Hi,
I just installed the Cascade drop 3 and try to run the redbook GEF example
NetworkModel ( chapter 5), I got the error of Unable to create part. It
works fine on the GEF 3.0.0 (05-13-2004 build or Cascade 3.0 drop 2 build.)
The problem is in lines are:
CreationToolEntry entry;
entry = new CreationToolEntry("Node", "Create a node", new
ModelCreationFactory(Node.class), null, null);
add(entry); // This line causes the exception !!!!!
The exception is in the org.eclipse.gef.palette.PaletteContainer.java:
add (int index, PaletteEntry enty) {
if (!acceptsType(entry.getType()))
throw new IllegalArgumentException(
"This container can not contain this type of child: " +
entry.getType());
List oldChildren = new ArrayList(getChildren());
...
}
I debug the same code with Cascade I2, the same add() method in I2 didn't
have the acceptsType() test, and it is simply:
add (int index, PaletteEntry enty) {
List oldChildren = new ArrayList(getChildren());
...
}
How to fix and make the code work in I3?
Best Regards,
SL

GEF 3.0.0 was released on 06-25-2004. You should have the same behavior on
both 3.0.0 and 3.0.1
The solution is to create either a group or a drawer to contain the entry.

I actually have 2 version of GEF 3.0.0 and the earlier one works but the
later one has exactly the same behavior as you mentioned. Is there a
simple example on how to create either a group or a drawer for the
pallete? Thanks.

From my reply to your previous post:
So, to fix this problem, create a group or drawer and put the tools inside
that. Look at LogicPlugin#createPalette() if you are not sure how to do
that.
