Subject [jira] Commented: (COCOON-1811) [PATCH] Flow Script: Allow dynamic loading of JavaScript objects even when scope is locked
Date Sun, 09 Apr 2006 12:10:24 GMT
    [ http://issues.apache.org/jira/browse/COCOON-1811?page=comments#action_12373770 ] 

Rob Berens commented on COCOON-1811:
------------------------------------

In the original patch FOM_JavaScriptInterpreter.txt there was a parenthesis misplaced. I therefore
added the new patch 20060409-cocoon-forms-1811. Please use the latter.

> Currently it is not possible to add variables to the scope of a FOM_JavaScriptInterpreter,
unless the scope is not locked yet or when still in the main loading process or when loading
native java classes. Therefore it is not possible to dynamically load JavaScript classes like
the one below:.
> -------------------------------
> function myObject() {                // at this point the current
> implementation throws the exception
>      // constructor for myObject
> }
> myObject.prototype.myMethod = function() {
>     // implementation of myMethod
> }
> -------------------------------
> from within a script fragment like this one:
> -------------------------------
> function loadScript() {
>     var scriptURI = "determineScriptURIFromRequest";
>     cocoon.load(scriptURI);
> }
> -------------------------------
> The attached patch solves this by allowing also objects of the type org.mozilla.javascript.Function
to be loaded into a locked scope.
