Say the following form (FORM A) -- maybe representative of a shopping
cart -- is generated dynamically:

FORM A:
-
| item a | qty __  |
-
| item b | qty __  |
-
| ...   |
-
| item n | qty __  |
-

And, say the user submits the values 2,M, and 3 for items a,b and n,
respectively.  Assuming M is an invalid qty, the following form (FORM 
A,
again with error messages) gets generated:

FORM A:
ERROR:  Please fix errors marked, below.
-
| item a | qty  2  |
-
| item b | qty M  | ERROR: Invalid qty.
-
| ...   |
-
| item n | qty  3  |

How do you recommend doing this with Struts?  What class(es) should be

Re: How do you recommend doing this with Struts?

2002-05-17 Thread Ted Husted 

I'd consider adding an error property to the bean that corresponded to
each item. 

In the validate() method, you could then set the error property for
whichever item was at fault (if any), using the same key you would use
for ActionError.

On the JSP side, you can use the message tag to translate the text. 

ActionError does the same thing in bulk, but you can use the same
technique on your own.

RE: How do you recommend doing this with Struts?

2002-05-17 Thread Michael Marrotte 

One way I thought of to do this is to store any errors in the bean that
logic:iterate uses, e.g.:

logic:iterate id=jspBean name=javaBean property=javaBeanProperty
td
item bean:write name=jspBean property=item/
/td
td
qty bean:write name=jspBean property=qty/
/td
td
bean:write name=jspBean property=inputErrors/
/td
/logic:iterate

But, here I'm using the inputErrors property of the javaBeanProperty of
javaBean and I'm not using the html:error tag.  Am I cheating or missing
something in Struts that provides a consistent (more MVC) way to deal with
this.

What do you think of the above approach?  Any thoughts are greatly
appreciated?

Re: How do you recommend doing this with Struts?

2002-05-17 Thread Ted Husted 

The action:errors tag is a convenient interface to the Struts
ApplicationResources. Any component in the application is welcome to use
the ApplicationResources (hence the application moniker).

What you might want to do is save the message key in the inputErrors
property and then use bean:message to write it out. This will make it a
drop-in replacement for action:errors.

Re: How do you recommend doing this with Struts?

2002-05-17 Thread Ted Husted 

Validation errors actually *belong* to the model, so yes. 

The error messages are coming out of the ApplicationResources. This is a
standard Properties file and part of the standard approach to i18n in
any Java application. Ideally, these should be shared with any other
application that is doing the same sort of thing. Say something in Swing
or JavaServer Faces. 

All content, including messages, really belong to the model.
Conceptually, there's no difference between a paragraph of text and a
memo field in the database. It's all model; it's all message.

The view's job to format the content so that it can be displayed in the
chosen medium. But the view does not own the content -- it owns the
markup that surrounds the content. As a practical matter, we end up
mixing static text into HTML and JSP files these days. But not because
we ~want~ to. 

IMHO, the ActionForm is a controller component and not part of the view.
It lives on the layer between the view and model, and so can be bound
with either and both.

RE: How do you recommend doing this with Struts?

2002-05-17 Thread Michael Marrotte 

Isn't the message key mandatory for the bean:message, according to the TLD?
So how can the key be set from a bean property?

These other two approaches work.  But, I don't think this is exaclty what
you meant:

1.) bean:write name=jspBean property=inputError/

2.) logic:equal name=jspBean property=inputError value=true
bean:message key=error.qty/
/logic:equal

How can I do this with bean:message?  I want to write:

bean:message name=jspBean property=inputError /

But, I get the error about the mandatory key required.

Thanks,

RE: How do you recommend doing this with Struts?

2002-05-17 Thread Michael Marrotte 

Ted,

I got it working your way, i.e. with bean:message...  But, I had to modify
the TLD (struts-bean.tld).  I modified the key attribute and added name and
property attributes.

attribute
namekey/name
requiredfalse/required
rtexprvaluetrue/rtexprvalue
/attribute
attribute
namename/name
requiredfalse/required
rtexprvaluetrue/rtexprvalue
/attribute
attribute
nameproperty/name
requiredfalse/required
rtexprvaluetrue/rtexprvalue
/attribute
attribute

Is it common practice to modify the TLD's for the Struts tags?

Isn't the message key mandatory for the bean:message, according to the TLD?
So how can the key be set from a bean property?

These other two approaches work.  But, I don't think this is exaclty what
you meant:

1.) bean:write name=jspBean property=inputError/

2.) logic:equal name=jspBean property=inputError value=true
bean:message key=error.qty/
/logic:equal

How can I do this with bean:message?  I want to write:

bean:message name=jspBean property=inputError /

But, I get the error about the mandatory key required.

Thanks,

--Michael Marrotte

The action:errors tag is a convenient interface to the Struts
ApplicationResources. Any component in the application is welcome to use
the ApplicationResources (hence the application moniker).

What you might want to do is save the message key in the inputErrors
property and then use bean:message to write it out. This will make it a
drop-in replacement for action:errors.

 One way I thought of to do this is to store any errors in the bean that
 logic:iterate uses, e.g.:

 logic:iterate id=jspBean name=javaBean
property=javaBeanProperty
 td
 item bean:write name=jspBean property=item/
 /td
 td
 qty bean:write name=jspBean property=qty/
 /td
 td
 bean:write name=jspBean
property=inputErrors/
 /td
 /logic:iterate

 But, here I'm using the inputErrors property of the javaBeanProperty
of
 javaBean and I'm not using the html:error tag.  Am I cheating or
missing
 something in Struts that provides a consistent (more MVC) way to deal with
 this.

 What do you think of the above approach?  Any thoughts are greatly
 appreciated?

 Thanks in advance,

 Read the JavaDocs on ActionError, ActionErrors, and the html:error tag. I
 think you'll find that you can position error messages next to the user
 value that is incorrect.

 Say the following form (FORM A) -- maybe representative of a shopping
 cart -- is generated dynamically:
 
 FORM A:
 -
 | item a | qty __  |
 -
 | item b | qty __  |
 -
 | ...   |
 -
 | item n | qty __  |
 -
 
 And, say the user submits the values 2,M, and 3 for items a,b and n,
 respectively.  Assuming M is an invalid qty, the following form (FORM
 A,
 again with error messages) gets generated:
 
 FORM A:
 ERROR:  Please fix errors marked, below.
 -
 | item a | qty  2  |
 -
 | item b | qty M  | ERROR: Invalid qty.
 -
 | ...   |
 -
 | item n | qty  3  |
 -
 
 How do you recommend doing this with Struts?  What class(es) should be
 used?
 How can errors be stored and retrieved dynamically?

RE: How do you recommend doing this with Struts?

2002-05-17 Thread Michael Marrotte 

Suppose the qty values were HTML select's.  How would you recommend I
reset there values on error, e.g. 2,M,3, below is shown in the second form.

Any help is greatly appreciated.

Thanks,

I'd consider adding an error property to the bean that corresponded to
each item.

In the validate() method, you could then set the error property for
whichever item was at fault (if any), using the same key you would use
for ActionError.

On the JSP side, you can use the message tag to translate the text.

ActionError does the same thing in bulk, but you can use the same
technique on your own.

 The ActionErrors work great for static pages.  But, the rows in my example
 are dynamic.  How do I name them in say an logic:iterate tag.  Or,
better
 yet is there a straightforward or best-practice way to handle this with
 Struts?

 Thanks,
