[jboss-user] [JBoss Seam] - Seam validation problem with facelets source tag

Here is what I am trying to do: 1. Create facelets source tag: In taglib: | <tag> | <tag-name>address</tag-name> | <source>xhtml/address.xhtml</source> | </tag> | In address.xhtml: | <ui:composition ...> | ... | <s:decorate> | <h:inputText | value="#{address.street}" | id="street" | </h:inputText> | </s:decorate> | ... | </ui:composition> | 2. Now in my facelets that uses the tag: | | ... | <s:validateAll> | ... | <v:address address="mybean.billingAddress"/> | ... | </s:valiateAll> | ... | | The facelets loads fine with the address source tag, and when I enter invalid data in fields from address.xhtml, submit the form and I get the proper validation error messages, so far so good. But if I enter the valid data and submit form, I got the following stack trace: | Caused by: java.lang.NullPointerException | at org.jboss.seam.core.Expressions.getValidator(Expressions.java:198) | at org.jboss.seam.core.Expressions.validate(Expressions.java:182) | at org.jboss.seam.ui.ModelValidator.validate(ModelValidator.java:25) | at javax.faces.component._ComponentUtils.callValidators(_ComponentUtils.java:157) | at javax.faces.component.UIInput.validateValue(UIInput.java:312) | at javax.faces.component.UIInput.validate(UIInput.java:353) | at javax.faces.component.UIInput.processValidators(UIInput.java:183) | at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:624) | at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:624) | at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:624) | at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:624) | at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:624) | at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:624) | at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:624) | at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:624) | at javax.faces.component.UIForm.processValidators(UIForm.java:70) | at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:624) | at javax.faces.component.UIViewRoot.processValidators(UIViewRoot.java:146) | | If I change the address.xhtml to use #{mybean.billingAddress} directly like this: | <ui:composition ...> | ... | <s:decorate> | <h:inputText | value="#{mybean.billingAddress.street}" | id="street" | </h:inputText> | </s:decorate> | ... | </ui:composition> | Then the problem goes away, although this works, but it defeats the purpose of reusing the tag in several other places. Any idea? Thanks. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4043449#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
