Use a hidden field on the form. Associate a custom validator with the hidden field. When the application is submitted, the custom validator compares both text field and combo box and throws a validation error only if both are null.

Because, the need to get another component's could arise in the following scenario too... ( I had this scenario ). On a form I have few input fields. One of them is school name. The school name can be input by choosing from a drop down or by entering in a text field, this piece of information is required, but I cannot set the required attribute to true because the user could choose or enter in the text field. So in my validator of the drop down I get the submitted value of the text field and if both are null throw a validator exception. I don't know if there is a better way of handling this. -Srikanth -----Original Message----- From: Matthias Wessendorf [mailto:[EMAIL PROTECTED] Sent: Friday, April 22, 2005 10:50 AM To: MyFaces Discussion Subject: Re: Cross component validation question I have created an equal validator for MyFaces (<x:validateEqual/>) <h:inputText id="passwd1" .../> <h:inputText id="passwd2" ...> <x:validateEqual for="passwd1"/> </h:inputText> but it is limited to JSF spec 1.1 ... in other words, you can't place it before passwd1 SRC can be found in CVS HTH, Matthias On 4/22/05, Srikanth Madarapu <[EMAIL PROTECTED]> wrote: > If you know the id of component B, you could get using...
