jQuery ui dialog and jScrollPane

jQuery ui dialog and jScrollPane


I have a problem when using jquery ui dialog and jScroollPane plug in.
If i call the jScrollPane function on the same div on which i open the
dialog, the dialog has initial size 0.
For example:
$(function() {
        $("#main").dialog({
            bgiframe: true,
            height: 140,
            modal: true
        });
    });
$("#main").jScrollPane();
Any solution?
