Bug 2345 [Editor Mgmt] Open with a different type of editor has no effect if file already open (1GEWMSQ)
Reproduce the steps in: 1GEWMOZ: ITPUI:WIN2000 - Scripted resource editor example opens on XML files by default - new basic project - new file test.xml - the editor used is the scripted resource editor example, which totally ignores the XML file content - select test.xml in Navigator - choose Open With... / Default Text Editor - nothing happens; it's reactivating the scripted resource editor example Searching for an existing open file should also consider editor types. It should open a new editor on the file, because the editor type is different. NOTES:
