Well, the 'id' attribute that you set when doing new Y.TextField({ id: 'someid' }) is the id defined in the Widget class. It will be set by the Widget class as the id of the boundingBox.

The gallery Form utility is always adding the "-field" suffix to the id of the input node. That's a convention defined by the Form utility. You can change the suffix by changing the Y.FormField.FIELD_ID_SUFFIX property or you can change the id of the field node after it's been rendered by doing

However, I don't think that would be a good practice. I'd definitely file a bug/enhancement request for an attribute that allows you to set the id of the input.

Thanks Juan and Greg.

Firstly, I should say the reason for me posting this question. I was trying to obtain the values of form fields on the server code. I just set the id for a TextField component and forget to specify the name. I was trying to get the parameter using id and it was null. So I just looked at the html in firebug and found out that the id that I gave for TextField was set to the bounding box and not the actual html element while the id for the text field element was myid-field. Without realizing that I was not setting the name I posted this question. So this came out due to bug on my code. Once I set the name everything worked fine.

I agree with Greg's theory of setting id to the bounding box and not the actual html field. I definitely do not have a compelling use-case to have an option to be able to set id directly for html element.

Sorry for posting a dumb question. But nonetheless, the replies from you guys helped me understand a lot of things.
