Hello, We have an app that in turn loads subApps into Iframes. We are now attempting to minify the entire project, but of course the builder is not picking up the classes loaded from the iframe. It looks like the builder uses Ext.Loader.history to get the list of classes to include in the jsb3 file. To make it simple, when our subApp has finished loading, I was going to merge the classes from the subApp with the classes from the mainApp into Ext.Loader.history, that way the SDK will pick up all the class names. The thing that I cant figure out is when does JSBuilder stop collecting class names for the jsb3?
