>>>>>>>>>>>>> >>>>>>>>>>> improvements and integration of your Whiteboard to
>>>>>>>>>>>>> wicket. I have looked at
>>>>>>>>>>>>> >>>>>>>>>>> your code which can be found
>>>>>>>>>>>>> https://github.com/bay73/whiteboard . I
>>>>>>>>>>>>> >>>>>>>>>>> have following questions,
>>>>>>>>>>>>> >>>>>>>>>>>
>>>>>>>>>>>>> >>>>>>>>>>> - In Wicket, I want map Whiteboard
>>>>>>>>>>>>> Elements(Rectangle, Circle,
>>>>>>>>>>>>> >>>>>>>>>>> Text, etc.) to Java objects.
>>>>>>>>>>>>> >>>>>>>>>>> - Thus we can send those object to all the
>>>>>>>>>>>>> Whiteboard viewers.
>>>>>>>>>>>>> >>>>>>>>>>> - Using these objects there Whiteboards will be
>>>>>>>>>>>>> updated.
>>>>>>>>>>>>> >>>>>>>>>>> - To do that, can I get some data from your
>>>>>>>>>>>>> code? which can be
>>>>>>>>>>>>> >>>>>>>>>>> later used to create elements. I saw there is a
>>>>>>>>>>>>> serialization methods and
>>>>>>>>>>>>> >>>>>>>>>>> deserilization method in base.js. If we can
>>>>>>>>>>>>> extend that mechanism to give
>>>>>>>>>>>>> >>>>>>>>>>> some data when element is drawn or edited as an
>>>>>>>>>>>>> event, I can use them to
>>>>>>>>>>>>> >>>>>>>>>>> create Java objects.
>>>>>>>>>>>>> >>>>>>>>>>> - Also there should be a mechanism to draw
>>>>>>>>>>>>> elements on your
>>>>>>>>>>>>> >>>>>>>>>>> Whiteboard by passing those data.
>>>>>>>>>>>>> >>>>>>>>>>>
>>>>>>>>>>>>> >>>>>>>>>>> Can we do these things?
