Thanks, Anthony!

It is nice to hear that someone else has thought about the same issue and in fact has come to the same conclusion.

I already realized the weakness of the Observable that the 2 communicating modules must be in the same scope, which is at time troublesome and have also read up on the MsgBus and Mediator (pub/sub) ideas.

I think, I will give those last ones a stab.


And as far as the module instance goes, I do have more going on than the trimmed version above, namely:

<script type='text/javascript'>

    var initOpenCytoPreprocessing = function(){
        var webPartDiv = <%=webpartContext%>.wrapperDivId;

        var resizeModule;
        var OpenCytoPreprocessing = new LABKEY.ext.OpenCytoPreprocessing({
            webPartDivId: webPartDiv
        });

            captureEvents( OpenCytoPreprocessing );

        resizeModule = function(w, h){

            LABKEY.Utils.resizeToViewport( OpenCytoPreprocessing, w, -1, null, null, -5 );

            OpenCytoPreprocessing.resize();
        };

        Ext.EventManager.onWindowResize( resizeModule );
        Ext.EventManager.fireWindowResize();

    }

    Ext.onReady( initOpenCytoPreprocessing );

</script>
