[jQuery] .get(0) fails in 1.2.5

[jstrebel]

Hi there,

Noob.. and first post. Thanks for helping:

When using jquery 1.2.1 this call

var task = $("#task_"+checklist_id+"_"+task_id)[0];
or
var task = $("#task_"+checklist_id+"_"+task_id).get(0);

both return: [object HTMLTableRowElement]

which is correct. (we are appending rows to a table...)

But in 1.2.5 - same calls return: undefined

which then makes my next function,
$.data(task, "name", id);  fail.. w/ message "elem has no properties"

Any ideas? Thanks.
