I understand this.

The problem is that we use <f:selectItems ......
And we fill the list dynamically from the database tables.
There is occurrence with required and there is occurrence with not required.
We would like to control this with attribute like a required..

For example : I have this component on a search form:

<rich:comboBox required="false" value="#{searchController.sessionData.unionSearchCrit}">
<f:selectItem itemValue="Oregon" />
<f:selectItem itemValue="Pennsylvania" />
<f:selectItem itemValue="Rhode Island" />
<f:selectItem itemValue="South Carolina" />
</rich:comboBox>

When the form is shown first time there is no choosen item. This is blank.
And if user chooses an item he will not able to choose the blank ("first") item till then he reload the page.

So I would like to allow for user can cancel his decision.

The comboBox defaultLabel element is disappeared from the list when a user change value.
required="false"

How can I do that the user can set the first element (which is the default label) again?
