no, no, it's surely not the expression syntax you need to use. This
would be evaluated in the Faces-Subsystem, not by JavaScript.
I wonder from your expression what you want to achieve - you'll need
to set something to a destElem for the listener to make sense.
In any case, your original string was correct, obviously it doesn't
make any sense with the rest of your component tree, though.
Fire up your JavaScript debugger and step into
JSListener.js
function orgApacheMyfacesJsListenerSetExpressionProperty(
srcId, destId, property, expression)
{
to find out what happens.
