| [gef-dev] Exception bendpoiints in 3.0 |
|
Hi, I have build an activity diagram modeller with GEF2.1
and would like to transport everything to 3.0 (Eclipse3.0/GEF3.0). Everything
seems to run as designed, but if I try to choose a connection in my modellerView
I get the following exception: !ENTRY org.eclipse.ui 4 0 Jul 08, 2004 10:40:32.891 !MESSAGE java.lang.NullPointerException !STACK 0 java.lang.NullPointerException at
