DBModeler to Gorm drag&drop problem

[Lars Sonchocky-Helldorf]

Hi,

I am currently in the process of preparing a live-demo of DBModeler,  
Gorm and ProjectCenter for FOSDEM similar to what Matt Rice did in  
his videos.


For that purpose I installed Ubuntu 8.10 inside a SUN VirtualBox VM.  
My aim doing so is to show how easy it is to start developing with  
GNUstep. For the same reason I got GNUstep and the dev-tools  
installed by the services that Ubuntu provides. As you might know  
this is not the latest and greatest of GNUstep but it works (somewhat).


One of the things that don't work seems to be drag and drop from  
DBModeler to Gorm. I think I got everything needed installed and  
activated: DBModeler, Gorm, the GDL2.palette. When I drag an entity  
or an relation from DBModeler into the instances-window (is it called  
that way?) of Gorm the mouse cursor changes to a small forbidden-sign.

When I now try to drop the entity or relationship snaps back into its  
place in the DBModeler Window. I tried several modifier keys: shift,  
control, alt (causes the whole window to move), command (shows the  
menu at the mouse position), nothing worked so far.


Am I missing something?

What could be the cause for this? Incompatible versions of DBModeler,  
Gorm and the GDL2.palette (I got some funky version 0.0.0(alpha) of  
DBModeler of 2006 (or was the info panel not updated), version 1.2.2  
(Release) of Gorm of 5th of November 2007 and an unknown version of  
the GDL2.palette (how do I find out the version here?))?

Is it maybe Gnome which interferes with GNUstep here? I also tried  
Window Maker what didn't help the cause a bit. What else could I try?


And my final question: Is there alternative way of getting the GDL2  
stuff from DBModeler inside Gorm? Otherwise this would possibly bust  
my talk since I don't have that much time left to track down that issue.



Thanks,

        Lars
