Re: GWT 2.9 compatiblity with GXT 2.3.1a

Yes, I agree changing the line in the GXT 2.3.1a file from:

To this:

Would seemingly fix the issue. However I would then need to compile this to a .class file to replace the one in the gxt-2.3.1a-gwt22,jar that I reference in my project and therein lies the problem.  Must I track down all the dependencies for GXT and GWT so that I can do a full recompile from source just for this one line change? Or can I use a java byte code editor to simply insert the .toString() at the right place in the .class file for ListField? I'm not sure how to do that, so I'll have to read up on byte code editors as that seems easier than a full recompile - if I knew where and how to inject the .toString()

However if the OP already had GXT 2.3.1a working with GWT 2.8.2 then I'm guessing they already had to do this operation, and may be able to provide some insight. Unless they were using Java 7 and this is only a Java 8 issue perhaps.

The updated JDT probably caused this (so that gwt 2.8.2 can support Java 8 language features) - at a guess you'll need to cast the result of m.get(prop) on that line to Object so that StringBuilder.append correctly uses the Object overload.

Hi, I am attempting to update to GWT 2.8.2 from 2.7.0 using GXT 2.3.1a however I get the following error:

How were you able to get 2.8.2 working with 2.3.1a?  I'm running Java 8 with compiler compliance set to 1.7

Hi All,

Currently our application has below versions -
1. GWT - 2.8.2
2. GXT - 2.3.1a

We are planning to upgrade GWT from 2.8.2 to 2.9.0. But have query regarding its compatibility towards GXT 2.3.1a.
I have gone through GXT Compatiblity version matrix page, but found nowhere officially mentioned that its supported.
So can you please confirm that GWT 2.9 is officially supported with GXT 2.3.1a?
