How to test the number of elements in compositeelement?

[martin]

Looking through the docs, I can't find a way to find the length of a composite element.

var ds = Ext.select("some-class");

alert(ds.length);

This returns "undefined", even though there are items found.

Same as your other thread. A composite is not an array. You can test the elements property length though.

var len = ds.elements.length;
