@David. Yes. I did. I ve been using GXT for a couple of years now. Even wrote some extensions.
But for the type of application I m working now Ext JS is the framework customers chooses. So it was either do it in pure JS or write a wrapper. I choosed the second. Hopefully other people will find this useful. You can see a preview here by the way : http://eemi2010.github.io/ext4j The first release should come out soon. 2013/12/11 David Hoffer <[email protected]> > Okay sounds like you've thought about the GXT option/issues. > > > On Wed, Dec 11, 2013 at 12:02 PM, Alain Ekambi <[email protected]>wrote: > >> @David >> >> Good question.
