Dojo Dialog boxes clearing dijit filteringselect / comboboxes

Question

Hi I'm having a small issue with a form that uses dojo for validation and other UI tasks such as auto complete etc.

The form is dynamic so that elements can be added by the user by calling a sub form within a dojo dialog box. This adds other elements to the form quite nicely however, all filtering selects or comobo boxes have their values removed.

So if a user changes the value or not, as soon as the click on the button to display the dialog the values disappear.

Is there a reason for this? I'm not doing anything other than

dojo.byId('mydialog').show();

and it's wiping the values.

Is this something that I might have to submit a bug report to the dojo team?

The version I am using is 1.3 of the tool kit.
