About PRWidgets

[Martial Boniou]

Thank you Lukas but that was what I actually did. I detail here with
component has i-var:

MyWAComponent>>#initialize
	component ifNil: [component := PRTocWidget new]
MyWAComponent>>#children
	^ Array with: component
MyWAComponent>>#renderContentOn: html
	html render: component

And it works well when it's PRTocWidget but not when this is
PRTreeWidget or any other PRWidget instances with class descriptions.
