Hi Max, Thanks for your response. According to the TLD, SelectManyListBox doesn't have partialSubmit http://myfaces.apache.org/trinidad/trinidad-api/tagdoc/tr_selectManyListbox.html and I get this exception when trying to use it org.apache.jasper.JasperException: Attribute partialSubmit invalid for tag selectManyListbox according to TLD
I am using autoSubmit, as suggested in this tutorial: http://wiki.apache.org/myfaces/Partial-page_rendering but as I said earlier, it is re-rendering the whole page. Other ideas? jessica On Nov 7, 2007 3:04 PM, Max Starets <[EMAIL PROTECTED]> wrote: > Jessica, > > have you tried setting partialSubmit="true" on the listbox A? > > Regards, > Max Starets > > Jessica Johnson wrote: > > Hi all, > > > > I just started using Trinidad 1.0.1 and would like to use PPR so that > > when a value is selected in a SelectManyListBox A, it re-renders > > SelectManyListBox B with some of the options disabled.
