Hi Simeon, remember the JSF-Lifecycle, and that model-beans are only updated after the conversion and validation phase has completely run?
The value-change-listeners are called ahead of the model-update-phase, and this is why you don't see the changed value in the backing beans. regards, Martin On 9/11/06, Leyzerzon, Simeon <[EMAIL PROTECTED]> wrote:
Sorry, I meant to say that calling this.getReportName() in the buidControl() listener returns null whereas event.getNewValue() works.

Could someone please explan this behavior. What is the purpose of chooser.setValue() if getting the value doesn't work? Would it be correct to do: reportName = event.getNewValue(); or is there a better way? TIA.
