[Seaside-dev] WATagBrush>>class:if: with boolean and additional blocks

[Torsten Bergmann]

WATagBrush>>class:if: is implemented like this:


    class: aString if: aBoolean
	"Adds the class aString to the receiving element if aBoolean is true. 
	
	Example:
	
	html div
		class: 'error' if: self hasError;
		with: self errorMessage"

	aBoolean
		ifTrue: [ self class: aString ]


What about changing it to:

    class: aString if: aBooleanOrBlock
	...

	aBooleanOrBlock value
		ifTrue: [ self class: aString ]


This way one could use a boolean as before but also a conditional block coming from 
elsewhere. This change would also be backward compatible and not break existing code.

What do you think?

Thx
