includes such initialization in Tapestry.onDOMLoaded( ... ) the scope of jsAlert (in your original version) is not the current document but an anonymous function - and it is lost after the function exits. So, just attach it to the document and it'll be there when you call it.
