Bug 24594 – PolicyDelegate NavigationAction is WebNavigationTypeOther instead of WebNavigationTypeReload

• Component: Page Loading
• Status: RESOLVED FIXED

[Greg Bolsinga]

FrameLoaderClient::dispatchDecidePolicyForNavigationAction() always called w/ NavigationAction::type() == NavigationTypeOther

This causes policy delegates to not be able to determine the action type.

It appears that this comes from the code path FrameLoader::loadWithDocumentLoader(), when not scrolling to an anchor. In this code path, the DocumentLoader::triggeringAction().isEmpty is true, and this is where the 'other' comes from.

Add the following patch to the MiniBrowser project. You'll see that the WebActionNavigationTypeKey is always 5, which is WebNavigationTypeOther.
