ValueChangeListener on custom component leads to PropertyNotFoundException

Question

We have a custom JSF component that renders some buttons and a select box in a specific way. This is done by a class that extends `UIInput`. This custom component used in the `xhtml` templates like so: ``` <xx:fooComponent value="#{fooBean.someProperty}" valueChangeListener="#{fooBean.someMethodInBean}" someOtherProperties="true" /> ``` Now since we changed from JBoss 4.2.2 running JSF 2.0 to JBoss 7.1.1 running with the built-in JSF libs, it complains about `someMethodInBean` not being a property. Of course it's not a property, it's a method. Who in the world would bind a property to a `valueChangeListener`? At first I thought, this had something to do with the method being in a superclass of the referenced bean, but that wasn't the case. Adding this particular method to `FooBean` did not make any difference. So my question is, what did they change so that this breaks now and how can I fix it in a migrating-friendly way? edit The component is declared as such in our `*.taglib.xml`: `…

Accepted Answer

This indicates that the tag attribute isn't been declared as a `` in the component's `` declaration in the `.taglib.xml` file as follows: ``` valueChangeListener

void valueChange(javax.faces.event.ValueChangeEvent)

``` Make sure that this is properly been declared as above. Update: you need to make sure that you've declared the `.taglib.xml` file conform JSF 2.x Facelets XSD (and thus not a DTD as it was in legacy Facelets 1.x). ``` ```
