ClassCastException running rich:dataTable example with db filtering.

vins76 Jul 21, 2011 5:04 AM

Hi all,

i have a problem running ArrangeableModel example described in richfaces 4 showcase.

The method createFilterCriteria of JpaDataModel class throws an exception at line :

String propertyName = (String) filterField.getFilterExpression().getValue(facesContext.getELContext())

In fact, ValueExpression tries to coerce to Boolean a String.

The filterExpression in rich:column is #{property}

Thanks in advance.

Vincenzo.

Hello,
I'm afraid this is a bug in Richfaces 4.0 Final release. In fact there's no ArrangeableModel demo in richfaces-showcase 4.0 Final: the example you can see at http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=dataTable&sample=arrangeableModel&skin=blueSky
is not included in the war file available at https://repository.jboss.org/nexus/content/groups/public/org/richfaces/examples/richfaces-showcase/4.0.0.Final/

Luckily, I've downloaded the 4.1 Final release and with these news libs my app uses ArrangeableModel filtering options without any problems.

Best regards,
Jordi
