Javascript: Jump to declaration still not at JSDT's level

Hi,
I've been stuck with Eclipse Luna for years now, because of it being (along with Mars) the last version where JSDT worked fine (syntax coloring unbroken).

Your tool seems finally to get close to JSDT in certain aspects, surpass it in others.

But really: the most useful feature in a tool like this (even more important than syntax coloring) is the Jump to declaration ! How can anyone work without it when the project becomes more and more complex ?

And WWD doesn't come close the JSDT regarding Jump to declaration. Or I'm missing something. It works in the same file, when there are prototype functions, but look at this example:

(function ()
{
var global = this || window;
var _Ctrls = null;
_Ctrls = global.Ctrls =
{
test: function()
{
//////
},
test2: function()
{
_Ctrl.test();
}
};
})

Typing F3 (Jump to declaration) on the test() call would give a message like "The operation is not applicable to the current selection etc..."
In JSDT it would take me to the test function declaration. It would even take me to it when called in another javascript file in the same project !

Can anyone tell if this a final behavior or is there a chance to fix it ?

Regards

Reproduisez l’exemple JavaScript fourni dans Eclipse et invoquez F3 sur l’appel test(). Comparez le comportement au sein d’un même fichier et entre les fichiers JavaScript d’un même projet avec le comportement de JSDT décrit. C’est terminé lorsque Jump to declaration atteint la déclaration de la fonction test au lieu d’indiquer que l’opération n’est pas applicable.
