We mentioned memory leaks in GXT 3.1.1 and also GXT 2 Grids. They only appear with InternetExplorer 11 (11.0.9600.18163). We couldn't test lower Versions of IE, but the issue doesn't exists for other browsers like Chrome or Firefox.
The issue could simply be reproduced by creating a standard Grid with a few columns and refresh the data in the grid a couple of times. In our test we added round about 15000 entries with every refresh. The used Store is a ListStore. Before we add new Items we delete the old ones. There is no reference to the old items anymore.


store.deleteAll();
store.add(generateDummyData());

The used memory is varying but the overall trend goes up until an out of memory exception is thrown.It is not possible for us to upgrade our GXT 2 and 3 Applications to GXT 4 (If this could solve the issue). We need to apply a fix to the older versions.
