[PATCH] Flow Script: Allow dynamic loading of JavaScript objects even when scope is locked
------------------------------------------------------------------------------------------

         Key: COCOON-1811
         URL: http://issues.apache.org/jira/browse/COCOON-1811
     Project: Cocoon
        Type: Improvement
  Components: Blocks: Forms  
    Versions: 2.2-dev (Current SVN), 2.1.9-dev (current SVN)    
    Reporter: Rob Berens
    Priority: Minor
 Attachments: FOM_JavaScriptInterpreter.txt

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.
