Re: Validation Random Failures
I haven't tracked it down yet, but I think it is in the type
converters. Are you using dates or decimal values on your forms?

I don't know if it has been logged as a bug. Because it happens randomly

Re: [OT] [RANT] Re: Preparable or interceptors - is there a better mailing list than this ? some thing for total newbies.
Based on your posts I get the idea you don't understand how the MVC
pattern works. I'll try to describe what should be happening.
On the browser a user submits the data he/she wishes to update. That
information is then passed to the action, I prefer to do this with an
object. So in your action you would have a public void
setAccount(Account account); method. On your form you would have fields
with names like account.id, account.description, ...
Now for this example I'm going to use the default execute method. So in
the public String execute() throws Exception {...} method your going to
have an account object. Now if you want to update this account you pass
it to your service layer which might have a method that looks like
this. accountService.update(account);
Inside the account service you'll be talking to your DAOs. So you might
have an update method in your DAO. accountDAO.update(account). Now
since your using JDBC you have control of the sql statement. So one
method of building the sql statement without having to load the account
object from the database would be to check for nulls. So say I only
wanted to update the description. Everything else is unchanged. So in
my DAO update method I would check for non-null fields and add the ones
that are not null to the sql statement. Then execute the statement.

Then why don't you simply pass the id of the account you want to
update and the fields you want to update to the action.
Then create an update SQL statement like "update account set
field1='data_from_form', field2='data2_from_form' where
id='id_from_form';"
This is a way, but not what I am looking to do. what about the
business logic layer. If I create an update statement in the Action
then no point in having an Account object. So, I created an update
statement in the business logic (Account) and passed it the new
values. The problem is, how do I get my hand on the object that I need
to update. Store it in a session ? I can not pass it back to the
action as it doesn't take any thing but string.
Why do you need to reload the account to update it? If You don't
pass an id in then you know its a new record and can issue an insert
statement instead.
I don't need to reload the Account every time I do an update, and
that's my problem in the first place.
So you mean, if the action doesn't receive an id then it must be a new
record. Right ? back again to the MVC, I need to put the logic in it's
place. I will do my best not to put any data access code in the action.
The only things you should put into a session are thing that usually
don't change very often and are session specific.
How do I resolve this then ?

I 've been trying to learn struts 2 for a week but not doing any
significant progress. I need an program that stores accounts and
services with invoices. All I need is to be able to retrieve an
account view/add invoices , and services to each invoice.
When ever, I retrieve an account I want to perform the operations
of adding or updating invoices.
Now I am able to get an account (from the DB) and to view all the
invoices, but nothing more. How do I go around this?
I have tried retrieving the account again (by its id) form the DB
but this is not what I want as it keeps on openning connection and
get every single from the DB every time I need to update. That's
why I asked if I have to use interceptors or implement Preparable
and sessionAware.
By the way, I really appreciate your help, and in many cases you
may find my post lacks some info. The reason of this is because I
am still LEARNING and I don't know what info you need to be able
to help. So if I miss some thing, just ask.

Of course you can store an object in the session. You
didn't say you wanted to.
As I said, without any information about what you're
attempting to do or if you're experiencing any
specific issues it's pretty difficult to be helpful.

Re: tks for help, but more question for html:javascript
Hmm, I've never actually used the html:javascript tag, so I'm not sure what its intended purpose is, or how it works... seems like the docs is talking about validation, so yeah, maybe it's not applicable... although, one thing I notice here... let's assume it DOES work just like a plain old tag does... om that case, the contents of your .js file might cause a problem because it's not Javascript really, it's HTML... If you make source.js just the following:function showme() { alert("pls try"); return false; }...then it MAY work... if it still doesn't, I'd not use the html:javascript tag at all, just use a plain
