Reported 2012-06-22 06:15:24 PDT

document.getItems(typeNames) should return all Microdata top level items if there are no typeNames specified in the aurgument i.e, document.getItems(). Failing test cases: fast/dom/MicroData/007.html fast/dom/MicroData/009.html fast/dom/MicroData/002.html fast/dom/MicroData/003.html fast/dom/MicroData/properties-collection-must-see-the-properties-added-in-itemref.html In case of documet.getItem() typeNames will be null string. Earlier we used to create MicroDataItemList with m_typeNames = null string. And we used to create an unique string identifier (http://webkit.org/microdata/undefinedItemType) to map such request in the cache. With r120979 this change it creates MicroDataItemList with m_typeNames = "http://webkit.org/microdata/undefinedItemType", when typeNames argument is not specified. So we need to modify the check in nodeMatches() accordingly.

Comment on attachment 149062 [details] Updated patch Do we have a regression test that covers this? If not, can we add a new test that shows the bug?

So we need to use ownerNode() as m_ownerNode private to DynamicNodeList. Made changes accordingly.
