RegisterDoubleClickHandler overwrites

[Brian Klug]

Problem: When you call RegisterDoubleClickHandler for a certain tag, i.e. IMG, the new handler will overwrite the old one in all cases. Desired behavior: Both old and new handlers will get called.

Example: Let's say you have a handler that checks to see if the IMG tag is of class "x". If so, it will alert(1) when you click on an image with CSS class of "x". But if you register a new handler for IMG, say for example one that is for class of "y" - this will overwrite the handler for IMG's with class "x" and the alert will not get called.

Proposed patch:

Replace the existing RegisterDoubleClickHandler with this function:

// Register objects that can handle double click operations.
FCK.RegisterDoubleClickHandler = function( handlerFunction, tag )
{
  if (FCK.RegisteredDoubleClickHandlers[tag.toUpperCase()])
  {
    var oldfunction = FCK.RegisteredDoubleClickHandlers[ tag.toUpperCase() ];
    FCK.RegisteredDoubleClickHandlers[ tag.toUpperCase() ] = function(arg)
    {
      oldfunction(arg);
      handlerFunction(arg);
    }
    return;
  }
  FCK.RegisteredDoubleClickHandlers[ tag.toUpperCase() ] = handlerFunction;
}
