No - if I had to guess now, after finally looking through the code carefully, I would have said it was that the bean was in request scope.
On postback, the updateMode property gets lost when the bean is instantiated anew, and therefore, the buttons rendered attribute is set to false... If the rendered attribute is false, though, the decode methode is not called for this button, and so no method is called. regards, Martin On 8/12/05, Martin Marinschek <[EMAIL PROTECTED]> wrote: > Request scope, there it is... > > set it to session, and try again - oh, you said you did, right? > > regards, > > Martin > > On 8/12/05, Gregg D Bolinger <[EMAIL PROTECTED]> wrote: > > <!DOCTYPE faces-config > > PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN" > > "http://java.sun.com/dtd/web-facesconfig_1_1.dtd";> > > > > <faces-config> > > > > <managed-bean> > > <description>Administer Categories</description> > > <managed-bean-name>categoryAdmin</managed-bean-name> > > <managed-bean-class>com.gthought.pnp.web.beans.CategoryAdmin</managed-bean-class> > > <managed-bean-scope>request</managed-bean-scope> > > </managed-bean> > > > > </faces-config> > > > > > > On 8/12/05, Martin Marinschek <[EMAIL PROTECTED]> wrote: > > > I just tried exactly your example, copied out - it works just fine... > > > > > > can you post your faces-config.xml? > > > > > > that can be the only difference now... > > > > > > regards, > > > > > > Martin > > > > > > On 8/12/05, Gregg D Bolinger <[EMAIL PROTECTED]> wrote: > > > > I take it that when you all run a similar example, it works for you? > > > > > > > > Gregg > > > > > > > > On 8/12/05, Gregg D Bolinger <[EMAIL PROTECTED]> wrote: > > > > > Ok, here is a reply to all: > > > > > > > > > > What happens if you use an h:commandButton instead? - Doesn't matter > > > > > What happens if you dump the render statement? - Then the update > > > > > method is called just fine > > > > > > > > > > Is "#{not categoryAdmin.updateMode}" legal?
