Thanks Esteban,
In the playground:
----
| header |
header := VIHeaderComponent new.
header rendererClass.
----
Returns: WAHtmlCanvas and not SBSHtmlCanvas.
----
Thus the fix was to override rendererClass and return the correct rendering
class.
Nowhere in the documentation is this evident (although if I was ST proficient I
would have been able to figure that out?
Thanks Muchly Esteban!!
