hi cedric, you are right - however, we need a property name to identify the target. i'll change that - as soon as there is no property name, we don't continue with the validation process and log a warning.
as alternative you could refactor the expression so that the map-trick is not at the >end< of the expression. the issue happens quite early - so everything which is in place for skipping the validation process won't help. (you could also customize extval to change the default behavior) regards, gerhard http://www.irian.at Your JSF powerhouse - JSF Consulting, Development and Courses in English and German Professional Support for Apache MyFaces 2010/8/17 Cédric Durmont <[email protected]> > Hello, > > I'm new to ExtVal, so it's possible I'm missing something, but I have > troubles with a page containing this : > > [...] > <tr:selectOneChoice value="#{someBean.status[member]}"> > [...] > > Where status is declared as a Map (actually what I do here is the > el-map trick to call a method with an argument), and member is a POJO. > Works fine without ExtVal, but when I add ExtVal, I get an exception > when validating the page : > > java.lang.IllegalStateException: error at binding: > #{beanBenef.beneficiaire.famille.statut[membre]} -- an el-resolver > error occurred! maybe you used an invalid binding. otherwise: please > report the issue, deactivate the el-resovler of extval via web.xml > context-param: > org.apache.myfaces.extensions.validator.DEACTIVATE_EL_RESOLVER > and test again. > at > org.apache.myfaces.extensions.validator.core.el.DefaultELHelper.getPropertyDetailsOfValueBinding(DefaultELHelper.java:182) > at > org.apache.myfaces.extensions.validator.crossval.recorder.CrossValidationUserInputRecorder.recordUserInput(CrossValidationUserInputRecorder.java:56) > at > org.apache.myfaces.extensions.validator.core.interceptor.AbstractValidationInterceptor.beforeGetConvertedValue(AbstractValidationInterceptor.java:114) > at > org.apache.myfaces.extensions.validator.core.renderkit.ExtValRendererWrapper.getConvertedValue(ExtValRendererWrapper.java:468) > at > org.apache.myfaces.trinidad.component.UIXEditableValue.getConvertedValue(UIXEditableValue.java:422) > [...] > Caused by: java.lang.ClassCastException: > sap.metier.utilisateur.Beneficiaire cannot be cast to java.lang.String > at > org.apache.myfaces.extensions.validator.core.el.ExtValELResolver.setValue(ExtValELResolver.java:181) > at com.sun.el.parser.AstValue.setValue(AstValue.java:167) > at > com.sun.el.ValueExpressionImpl.setValue(ValueExpressionImpl.java:269) > at > com.sun.facelets.el.TagValueExpression.setValue(TagValueExpression.java:93) > at > org.apache.myfaces.extensions.validator.core.el.DefaultELHelper.getPropertyDetailsOfValueBinding(DefaultELHelper.java:178) > ... 80 more > > The exception is thrown here (ExtValELResolver.java:181) : > public void setValue(ELContext elContext, Object o, Object o1, Object > o2) > { > expression += "." + o1; > property = (String)o1; // <== HERE > [..] > "o" is my Map, o1 is the POJO, which is definitely not castable to a String > ! > > > The message says I can disable the resolver, which removes the error. > But then I have other messages from ELHelpher trying to resolve > complex EL such as #{bean.someMap[ value != null ? value : > 'default']}.
