f:convertDateTime converter error

[Adrian Enns]

I have the following code in a JSP/JSF page:

<h:inputText id="expectedCompletionDate" styleClass="screenFields" size="15" value="#{EducationController.expectedCompletionDate}">
<f:convertDateTime pattern="MM/dd/yyyy" />
</h:inputText>

It gives me the following error, any ideas? (p.s. the exact same code seems to work fine in some code before this..???) I have tried making sure that my date isn't null, but that doesn't seem to be the problem.

I know you said you checked it, but it really looks like that value is null, judging from the method that's giving you trouble:

public static boolean isValueReference(String value) {
 
if (value == null) {
    throw new NullPointerException();
}
        if ((value.indexOf("#{") != -1) &&
            (value.indexOf("#{") < value.indexOf('}'))) {
            return true;
        }
        return false;
 
    }

If it's not null, does playing around with the immediate attribute help?
