[Seaside-dev] WABuilder and Render Context

[Maximilian Bareis]

Hi Esteban,

the procedure is fine for small chunks that do not need a specific RenderContext.

I am currently developing the tests for SeasideDynamicSVG package. There is everything already developed (own Canvas etc.) but I need to move it to Seaside 3.1. For that I am adding more testcases to ensure the stability.

The decent problem for this case is, that an AnchorBrush is created related to the Context:

anchorBrush := self context disableSVGAnchors
		ifTrue: [SVGDisabledAnchorBrush new]
		ifFalse: [SVGAnchorTag new].
	^self brush: anchorBrush

So without having my own context I am not able to use the WABuilder to create a SVGDisabledAnchorTag.
I could also create a subclass SVGBuilder but I think this feature may be useful also for WABuilder.

Regards

Max
