Re: Urgent!!!!!!!!!!!!!!!!!!!!!!!!!!! GWT 2 Memory leak
Hi, IE are known to have memory leaks. There is not much GWT can do . You can avoid to create and delete DOM-elements. Try to reuse them. Thats the best you can do with IE. Or convince your customer to use a modern browser like Safari/Chrome/ Firefox.

Thank you in advance. I am using a data table that has been developed in JQuery. And it seems that when I go to another page My application still references the same datatable.

Re: Urgent!!!!!!!!!!!!!!!!!!!!!!!!!!! GWT 2 Memory leak
If it is an obvious problem in your code, you should be seeing memory leaks in all browsers(which I believe you said you have). If that is the case, you should be able to use the Speed Tracer plugin for chrome. It tells you how many instances of which objects are being created so that you can try and debug where you are holding a reference to the object. Remember, in javascript there is no concept of weak or soft references, so you have to be holding on to an object somewhere in the DOM in order for there to be a memory leak. A memory leak is not something that people here will be able to help you solve directly, we can only give you pointers on ways to narrow down the search. Also, if you are using flash, it is a common source of memory leaks and it would explain the leaks persisting beyond the single page(this could also be explained by a Java applet because only one JVM is used throughout the entire browser).
