Description

To reproduce...

(1) Start wookie in standalone mode
(2) Go to http://localhost:8080/wookie - (problem is with IE8 only)
(3) Click 'view widget gallery'
(4) Choose the 'sharedraw' widget

The sharedraw widget has fallback behaviour to tell the user that it won't work in IE8 (This appears as text in the actual widget)

'Unfortunately, your browser is currently unsupported by this widget...Please use of the supported browsers listed below....'

This seems acceptable behaviour, except that a javascript alert box also appears...

'Error: no canvas.getContext!'

This is almost the same as WOOKIE-158, except that in addition to this IE also reports a second error...

Line: 94
Error: 'context' is null or not an object (WOOKIE-158 doesn't report the second error)

It would seem that it is related however.
