Subject [jira] Commented: (ADFFACES-206) CSS 2 composite selector is not supported in MSIE 6

-----------------------------------------

Simon,
I was thinking of a way that is very similar to your #2. I rewrote your example to fit my
idea.

2) Alter CSSGenerator to use a different path for MSIE so that composite selectors get reduced
to a single selector by pair of two and add code to renderStyleClasses combine the classes
accordingly to see if it was defined in the skin.Here's a little example of that solution:

af|myComponent:state1:state2::subComponent

CSS generator first split that into 3 selectors (current behavior):
af|myComponent with states :state1 and state2
af|myComponent::subComponent

Then sort them alphabetically (will improve performance in the end, especially in renderStyleClasses):
af|myComponent:state1:state2
af|myComponent::subComponent

Notice that you cannot reorder where the state pseudo-classes are in relation to the main
selector/pseudo-elements. If you do, it totally changes the meaning of the style definition.

In the shortened stylemap, we currently do not put pseudo-classes. So we'd put af|myComponent
and af|myComponent::subComponent.

We need a method similar to renderStyleClasses, but where you know which ones are the states,
and which one is the main selector. So renderStyleClassWithStates(selector, states), and we
render all the combinations of selector-state1 selector-state2 selector-state1-state2 (with
the states being alphabetized.) If selector was shortened to x10, for example, it would be
x10-state1, x10-state2, x10-state1-state2 that we would render

> Microsoft Internet Explorer 6 does not support CSS 2 composite selectors, e.g. ".someClass.anotherClass".
However, the skinning engine uses those for states mainly. For example, af|component:myState
will be parsed to .af_component.p_AFMyState in the generated CSS and the renderer will add
both classes on the component.
> MSIE 6 only evaluate the latest class in the classe list when evaluating composite selector
which has very bad results for some component.
