问题 In a GWT based application (Google Gerrit in particular), I'm getting an exception (while executing the gerrit review command): com.google.gwtorm.server.OrmConcurrencyException: Concurrent modification detected at com.google.gwtorm.jdbc.JdbcAccess.execute(JdbcAccess.java:449) at com.google.gwtorm.jdbc.JdbcAccess.updateAsBatch(JdbcAccess.java:270) at com.google.gwtorm.jdbc.JdbcAccess.update(JdbcAccess.java:223) Is there a way to identify which data in particular caused the concurrency error?

问题 Hi I'm trying to retrieve a linkedhashset from the Google datastore but nothing seems to happen. I want to display the results in a Grid using GWT on a page. I have put system.out.println() in all the classes to see where I go wrong but it only shows one and I don't recieve any errors. I use 6 classes 2 in the server package(ContactDAOJdo/ContactServiceImpl) and 4 in the client package(ContactService/ContactServiceAsync/ContactListDelegate/ContactListGui). I hope someone can explain why this

问题 I am trying to split my project into 4 Java modules: web-client web-client-admin web-client-landing web-client-core The module web-client is the one that puts all pieces together, so the dependency tree would look something like this: <-- web-client-admin <---- / \ web-client <--- <---- web-client-core \ / <-- web-client-landing <-- In my module.gwt.xml I am having: <inherits name="com.mz.client.application.landing" /> <inherits name="com.mz.client.application.admin" /> <inherits name="com.mz

问题 I remember stumbling upon a benchmark comparing jQuery vs GQuery (run time selectors) vs GQuery (compile time selectors). Once the site was loaded one could click "Start" and the benchmark (mostly CSS selectors) would run for all three versions and present the results (overall time spent) after finishing. Unfortunately, I cannot find it anymore. I do not refer to the "horse race" benchmark in Ray Cromwell's excellent video. Does anyone know this benchmark and provide me with the link? Thanks!

问题 is it possible in GWT to clone a panel? If so, are all the handler settings copied as well? Basically I have a Panel full of controls, all laid out, I want to copy it and pop it up in a PopupPanel without having to go through the code that created the controls in the first place. I got as far as DOM.clone(), and this message post. But there is no wrap() in Widget, UIObject etc. setElement() is protected. 回答1: Have you considered creating a new GWT widget, consisting of all of those controls?
