[Seaside] #urlForDocument: w/o canvas?

[Sebastian Sastre]

Hi Udo,

For elegance you can make that dictionary to be in an inst var of your wrapper
component and in the render method json that instvar (presumably with a proper
dictionary). 
That way could potentially be changed in any calback and then render properly
according to that.
Make some convenience accessors and you're done,

Cheers,

Sebastian Sastre
PD: that, of course, if I understood you right ;)
