JNI Error, table overflow Max 512 - org.appcelerator.titanium.proxy.RProxy

Hey Folks,

I'm developing an app that contains various windows such as news, on-demand, tv guide etcetera.

When opening the news page you have a list view with sections for each news category, containing each 1 highlighted item and 3 other items.

When you click on an item it opens a scrollable view, containing the items including others up to a max of 15 views in the scrollable view.

When opening and closing this scrollable view like five times, I get the following error.

[ERROR] :  dalvikvm: JNI ERROR (app bug): local reference table overflow (max=512)

What I always do when closing these scrollable views, and that's what I'm doing throughout the whole application, is add a custom 'destroy:self' event to the top container of the view, like top of the tree in an alloy view.

For example for the scrollable view I do the following:

// The scrollableview is $.items
function destroySelf(e) {
    $.items.removeEventListener("destroy:self", destroySelf);
    var views = $.items.getViews();
    for(var v in views) {
        var view = views[v];
        view.removeAllChildren();
        $.items.removeView(view);
    }
    $.items = views = view = v = null;
    $.destroy();    
};
$.items.addEventListener("destroy:self", destroySelf);

This is to keep the references table low, remove views correctly, and improve performance.

Is there any reason why I get this error, containg 502 entries of org.appcelerator.titanium.proxy.RProxy?
