The problem is that you're mixing the nice new data binding stuff with the
antique Table widget. The Table widget is wonderful, and there's not yet a data
binding-version of it, so you need to do a bit of fiddling to get the two to
work together.
Data binding uses a class called qx.data.Array for its results. The reason is
that it's all based on property value changes, so each element of a model must
be a property. What you get back from your Rest method, then, is apparently a
qx.data.Array value, not a native array.
The Table widget predates (by many, many years), the advent of qx.data.Array
and data binding. It accepts, as its model (for qx.ui.table.model.Simple), a
native array.
The method toArray() of the qx.data.Array class converts the model stored in
the qx.data.Array instance into a native array.
So in fact, you just need to do what it's saying, which is to call the
toArray() method on that qx.data.Array object you're getting in the event data,
and pass that to tableModel.setData().
Don't worry. There are plans for a data binding implementation of a Table. It
just hasn't been done yet.
Here's my current code:
var __tableModel = new qx.ui.table.model.Simple();
__tableModel.setColumns([ "Date", "DelayAvg", "First", "Last" ]);
var url = "/avg_checkin_times/" + label;
var jsonFetcher = new qx.data.store.Json(null);
jsonFetcher.addListener("loaded", function(e) {
__tableModel.setData(e.getData().toArray());
}, this);
jsonFetcher.setUrl(url);
var table = new qx.ui.table.Table(__tableModel).set({
decorator: null
});
I'm still getting a table with the right number of rows but the first column
says "please use toArray() to see the content.
So I tried this:
var url = "/avg_checkin_times/" + label;
var jsonFetcher = new qx.data.store.Json(null);
jsonFetcher.addListener("loaded", function(e) {
tData = e.getData().toArray();
tData1 = []
for (item in tData) {
tData1.push(item.toArray());
}
__tableModel.setData(tData1);
}, this);
jsonFetcher.setUrl(url);
Error says "item.toArray() is not a function".
I also tried it with tData = e.getData();
Same error.
I don't know what I'm doing wrong here.
It would be very cool if you could tell the JSON fetcher to not even bother
converting the results into Objects but keep them as native. It would save a
lot of processing on a big load if that could be toggled "up front", and it
would solve problems like these (and using the JSON results with other
Javascript tools).
Big thanks for the help! I really need to get this working.
