[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-6346) New Struts/JSF Project Wizards slowdowns while typing the name for the project

[Rob Stryker (JIRA)]

    [ https://jira.jboss.org/browse/JBIDE-6346?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12535717#action_12535717 ] 

Rob Stryker commented on JBIDE-6346:
------------------------------------

Looking at the code so far (RegistrationHelper), I've noticed the following.  One call to 	public static boolean isRegistered(String appname, IServer server)  gets the list of Child modules (which takes time), and then at the bottom of the method, calls public static boolean isRegistered(IProject project, IServer server) , which *again* gets the list of child modules (taking more time again). 

So one call to isRegistered(String, IServer) makes two calls to a long-running method to get the list of children. However, because this class is full of static methods, every key-press in the wizard calls isRegistered(String, IServer) which calls the validation twice. 

I'll get a patch to enable a constructor if people want to use it which can cache the list of child modules and not be forced to call it again. This should make the first key-press in name take a short while (same as now) but each subsequent keypress should go much faster.
