Product Version: NetBeans IDE 6.0 Beta 1 (Build 200709060000) 
Java: 1.5.0_07; Java HotSpot(TM) Client VM 1.5.0_07-87 
System: Mac OS X version 10.4.10 running on i386; MacRoman; en_US (nb)

Found on and linux for sure.

Problem:
Using refactor->move to move a schema to a subproject, the project select drop down list is greyed out.  This is
misleading because it would appear that you cannot select one of the subprojects as a destination for the move when in
fact you can.

Steps:
1. Create new BPEL module BpelModuleA
2. Create new BPEL module BpelModuleB
3. Right Click  BpelModuleA and choose properties->project references and add BpelModuleB
4. In BpelModuleA create a new schema (name it A)
5. Repeat step 4 and name it A'
6. Right Click schema A and choose refactor->move chose BpelModuleB as the project
   (notice that the project selection drop down appears available and you can select BpelModuleB and there are no problems)
7. Right Click A' and choose refactor->move
   (now the project and location drop downs are greyed out making it seem like they are not an option but you can in
fact choose from the list.)

As far as I can tell now, after the first move refactor the project and location options become greyd out even for a new
project and moving within a project.

Not a Beta1 stopper but a FAQ candidate I would think.
