Radim Hopp commented on JBDS-3152:
----------------------------------

Hi [~sgilda]! How did you import those projects? If as general maven projects, then I don't think cheatsheet should be opened automatically. 
Try to import them from JBoss Central. After successfull import from JBoss Central you should be prompted whether you want the cheatsheet to be opened or not.
