hello,
I'm using jboss-4.2.0.CR1 and jboss-seam-CVS.20070416.
This flow was working fine with jboss-4.0.5.GA and previous version of Seam
I have xhtml page containing multiple required fields. The page is part of a page flow. If I click the next button without filling out the required field, an exception is thrown when the page is re-rendered due to a class not being loaded properly.
The class is used in the custom method pc:displayType.
This methods works fine is that same page. It is only when redisplayig the page because some required field are null, that the exception occurs.
Here is the part of the xhtml:
| <f:subview id="select" rendered="#{pageAction.displayChoice}">
| <h:selectOneRadio id="userType" value="#{pageAction.userType}" required="true" layout="pageDirection" styleClass="radio" converter="#{pageAction.userTypeConverter}">
| <f:selectItems value="#{pageAction.userTypes}" />
| </h:selectOneRadio>
| </f:subview>
| <f:subview rendered="#{not pageAction.displayChoice}">
| <h:outputText value="#{messages[pc:displayType(categoryType, pageAction.userType)]}" styleClass="boldText" />
| </f:subview>
|
The exception is:
