I see the jar file name for GXT 2.3.0 = gxt-2.3.0-gwt22.jar. Does this mean it's expecting GWT 2.2?? Seems kinda odd considering GXT 2.3.0 was released Oct. 2013 and GWT 2.2.0 was released Feb. 2011 (3+ years prior). I tried GWT 2.6.1 and get an error in the GXT jar (HtmlEditor.java Line 548: Type mismatch: cannot convert from com.google.gwt.dom.client.Element to com.google.gwt.user.client.Element) so I'll try GWT 2.5, then 2.4, etc...
PS I know this is WAY old stuff. I just need a temporary "fix" to run on IE10 then I'm going to go strictly with GWT; no more GXT. Thanx, ~rfh
GXT2.x works with GWT upto 2.5.1 version. While according to official documents GXT 3.X works with GWT 2.6.1, I myself tried GXT 3.X with GWT 2.7.0 and no problems till now.
