Eclipse 3.7 with instaled JBoss Tools - when I try to open faces-config.xml - mouse double click on file in Package Explorer - too long waiting for open the file - then I restart eclipse and try open it once again - in fresh copy I've drink a cup of tea - then I see the file opened. C:\RHDS\jbosstools\trunk\jsf\tests\org.jboss.tools.jsf.text.ext.test\projects\HiperlinksTestProject\WebContent\WEB-INF\faces-config.xml
