As per the documentation I can see that cq:isContainer is of type String. Even the latest carousel in the core component is also having this property. I created a proxy component in my project and tried to add this property but the crxde lite is not allowing(expecting type Boolean). I know either I can copy that property and paste it here or directly export this from eclipse. But why it is not supporting this Crxde lite. Does this need any update on Crxde in future?
