Hi everybody,
I am using jboss-4.0.5 and jboss-seam-1.1.0.CR1.
I have tried to use ajax4jsf in an application generated by reverse-engeneering.
I have followed the instructions I read in paragraph "14.2. Configure Ajax4jsf"
of "JBoss Seam: Simplicity and Power Beyond Java EE 5.0":
1. I put the following xml in web.xml
<filter>
| <display-name>Ajax4jsf Filter</display-name>
| <filter-name>ajax4jsf</filter-name>
| <filter-class>
| org.ajax4jsf.Filter
| </filter-class>
| </filter>
| <filter-mapping>
| <filter-name>ajax4jsf</filter-name>
| <servlet-name>Faces Servlet</servlet-name>
| <dispatcher>REQUEST</dispatcher>
| <dispatcher>FORWARD</dispatcher>
| <dispatcher>INCLUDE</dispatcher>
| </filter-mapping>
| <context-param>
| <param-name>
| org.ajax4jsf.VIEW_HANDLERS
| </param-name>
| <param-value>
| com.sun.facelets.FaceletViewHandler
| </param-value>
| </context-param>
|
2. In faces-config.xml I commented
<view-handler>
| com.sun.facelets.FaceletViewHandler
| </view-handler>
|
3. I put META-INF ajax4jsf.jar, oscache-2.3.2.jar, el-api.jar, el-ri.jar,
jsf-facelets.jar in <my-app>.jar of my <my-app>.ear
Finally I have replaced
<h:commandButton id="update" value="Save"
| action="#{usersHome.update}"
| rendered="#{usersHome.managed}"/>
|
with
<a4j:commandButton type="submit" value="Save"
| reRender="description"
| action="#{usersHome.update}"
| rendered="#{usersHome.managed}" />
in my .xhtml page.
I get the following error:
javax.el.PropertyNotFoundException: Bean:
it.severn.data.UsersHome$$EnhancerByCGLIB$$54529d2b, property: update
at
com.sun.facelets.el.LegacyELContext$LegacyELResolver.getValue(LegacyELContext.java:146)
at com.sun.el.parser.AstValue.getValue(AstValue.java:117)
at com.sun.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:192)
at com.sun.facelets.el.ELText$ELTextVariable.toString(ELText.java:174)
Notice that I checked my deployment many times and it conforms to the previous
instructions and that #{usersHome.update} is not a property, but an action.
A previous post (describing a very similar problem, but non explaining the
solution) says that anonymous wrote : Facelets when not finding a tag library
instead of putting up an ugly error message ingnores it and instead tries to
evaluate the EL as a property access.
Does that means that Facelets do not find a4j tags? With seam tags everything
is ok, of course.
Could anyone help me to find out where I am wrong ?
Thanks in advance Francesco
