Vaadin 7.4.1
Hello. For example if create CustomLayout with 120 text fields and 12 tables (empty), FireFox starts lagging. If you will click on sort header in the table you will get delay around in 1s (FireFox freezes). If you will change CustomLayout on VerticalLayout, delay will disappear. Chrome and IE haven’t this problem.
For what i need alot of components.
I developing electronic documents, sure any document has bunch of textfields and etc… Each new document opens in a new tab. With Vaadin default TabSheet all works fine, because vaadin tabsheet detaching (or removing) tab content from DOM.
But i need default implementation of Tabs, where content just hidden by css. So i had made simple tab and had tighted it with Vaadin. All was fine before i had checked it in FireFox. Then i had done a simple Vaadin application with custom layout and bunch of components, and FireFox starts freezing.
