uibinder - GWT, CssStyle being injected multiple times -


i have been using clientbundle , cssresources quite time have noticed styles getting injected many times. 1 thing can point finger use quite few <ui:with field='resources' type='com.vf.client.resources.resources' /> in templates , suspicion creating multiple copies of clientbundle. 1 thing may cause use ray ryan's concept of caching views in clientfactory of views created before ever being attached dom. in base view use provided=true on resources not let uibinder generate new 1 me. may not working though, suspecting , ui:with creating new copy , ignoring provided=true. have used developer tools in chrome , firebug see , in both cases style getting injected many times. not sure on how resolve problem without removing resources class uibinder templates , make quite bit of work. ideas appreciated.

/**  *   * @author chris  */ public abstract class viewimpl extends composite implements iview, requiresresize {      @uifield(provided = true)     public final resources resources;  }     public interface resources extends clientbundle, celltable.resources, celllist.resources, datagrid.resources {      /**      * these obfuscated styles.      *       * @return      */     @source({ "default.css", "default-external.css"})     public style style(); }

update

i have been using factory/singleton make sure creates one. create resources clientbundle in clientfactory implementation when application starts. in application start call ensureenjected on style , on ensureinjected never called in code.

this factory gets singleon request factory. used have static initializer inside interface moved while clean multiple styles problem.

import com.google.gwt.core.client.gwt;  public class resourcesfactory {      private static resources instance = null;      private resourcesfactory() {     }      public static final resources getresources() {         if (instance == null) {             instance = gwt.create(resources.class);         }          return instance;     } }

my client bundle gets initialized , injected here only.

  @override     public void onmoduleload() {         if (window.location.getparametermap().containskey("debug")) {             window.alert("remote debugging enabled, see server log debug information");             remotedebugservice.enable();             }          try {             clientfactory = clientfactory.instance;             masterlayoutpanel = clientfactory.getmasterlayoutpanel();         } catch (exception e) {             logger.log(level.severe, "unable instantiate clientfactory", e);             window.alert("somebody broke build, add ?debug url enable remote debugging" + e.getmessage());         }          rootlayoutpanel.get().add(masterlayoutpanel);         styleinjector.inject(clientfactory.getresources().style().gettext());          placehistoryhandler historyhandler = new placehistoryhandler(clientfactory.getplacehistorymapper());         placecontroller placecontroller = clientfactory.getplacecontroller();          // start placehistoryhandler our placehistorymapper         historyhandler.register(placecontroller, clientfactory.geteventbus(), defaultplace);          startapplication(clientfactory, historyhandler);         }

what mean injected multiple times?

clientbundle's singleton's (see thread will referring single clientbundle class multiple uibinders cost anything?).
shouldn't matter if use provided=true or not.

but if want avoid clientbundle proxy can use gin or factory instantiate (gwt.create or magically via @inject ) clientbundle once , inject views guess in compiled code won't make of difference.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
