Martin Grigorov resolved WICKET-5692. ------------------------------------- Resolution: Incomplete Please provide a patch and we will reopen the ticket. I cannot see the whole picture from your description. Additionally org.apache.wicket.model.AbstractPropertyModel#propertyExpression() has 'protected' visibility. I believe this issue is not a good enough reason to make it 'public'. > Misleading message in PropertyValidator > --------------------------------------- > > Key: WICKET-5692 > URL: https://issues.apache.org/jira/browse/WICKET-5692 > Project: Wicket > Issue Type: Improvement > Reporter: Thibault Kruse > Priority: Minor > > in org.apache.wicket.bean.validation.PropertyValidator.java: > {code} > if (property_ == null) > { > throw new IllegalStateException( > "Could not resolve Property from > component: " + > component + > ". Either specify the Property > in the constructor or use a model that works in combination with a " + > > IPropertyResolver.class.getSimpleName() + > " to resolve the Property > automatically"); > } > {code} > The error message is misleading, as other causes might lead to a result of > null. As PropertyResolvers can be of any type, the message should not assume > any given cause, but may hint at common errors. > In particular in my case when Using a bean Foo having a field bar of Type > Bar, and a Model on an instance foo of Foo having null for field bar. > Instead, it would be nice if the Error Message made an attempt to cast the > component model to AbstractPropertyModel and print the propertyExpression, as > well as the type of the modelObject, but without failure if the cast is not > possible, and reporting the modelObject is null if so. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
