Composit in SmartGWT ?

[halloula]

Hello,

i have a class that it's extending from composit in GWT,i'am trying to migrate it to Smart,can i let it the same extend ? or extending from Canvas will do the same job ?
in fact i already tryed it and i replaced initWidget with doInit(),and i'am having this error :

It depends on exactly how your using the widget, what type of parent does it belong to, does it have children. Better to extends from Canvas if possible, post some more information about what exactly your doing.
