Note: it is perfectly valid start a drag then drop the view back where it came from... however, you are correct in pointing out that the user should never see the arrow icons or associated split rectangles for a drop that results in a NOP. Both issues fixed in head. |
I200403240800, close all perspectives, new java perspective. select outline view. drag tab to bottom edge of outline view. notice down arrow and tracking rect over bottom half of view. this was to be the subject of my bug which i had noticed a number of times previously, as this should never occur considering the outline view is not part of a stack. in this particular case however, the drop causes the outline view to disappear and the following occurs in the .log: !SESSION Mar 24, 2004 14:40:08.509 ---------------------------------------------java.version=1.4.2_03 java.vendor=Sun Microsystems Inc.
