Re: Emulating CompletableFuture with Promise
I decided to package this up in a standalone library so it can be used
until such time that it makes it into a GWT release.

Re: I need java.util.Collections synchronized classes.
You place it wherever you want in your source tree, usually at src/emul or src/super I think. So you'd have src/emul/java/util/Collections.java Then add to your gwt.xml file. Someone else can help fill in the details I've missed, I'm a little fuzzy on the specifics of how the path gets resolved or the canonical location for the super-source directory, but that's the idea.

Strange Behavior from scheduleIncremental
Browser: Firefox 25 GWT: 2.5 I'm changing the implementation of a scatterchart I have to update incrementally to avoid the slow script warning. I've successfully implemented this using Scheduler.scheduleIncremental. However, there is one oddity I'd like to better understand: The chart is only updated when the user is actively performing input e.g. moving the mouse, but it does not progress if no input is performed at all, though the browser UI is not hung. Is this behavior a setting I've missed? A (potentially fixed in 2.6 or 2.7) GWT bug? Something else? I'd really appreciate any insight others could provide into this behavior. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: The Future of GWT Report 2012 Published
There's a mention about "very good tools for automated tests, such as Jucikito" but Google doesn't find anything for Jucikito, is there a typo? I'd love to know what this "very good tool" is exactly.

AutoBean Category Implementation Inheritance
When using AutoBean Categories Given: I have two interfaces, A and B B extends A I have a Category class for each, ACategory and BCategory I have an @Category annotation on my ObjectFactory for each Question: will the AutoBean produced by factory.b() have the methods implemented in ACategory and in BCategory, or only those in BCategory? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
