Alternate EL property reference #{entity[fieldName]} doesn't work ----------------------------------------------------------------- Key: JBSEAM-1214 URL: http://jira.jboss.com/jira/browse/JBSEAM-1214 Project: JBoss Seam Issue Type: Bug Components: Core Affects Versions: 1.2.1.GA Reporter: Joshua Davis Assigned To: Pete Muir Priority: Minor Fix For: 1.3.0.BETA1 Validation fails for inputText fields where the value expression is of the form: #{entity[fieldName]} The problem is in Expressions.java, in the validate() method: {code} public InvalidValue[] validate(String propertyExpression, Object value) { int dot = propertyExpression.lastIndexOf('.'); int bracket = propertyExpression.lastIndexOf('['); if (dot<=0 && bracket<=0) { return new InvalidValue[0]; } String componentName; String propertyName; if (dot>bracket) { componentName = propertyExpression.substring(2, dot); propertyName = propertyExpression.substring( dot+1, propertyExpression.length()-1 ); } else { componentName = propertyExpression.substring(2, bracket); propertyName = propertyExpression.substring( bracket+1, propertyExpression.length()-2 ); } String modelExpression = propertyExpression.substring(0, dot) + '}'; Object modelInstance = createValueBinding(modelExpression).getValue(); //TODO: cache the ValueBinding object! return getValidator(modelInstance, componentName).getPotentialInvalidValues(propertyName, value); } {code} This line is the problem: String modelExpression = propertyExpression.substring(0, dot) + '}'; if a dot is not found, 'dot' is -1... boom!
