Typical UIInput behavior: Decode phase -> Is there a value in the POST values with the current component's client ID? If so, set the submitted value to that
Validate phase -> If there is a submitted value, get the converter If there is a converter, convert the submitted value using getAsObject Validate the submitted value If valid, set the local value Update phase -> If there is a local value, update the value binding property Render phase -> If there is a submitted value, render that Otherwise, get the value from the component If there is a converter, convert the value using getAsString Render the value So as you can see, as long as a UIInput control has a submitted value, it will never render the value from the value attribute of the component. Typically submitted values are only cleared in the validate method of UIInput (if the converted value is valid) On 7/6/07, Toppac <[EMAIL PROTECTED]> wrote:
