问题 I create a window containing grids that send off ajax requests. Now, I immediatley close the window again before the grids are fully created and the ajax requests return.

问题 I am working with Extjs4. I am trying to send accented characters to server. I was trying to send ó. And what I was receiving at the server side was ó. I am sending it using Store proxy. In store proxy, I have added headers: { 'Content-Type': 'charset=utf-8' } Still it did not send the accented characters properly. How should I send accented characters to the server?

问题 I have a grid with row-editing enabled. When I add a row and call store.sync(), the server generates certain fields on that record, and returns the full record info in the response. However, ExtJS does not seem to update its copy of the record, except for the id. Is there a way to make it do that, or do I need to write custom code?
