Re: repost: validator & retrieving data
I don't know if the proposal of Anant works. I know my proposal works well.
You must use the same bean in the page "proccess" and the page "prepare".
For e.g.
<action path="/prepare"
type="xxxx"
name="bean"
scope="request">
<forward name="success" path="Process.jsp"/>
</action>
<action path="/process"
type="xxxx"
name="bean"
scope="request"
input="/prepare.jsp"
validate="true">
<forward name="success" path="Main.jsp"/>
</action>

Sorry there was a typo in last one
Hi,
You don't need to have two actions but you can have different mappings
for the same action class
For e.g.
<action name="formbean" path="abcdisplay" type="AbcAction.java" >
<forward name="success" path="jsp name" />
</action>
<action name="formbean" path="abcProcess" type="AbcAction.java"
validate="true" input="abcErrorShow">
<forward name="success" path="results jsp" />
</action>
<action name="formbean" path="abcErrorShow" type="AbcAction.java">
<forward name="success" path="jsp name" />
</action>
Now in the action class use
If(mapping.getPath().equals(abcdisplay)){
Get data from backend
}
Else if(mapping.getPath().equals(abcProcess)){
Process data from backend
}
Else if(mapping.getPath().equals(abcErrorShow)){
Populate data from form bean itself
}
Regards
Anant

Subject: repost: validator & retrieving data
I'm sorry but nobody answered my question...
Could somebody help me?
I'm using validator for my pages. Searching the mailing list I found
that I should use 2 actions:
"If there are 2 actions, one to "prepare" the page and one to "process"
the user input, we define the input attribute value of the "process"
action mapping to be the URL of the "prepare" action."
I think it's right, but now I have this problem:
The "prepare" page retrieves data from the db. If validation fails, the
user is forwarded from the "process" action to the "prepare" action. In
this case I don't want to retrieve data from the db, but leave what
the user entered before. In other words I want to retrieve data only if
the user asked for the "prepare" action, not when he is redirected to
the "prepare" action from the input property of "process" action.
Is there a way to do that?
The only way i found is an hidden field, but I don't like it...

Re: R: repost: validator & retrieving data
Posted by Hubert Rabago <ja...@yahoo.com>.
The values that you read from the DB need to come from somewhere.
Perhaps you can store them in a session attribute (then clear it once the
form passes validation). Oh, yeah, an action has to prepare them, so maybe
you can use the same action, except that before it reads from the DB, it
checks if the values are already available from session attributes.

R: repost: validator & retrieving data
Posted by Leonardo Francalanci <lf...@simtel.ie>.
I don't think I made myself clear.
I can't set the input of the "process" action to the jsp of the prepare
action because in the prepare action I get data from the db to
fill a listbox.
If I used your solution in case of a validation error my list box
would not be filled.
But if I set the input to the "prepare" action the values the user entered
would be resetted to the values in the db.
That's way I need to know, in the prepare action, if I'm coming
from a validation error or a simple "GET".
Did I make myself clearer?
Thank you
