Re: [ANN] Practical Apache Struts2 Web 2.0 Projects
Im having 1 little problems with Practical Apache Struts2 Web 2.0 Projects
examples
The first one is that even EntityManager do not persist when submiting the
contestants says "detached persist", I have solved it using
entityMgr.merge(event); instead of entityMgr.persist(event);
the second is a problem with tomcat, when debuging(and only runnig the
debbuger, tomcat 5.5) under eclipse, the more strange is that it doesn't
happend if I add a user but creating a envent prints
avax.servlet.ServletException: Error setting expression 'model' with value
'com.fdar.apress.s2.domain.Event@12adac5'
org.apache.struts2.dispatcher.Dispatcher.serviceAction(Dispatcher.java:515)
..........
causa raíz
Error setting expression 'model' with value
'com.fdar.apress.s2.domain.Event@12adac5' - [unknown location]
com.opensymphony.xwork2.util.OgnlValueStack.setValue(OgnlValueStack.java:171)
................
No object in the CompoundRoot has a publicly accessible property named
'model' (no setter could be found). - [unknown location]
at
com.opensymphony.xwork2.util.CompoundRootAccessor.setProperty(CompoundRootAccessor.java:68)
......................
but getModel and setModel are defined in BaseEventAction where interface
ModelDriven is used
I will try tomcat 6 to see if it is that solves, If you already know wath it
is, please, I will be here reading

Hi All,
I got the issue resolved using the
<package name="enterEvent" namespace="/event" extends="base-package">
<interceptors>
<interceptor name="flash"
class="com.opensymphony.webwork.interceptor.FlashInterceptor" />
<interceptor-stack name="eventStack">
<interceptor-ref name="scope">
Model
partialEvent
true
</interceptor-ref>
<interceptor-ref name="flash"/>
<interceptor-ref name="paramsPrepareParamsStack"/>
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="eventStack" />
<action name="addEventFlow"
class="com.fdar.apress.s2.actions.event.BaseEventAction">
<interceptor-ref name="eventStack">
start
</interceptor-ref>
<result>/WEB-INF/jsp/event/enterEventDetails-input.jsp</result>
</action>
<action name="completeEvent"
class="com.fdar.apress.s2.actions.event.BaseEventAction">
<interceptor-ref name="eventStack">
end
</interceptor-ref>
<result>/WEB-INF/jsp/event/eventReview.jsp</result>
</action>
<action name="flashedSelectEventType"
class="com.fdar.apress.s2.actions.event.SelectLocationTypeAction">
<interceptor-ref name="flash">

</interceptor-ref>
<interceptor-ref name="eventStack" />
<result>/WEB-INF/jsp/event/selectLocationType-input.jsp</result>
</action>
</package>
It the same configuration only thing is there are minor changes here and
there.

Are you using the OpenSessionInViewFilter? If you aren't, you'll want to.
If you are doing that already, you may be trying to persist when you should
merge. If you're using Hibernate's API directly, take advantage of
Hibernate's saveOrUpdate() method, rather than the JPA merge()/persiste()
methods.

I have solved the persistence problem.
Change EntityManager.persist(event) to
EntityManager.merge(event)

I'm not sure, and I'm only taking an educated guess at it being
OS/platform-dependent (since a JAR that worked for me had problems for
another user). Unfortunately I can't reproduce the error. I'm all for
doing the work to fix the problem if someone has the problem and cycles
to work through testing it.

Hmm, why does that fix it? If it's an OS-dependent issue we should fix it for

There have been cases (unfortunately not with myself or the tech
reviewer, otherwise it would have been corrected) when the same error
message (No object in the CompoundRoot has a publicly accessible
property named 'model' (no setter could be found). - [unknown location])
has been displayed. I believe it may be based on OS.
The solution provided to me was to change the scope interceptor
reference to use a session value of "Model" rather than "model" - see below.
<interceptor-ref name="scope">
<param name="session">Model</param>
<param name="key">partialEvent</param>
</interceptor-ref>
