[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-1148) Validators.validate() fails with NPE when expressionString is null

Validators.validate() fails with NPE when expressionString is null ------------------------------------------------------------------ Key: JBSEAM-1148 URL: http://jira.jboss.com/jira/browse/JBSEAM-1148 Project: JBoss Seam Issue Type: Bug Components: Core Affects Versions: 1.1.6.GA Environment: Any Reporter: Mike Quilleash Assigned To: Pete Muir Priority: Optional Fix For: 1.3.0.ALPHA public InvalidValue[] validate(FacesContext context, String propertyExpression, Object value) The propertyExpression, which is extracted from a ValueBinding, by ModelValidator, may be null in some circumstances. I use custom ValueExpression implementations in a couple of places which are not derived from an EL string so return null from getExpressionString(). validate() should probably check for null and quietly 'return new InvalidValue[ 0 ]' like it does when it cannot parse the expression string properly.
