Mouse click gets wrong coordinates in the Scrollviews document view after autoscroll to a textfield outside the scrollviews visible rect.

I'm setting up a scrollview in the window that autosizes to the windows rect. In the document view I set up some textfields that are connected with the nextKeyView outlet. If sizing the window smaller than the document view and then using the tab key to tab to a textfield outside of of the scrollview's visible rect, making the scrollview autoscroll to that textfield, the hit point when clicking in the scrollview gets wrong coordinates. The coordinates given is not scrolled in the document views coordinate system. If clicking in the top left corner the hit point returned is the top left corner of the document view. The offset scrolled in not added.

I have made a little test app on the url and it is called KeyViewTest.

An easy way to see the bug is to start the application,
1) make the browser's window so small it only shows the popup button and two of the textfields,
2) then click in the first textfield (no 1) and using the tab-key go down to the fourth textfield (no 4).
3) Now click with the mouse on the top visible textfield (no 2) and the popup buttons items will show up.

The MainMenu.xib file can be found in

I have no fixes for this issue, sorry.

This is tested in MacOSX 10.8.1, using all kinds of browser Standard Safari, Webkit Safari, Crome, Firefox and Opera, all latest versions. Cappuccino version used is 0.9.6-RC2. XCode used is 4.4.1.

I cant see any other issue that informs about this behavior but it may have relations to an issue called
'CPScrollView adjusts documentView's origin incorrectly on CPScrollView resize'.

@mrcarlberg mrcarlberg Make sure the text field is visible before focus so the browser
will not scroll without the NSScrollView knowing about it

This fix will not work without pull

@kerusan could you make a download of your test application available? Thanks.

I'm also going to close this as a duplicate of #1679.
