Value substituions don't work in the scripts of composite components

[javaserverfaces]

if you place a value like this:

var savedValue = "#

{compositeComponent.attrs.value}

";

In an inline script of a composite component, it works.

If you place it in an external script, the .js file is returned to the browser as an empty file, and the following error appears in the logs:

driscoll said: Steps to reproduce:

create a page which calls a composite component named "componentname".

Create a composite component with

Also, declare "value" in the interface.

In resources/componetname/componentname.js, place one line: var savedValue = "#

{compositeComponent.attrs.value}

"; (You can add more lines as well, just to see that the bug effects all lines.)

On page load, you'll see that the js file has a single, empty line. There is no error sent to the user, and the stack trace is as above in the logs.

I can post the exact code if this is still not clear.

@rlubke said: The null pointer exception no longer occurs in the trunk.

However, to set expectations, using #

{compositeComponent}

expressions in an external script won't work since external scripts will be requested separately from the page and as such there will be no current component (beit composite or otherwise)

driscoll said: As an aside, some of the ajax demos, (see jsf-demo/ajax-switchlist) show examples of one proper way to use separate scripts with the #

{compositeComponent}

EL. (Think of it as passing a context to the function.)
