They only get in #textAreaWithValue: callback: if they are not set before.
You can set them the same way you can set any attribute of an html element.

	html attributes
		at: 'rows' put: [ 5 ];
		at: 'cols' put: [ 40 ].
	html textArea....

There is no such thing as a page, just components. I don't see what
you want to do, but you probably are looking for #call:, perhaps in
conjunction with a WATask.
