I am using a Sharepoint 2007 customized people picker control for a webpart (PickerDialog, CustomQueryControl, EntityEditorWithPicker). The control was working fine but the Sharepoint SP3 was applied and the control no longer allows me to expand a group entity to individual entities during a postback in the text box after the item is selected from the people picker dialog box.
I have tried OnValueChangedClientScript but can't access the text box. I would like it to expand a group entity to individual entities the way it used to before the SP3 was applied. I understand that SP2 was more forgiving than SP3, but is there a code workaround?
Additional information: I assigned the new values to CommaSeparatedAccounts after the Dialog Box exits and a postback occurred, then we could update the people picker text box with new values and then set the CommaSeparatedAccounts, SP3 no longer has the postback and will not change values in the Textbox by setting the CommaSeparatedAccounts.
