I have made, with extjs 3.4, an webapp. I have a grid that i want to group with field 'street' but i can't. My code is here: http://pastebin.com/ZqyysxZg I think i have all the code like this example: http://dev.sencha.com/deploy/ext-3.4.../grouping.html
I don't know why the grid doesn't group. I get all the data from a database with ajax and php that generate json. All fields shows up. The unique problem is the non grouping. I'm also get no errors.
Someone could help me with that?
