Dialog position has different default behaviour from Version 1.10.4

[vergules]

$('#dlgTest').dialog({

modal: false, height: 200, width: 400, position: null

});

will place dialog at the top of window. Prior version would have it at default Center of window position. Passin undeifned instead of null works as prior version and puts dialog at center This change of behaviour started at version 1.11.x.

null is not a valid value in either version.

[vergules]

Version 1.10.0 accepted null or undefined - the default position in this case is center of window. Version 1.11.x defaults to center only if undefined is used, this is a change that I was not aware of.

No it didn't. The fact that it happened to work doesn't matter. Please read the docs for acceptable values.
