Hi Andrey, Great! If you can give me a example for,
collection.onChange(element) it will be highly appreciated. @Maxim, After some thinking I cam across of this idea. Please correct me If I am wrong. - All the whiteboard elements can be represented as JSON strings (Have to find a way to add PDF,DOCs, Pictures to whiteboard in this way) - At the Wicket Java code we save these elements as Java Objecst which contains the JSON strings. - To synchronize white board we can send these object to all the viewers. - To save/load we can use this already implemented JSON based serialization and de-serialization. But have to find ways to get all these data from closure implementation to wicket! Thanks!
