[jboss-user] [JBoss Seam] - Alternate property reference style in EL not working

It looks like http://jira.jboss.org/jira/browse/JBSEAM-580 has resurfaced. I'm using Seam 1.2.1.GA and I get a String index out of bounds exception when I use the alternate syntax for referencing an entity property: #{entity[fieldName]} Here is the stack trace: 18:57:39,147 ERROR [STDERR] java.lang.StringIndexOutOfBoundsException: String index out of range: -1 | 18:57:39,148 ERROR [STDERR] at org.jboss.seam.ui.ModelValidator.validate(ModelValidator.java:32) | 18:57:39,148 ERROR [STDERR] at javax.faces.component._ComponentUtils.callValidators(_ComponentUtils.java:157) | 18:57:39,148 ERROR [STDERR] at javax.faces.component.UIInput.validateValue(UIInput.java:312) | 18:57:39,148 ERROR [STDERR] at javax.faces.component.UIInput.validate(UIInput.java:353) | ... | Basically, the following method in Expressions.java throws because 'dot' is -1: | 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); | } | Does anyone know of a way to work around this? I'm trying to make a generic Facelets tag for input fields and I can't because it won't let me bind to a property using this syntax.
