Question regarding Tags and the release() method
Hi all,
It's probably not a bug, but I can't figure it out.
I wrote a Tag that inherit from BaseHandlerTag. The
onclick (per example) property of the BaseHandlerTag
is only reseted in the BaseHandlerTag release()
method.
The problem is that the release method is called
only when the container wants to release a tag. In
Tomcat that will happen if the TagPool is already
full. The point is that release() is not called
between usage. That means the onclick property is
never reseted between usage?!
In my tag I need to add something to the onclick
property .. so it get bigger at each call. For the
sake of clarity :-) Here is a part of my code.
...
String origOnClick = this.getOnclick();
if (origOnClick == null) {
origOnClick = "";
}
...
this.setOnclick(origOnClick + ";" + jsCall +
"disableAllSubmitButton();this.form.submit();");
I found this on the net regarding the proper use of
the release() method
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16001
It seem clear that in Tomcat it will stick to the
spec.
I know, I can reset the BaseHandlerTag properties in
my Tag ... but for what I understand so far there is a
bug in the BaseHandlerTag. The BaseHandlerTag should
reset is properties in the doStartTag() method.
Is anywone can point me where I'm wrong ... It seems
to big to be a bug ...
Thanks for your help
/David

Oki, let say the user double click on the submit button, so you have request A and Request B. A is valid and is been processed when B reach the server. The session ActionForm is populated with B's data while A is still processing the same bean. You have a race and there is no way to avoid it.

Re: Token in struts and session bean.... problem with the framework ?
Hi all thanks for your answers. I was indeed talking about ActionForm (sorry we use to call that a bean here :-)). What I understand from our discussion is: -Thant I Can use javascript to avoid duplicate submit: Works well when deployed in a trusted environment like intranet. (But no server side protection...) -There is no way to avoid ActionForm with session scope to be populated with data comming from an invalid request (with a bad token). -To solve that I can subclass the request processor. -Maybe I can use web filter ... but i don't think I will have access to all struts ressources. I think the best way to handle the problem on the server is to have a Handler (Something that can work as Exception Handler works in Struts 1.1. ) called by the struts framework prior to populate the bean. This handler can do any checks like checking if the user is logged or checking if a valid token in the request is present :-). Anyway, thanks for you help! /David > > >It's up to your Action to call the token methods to validate the > > >token and forward the user to an appropriate page. > > > > > > I know, maybe I wasn't clear enough .. sorry :-) >What I'm saying is that if you use a > session bean, the content is modified even though the >token is invalid.. I thinks this should not happen. By session bean, do you mean EJB or an ActionForm stored in the session? I haven't tried this but maybe you could put the token check in the form's validate method but that also happens after the form bean is populated. The token is currently viewed as a piece of form data for the Action to handle and not the framework. Allowing actions to check the token gives people the flexibility of deciding what to do with the user in various situations.

Token in struts and session bean.... problem with the framework ?
Hi all, If you have a session bean and you are using the token framework to protect yourself again multiple submit... Let say a request with a bad token is post to the server. The bean will be populated right ... even if the token is not valid. Is struts offers support to check if a request contains a valid token prior to populate the bean. For what I know you the sooner you can play with token in struts is in the reset method of the bean (It may not be the best place to play with token anyway...). Is a request with a bad or no token should be redirect by the framework to a handler. Like it's done with the Exception in Struts? I think there should have a way to avoid changing the server state on bad request ... My guest is that you already know about all that :-) ... or that there is something to prevent this that I'm not aware of. Thanks for your help /Dave __ Do you Yahoo!? SBC Yahoo!

RE: ActionError not supporting bundle
Hi, Honestly I haven't try a solution yet .. just a lack of time. I had a chat with a guy on the list his workaround was to put all bundle in the main bundle at boot time (means he was keeping all his bundle files but was merging them dynamically). For me it seems pretty clear that ActionError should support specifying bundle since it's when you specify a key that you know where this key is coming from. I'll try to dig a solution on my own during next week and let know my solution as well. Just one question left .. is this limitation just because someone forgot about it ... or because havin ActionError supporting bundle is much more complicated than what I think right now ?

I know the JSP errors tag allows to specify the bundle ... the problem is
that the errors to display may come from different bundles. Per example, in
the validate Method of an ActionForm you may have:
if (f1 == null)
errors.add("f1", new ActionError( "bundle1.f1.notEmpty"));
if (f2 == null)
errors.add("f2", new ActionError( "bundle2.f2.notEmpty"));
where bundle1.f1.notEmpty comes from "bundle1" and bundle2.f2.notEmpty comes
from "bundle2".
This case will occur if you have a base bundle where you put your general
messages and a module specific bundle where you put stuff specific to your
module.
And in the JSP you can only specify one bundle... so you got a problem.
In validator it's the same problem:
You have basic messages used by the different validators and most of those
messages take an argument which is the name of the field that is validated.
So my basic messages are in the main bundle and the field names are in the
module specific bundle. The result is that I can't have the field name
appear on the screen.
Hope it's more clear .. if not tell me :-)
Thanks again

OT: SQL statement generator for a web based list
Hi all, Sorry to bug the list for that .. I looked around and haven't found my answer . and pretty sure you guys had this problem already. My web application support lists. Searches on the list can be done by specifying several parameters .. like ID, Country, name .. whatever. From those parameters I must craft an sql statement on the fly to fetch the info from the db. Is there a framework that I can help me in this task . I did it myselft .. work well . but the result code is complex .. I think an adapted framework will help simplying the problem. Thanks /David
ActionError not supporting bundle
Hi all, I look into the RC1 code to find that ActionError doesn't allow to specify the bundle to search for a given error message. I my application I have multiple modules and multiple message ressource files. How can I specify error messages coming from different bundles? The Errors Tag doesn't support to specify a bundle too. I initially got this problem in validator. I put my generic error messages in the base message resource file and the column name in a specific module. So I guess you are already aware of the problem ... it seem to be a big limitation if I want to use multiple resource files :-/ I just want to know if this is planned to be fixed in Struts 1.1? If not I suppose the only work around is to use only one property file ... for the whole application ... but that gone be a huge file ... is that a problem. Do you have any solution I haven't think of ? Thanks for your help ! Best Regards /David
