User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:13.0) Gecko/20100101 Firefox/13.0
Build ID: 20120531155942

Steps to reproduce:

Run a test case with AccProbe

http://www.aisquared.com/testdocs/Aria/AriaInvalid.html 


Actual results:

aria-invalid is not exposed as text attribute


Expected results:

aria-invalid should be exposed as text attribute

Comment 1

[Jost Eckhardt, Ai Squared]

Sorry, I got it mixed up. The aria-invalid is an existing issue: 445510

this is about aria-orientation

aria-orientation should be mapped to IA2_STATE_HORIZONTAL

The test case is: http://www.aisquared.com/testdocs/Aria/AriaOrientation.html

I see that aria-orientation="vertical" are mapped to vertical and horizontal states which is a bug. Bug as far as I can see by accprobe aria-orientation="horizontal" is mapped to horizontal state. Can you give me exact steps to reproduce please?

Comment 3

[Alex Kulikov, Ai Squared]

Accordingly to the spec(http://www.w3.org/TR/wai-aria-implementation/#mapping_state-property_table) user agents must set IA2_STATE_HORIZONTAL attribute if aria-orientation="horizontal" and clear it if aria-orientation="vertical" (aria-orientation="vertical" is not mapped to the IA2_STATE_VERTICAL). 
Steps to repro:
a)Test case #1 (http://www.aisquared.com/testdocs/Aria/AriaOrientation.html) presents three items that have vertical orientation (aria-orientation="vertical"), but AccProbe reports the following states: [vertical, ...., horizontal];
b)Test case #3  (http://www.aisquared.com/testdocs/Aria/AriaOrientation.html) presents an ARIA scrollbar that have no aria-orientation attribute defined. AccProbe reports that the orientation of the item is set to horizontal (IA2_STATE_HORIZONTAL is set), but, accordingly to the spec., aria-orientation="vertical" is a default orientation for an aria scroll bar.

Thanks, Alex, that's what I observe. Can you fix bug summary then?

Comment 5

[David Bolter [:davidb]]

Looks like a regression from bug 741398 but I don't know how our mochitest passes.

Aha.

Comment 7

[David Bolter [:davidb]]

I'm a little nervous that we rely on memory alignment for the mValues (when calling FindAttrValueIn in our state map code).

why? I'm pretty sure the spec says that's legit.

Trevor can you take this one?

these tests were cheked in doing this with no reason given.  It doesn't seem terribly useful to say links are "horizontal", so I'm proposing we just change them.

If removing this state from links is wrong, I don't want to be right. r=me.

I'm not sure what you mean all this function has access to is the eStateRule, perhaps we should pase more, but currently we don't

no idea, I think it was because bz said just IsXUL() was wrong and suggested that.

each entry has an option of default state, see http://mxr.mozilla.org/mozilla-central/source/accessible/src/base/nsARIAMap.cpp#413

if you do follow up then please fix it as well.

in either way you put it under IsXUL() what could make bz comment irrelevant (in case if IsBoxFrame() returns true for some HTML).

true, but that doesn't quiet work because at some point you need to clear the default state if the non default state is set explicitly.

nsXULLabelFrame?

I meant, stuffs like GetRoleMap(aElement)->Is(nsGkAtoms::scrollbar) should be replaced by default state.
