I am current having a problem with the size of the TreeStore's data.
I am doing an App, that needs to show a tree in a NestedList.
This data needs be show offline, so i built a json file and put it on "resources/data" folder.
However, this has became a 2.5mb file, and the NestedList has became slowly to navigate in it.
I can't think on an other way to do it.
I have already thought in use a List in the place of NestedList, and then create different files to the children, but it seens a big workaround to me.
I'm not sure if NestedList will work; you may need to intervene programmatically a little more with this proxy, creating stores on the go with a remoteFilter set to the relevant parent ID.
I'd start with a simple list example and go from there.
I would populate the websql if it hasn't already been populated at the start of the application, yes.
