ParameterNameAware issue
Hi, I am trying to upgrade my application from 2.3.15.2 to 2.3.16.3. Some of my actions implement the ParameterNameAware interface to check if a parameter will be accepted. I have parameters of the form like user.username (e.g. loginform) which will be passed to the acceptableParameterName(String) function of the LoginAction class. The LoginAction has a User Object with a setUsername method. I didn't want to use the model-driven approach. When upgrading to struts 2.3.16.3 the acceptableParameterName function is getting called multiple times with different combinations: user.username, user and username. Is it wrong to use dots in parameter names? Any suggestions?

Re: Hibernate problem with OGNL
Hi,
I have situations, where the getId() method of my model class returns null
when navigating through OGNL e.g. when
calling s:property value=#user.gallery.id/.
Have you tried s:property value=user.gallery.id/ or s:property
value=%{user.gallery.id}/
No luck :-(
I also tried with JSTL now without success.
It's very strange, since sometimes it works and then it reappears again.
I'll ask at the hibernate forum.
Regards,
Markus

Re: Hibernate problem with OGNL
Hi,
I think I've found the problem.
I had javassist 3.17.1 (latest) in my project but hibernate 4.2 ships
with version 3.15.0
Now it seems to work!
Thank you, and sorry for misplacing my question here!

Markus

I've seen this behavior on newly created instances. Hibernate doesn't
know the ID until the object is persisted to the DB. Hibernate tries
to delay this as long as possible to minimise DB writes. You would
have thought a request for the ID would force a DB write but Hibernate
doesn't seem to implement this behavior. If you want the ID you need
to force the DB write first.

Hibernate problem with OGNL
Hi,
I don't know if this is the right place to ask, but maybe there is
anyone who has experienced the same problem.
I'm using Struts2 (latest version), with Hibernate (latest version)
My database models all have getId().
I have situations, where the getId() method of my model class returns
null when navigating through OGNL e.g. when
calling s:property value=#user.gallery.id/.
When I call getId() from the method in my action class (e.g.
UserListAction iterating though users and calling
user.getGallery().getId()), it returns the id as expected.
If I do that first in my action class, then also my s:property.../
renders the id as expected; so I thought about a lazy loading issue...
all my getId() methods are public, NOT final, and the Long id members
are protected.
I also tried to add a getMyId() method in the model which calls getId()
from within the same class.
getMyId() { return getId(); }
This surprisingly works and outputs the correct id when calling
s:property value=#user.gallery.myId/
Did anyone experience something simliar or has any suggestions?
OGNL 3.0.6, Hibernate 4.2, Struts 2.3.12
Thanks,
Markus

Re: Struts2
Hi,
you have no result named success for your user action defined in
struts.xml, but you return success in your execute method.
also check the case sensitivity of login.jsp and Login.jsp defined
as result.

Re: nested property tag in action tag
ok, for now I got it working by doing it in this way: s:action name=myAction var=#myAction / s:property value=#myAction.myProperty/ the thing is that I use the OpenSessionInView pattern with hibernate, so I get lazy exceptions here since the action already executed (now I prepared my specific properties in non lazy mode). I'm doing so, beacause I need the computation of another action (or other actions) to show some common things (e.g. an account summary shown in the left column for every action in the /account namespace) while executing my action without needing to provide a custom view for every call of s:action..., so I thought I could put it inline. regards, markus Am 21.03.2012 02:17, schrieb vEnkaTa mohAna rAo SriperumbUdUru: I think, you need to reconsider your design let us what you want to do? why are you doing so?

Call a function after invocation but before jsp rendering
hi there, my application uses struts2 (latest version), siles with JSP and hibernate. what I am trying to do is to call a method after the action has been executed, but before the JSP is getting rendered. to be concrete, I want to call a createTitle() method which is common for all my actions (extending BaseAction with a default implementation of createTitle()), but when I use an Interceptor for that and call it after the action invocation, the JSP has already been rendered. So my question is, at which point is the JSP rendered? can I do something between? since I want to be able to set the title according to eventual errors, I cannot do that before the action invocation. any suggestions? thanks, markus - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org

XML Validation and slashes in action name
Hello, I have slashes in my Action names, e.g. ModelName/save What I want to do is to add validation only for the save action. As far as I understand, I can create a validation file specifically for the action name, and not for the method to be invoked. ModelAction-save-validation.xml does not seem to work. ModelAction-ModelName_save-validation.xml neither works. Is there any workaround? Or do I have to change my action names?

Keep Objects over request
Hi all! I'm looking for a convenience way to keep an Object over a single request. I know that i could put it into the session and remove it afterwards, but is there another way to handle this, without needing to remove it explicitely? For those who know Symfony (php framework) there is a setFlash(..) method which keeps objects alive over a request and deletes them afterwards. Is there something similar in Struts (ver.1) or some approach? Thank you, Markus - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
