Re: porting older app from 2.5.0 to 2.8.2

Were you able to resolve the error in ListField?  I have the same error trying to get GWT 2.8.2 working with GXT 2.3.1a.

Hi all,

I was wondering if some one can help me on this one...
I have a older app which uses gxt.2.2.5-gwt22.jar, and when compiling with gwt 2.8.2 Im getting some errors like this:

 [ERROR] Errors in 'jar:file:/xxxxx/gxt-2.2.5-gwt22.jar!/com/extjs/gxt/ui/client/widget/form/'
     [java]                [ERROR] Line 322: The method append(boolean) is ambiguous for the type StringBuffer

  [ERROR] Errors in 'jar:file:/xxxxxx/gxt-2.2.5-gwt22.jar!/com/extjs/gxt/ui/client/widget/form/'
     [java]                [ERROR] Line 548: Type mismatch: cannot convert from to
     [java]          [ERROR] Hint: Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly

Im guessing other gxt.jar file needs to be used, which adopts the small changes.
I searched on the net, found some but not sure if this are the one to go with. e.g a jar called gxt-2.3.1a-gwt22.jar, also this one on git:

Can some one give me some insides on this one, that would be great!!

Tnx in advance,
