checkbox and form problem

[crosemffet]

I have one form with one checkbox, source:
{name: "mycheck",
Id: "mycheck",
title: "mycheck",
type: "checkbox",
valueMap:[0, 1],
defaultValue: 1
},

then, I have one button with some js operations.
everything goes fine, except each time I ask for the checkbox value, I get on e js error: object required

the error fires in the following sentence:
document.getElementById("mycheck").value
what's wrong..?

Use formId.getValue("mycheck").

Don't go against the DOM directly. Firstly, SmartClient components aren't DOM elements, but JavaScript objects which generate a DOM as needed. A FormItem, for example, may exist, be tracking a value, and respond to various APIs, but not be drawn and have no DOM representation.

Second, direct DOM access is where all cross-browser bugs come from. Still to SmartClient JavaScript APIs and you don't have to worry about those.

Oh also, it's "ID" not "Id".
