Re: Unit Testing Actions with Annotation based validation in Struts 2.1.6
I've figured how to do it! You need to use the container properly to populate all the fields with @Inject annotated setters. It's another reason why I don't like auto-wiring. I know it's powerful and when you're familiar with the codebase it's simple but it makes stepping through the code a nightmare as object creation and population is done by voodoo. If anyones is interested let me know and I'll post the code.

Re: action class is a part of controller or model; and what about formBean
Well i would say, tha action implementation (action class) is the controller, formBean is in one way the interface between view and controller and model is implementation of some third part (f.e. hibernate)... Thats my view of the 'story'. If i'm wrong, please correct me.

And here is the part of my login.jsp that uses this custom tag:
--
%@ taglib prefix=t tagdir=/WEB-INF/tags %
...
s:form action=login
...
t:formField fieldName=password required=true
labelKey=msgkey.label.password
input type=password id=password name=password/
TODO: Forgot your password?
/t:formField
...
/s:form

Suppose action has a property 'fieldName' and I need to get value of a tag
attribute w/ the same name. I get tag atribute using s:property
value=%{#attr.fieldName}/. The issue here is: if jsp page that uses this
custom tag does not provide value for 'fieldName' attribute, then
s:property value=%{#attr.fieldName}/ will return value of action
property 'fieldName'.
I did not found where jsp tag stored its attribute, but it seemed like in
PageContext.
I tried to get PageContext, but ActionContext returns 'null'. Here is my
Java code:
PageContext pageContext = ServletActionContext.getPageContext();
if (pageContext != null)
{
log.debug(pageContext.findAttribute('fieldName'): +
pageContext.findAttribute(fieldName));
}

Conversion problem for bi-dimensional Lists and Arrays
Hi all, I want to send a bidimensional List and/or a bidimensional array from my application's view to the action. For example, I have a generixMatrix object in the action (with getters and setters of course). The genericMatrix should be able to hold any kind of object. I want to set a 'Currency' object's 'value' field from the view, using an input name=OGNL expression value=theValue My problem is that i cannot address the Currency object properly with OGNL, or Struts does a bad type conversion. I tried to represent a currencyMatrix that holds Currency objects 1) In the action: ListListCurrency currencyMatrix In the view: currencyMatrix[0][1].value (currencyMatrix[0])[1].value currencyMatrix.get(0).get(1) None of these are working. I debugged and noticed that currencyMatrix gets initialized, but instead of RowDTOCurrency elements, all its elements are null. 2) In the action ListRowDTOCurrency currencyMatrix where RowDTOT represents a row, having a field ListT rowElements In the view: currencyMatrix[0].rowElements[1].value Same as above, currencyMatrix is filled with null elements 3)In the action: ListcurrencyRowDTO currencyMatrix and RowDTO has a typed list ListCurrency currencyRowElements. It works, but it does not help me. This forces me to create a new row object each time, like personRowDTO, anotherRowDTO etc. Struts2 documentation specifies that the Struts 2 type conversion mechanism can use generics-based typing to learn the correct target type for the conversions, but I think it defects when having nested generic types. I also tried using a bidimensional array like Currency[][] but again I cannot find a way to reffer to it with OGNL. I am open to any suggestions. To make a long story short, all I need is a sollution for a matrix-like object that can hold any type of object Thanks you in advance -- Damian - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org

Re: How to get value of tag attribute from OGNL?
The answer is easier if this .tag file contains no recursive calls.
The issue is that the .tag file receives attributes through jstl-el, not
ognl. You can use the jstl-el c:set tag to promote that value into a
namespace that's also accessible from ognl.

Passing List with Redirect
Hi All
I'm wondering if theres a way to pass a list of values as a
parameter in a redirectAction. For instance:
action name=WorkAction class=test.WorkAction
result name=success type=redirectAction
param name=actionNameViewAction/param
param name=myList${myList}/param
param name=myProperty${myProperty}/param
/result
/action
In this case, myList is an array list that is populated in
WorkAction. ViewAction then has a setter for an Array List of the same
name. myProperty is just a string.
This doesn't work as it stands, I get a string representation of the
array instead of the array passed. So in the ViewAction instead of a 2
item array, I get a single item array with a string like:
[TEST A, TEST B]
While this is certainly parsable, I was wondering if theres a way to
handle this with something already built into struts. I'm also aware
that it's possible to solve this using the session, but I was curious if
theres a way to avoid doing it that way.
Thanks,
Tim O

Re: Changing the border color of a text field
You could use 'addFieldError' in your action class for the zipcode
field that contains the error. Then use the 'cssErrorClass' attribute
in the s:textfield tag to change the display of the 'error' textfield.
Each of your textfields will have to have a unique name in order to
add the field error.
Eg:
addFieldError(zipcode1);
s:textfield name='zipcode1' cssErrorClass='errorClass' /
The errorClass would have CSS attributes to change the color, etc.

Re: How to get value of tag attribute from OGNL?
Why are scriptlets an evil? Is it relates to an architectural aspect that
View (JSP) must contain no business logic? Or something else? BTW sometimes
OGNL also contains little complex code. What about this one:
s:set var=label value=%{#attr.labelKey != null ?
getText(#attr.labelKey) : (#attr.label != null ? #attr.label : '')}/
It is not so kind to deal w/ code like that((. But what to do? Add one more
function to *Action class?

Re: Changing the border color of a text field
I am confused about what getter are you using for String[] zipCode = new
zipCode[10]; Is it 'getZipCode' or 'getZipCodeList'? If 'getZipCodeList'
then try this one:
s:iterator value=zipCodeList var=Zcode status=rowstatus
...
s:set var=zipCodeErrors value=%{fieldErrors['zipCodeList[' +
#rowstatus.index + ']']}/
...
/s:iterator
james billa wrote:
Alex, It is a great idea. But still I haven't got it working.
value=%{fieldErrors['zipCode[

How to connect the error in action to the field on the screen (Again

Re: How to get value of tag attribute from OGNL?
trust me, that is nothing compared to what I have seen in scriptlets.
That expression could be broken down into an if block, even the
original is not that hard to read. Assuming you don't put any business
logic in scriplets, which is evil by definition (an axiom I guess),
pages containing scriptlets are very hard to read, maintain, and of
course debug. Even reading your own scriptlets will be hard 6 months
after you write them. Whenever you think you need an scriptlet, double
check, there is a very high chance that you have other, cleaner, ways
of doing the same thing.
that's of course my very own personal opinion :)

that's only a problem for defining maps in ognl, which used the
#{a:b} syntax, which made the jstl el complain. The solution is just
to use the alternative map syntax:

I have the following class:

private String content;
private String type;
private ListAnswer answers = new ArrayListAnswer();
.
}
And class answer:
public class Answer implements Serializable{
private Integer id;
private String content;
}
I would like to iterate over the questions, and for each one display the
option to choose the answer in a radio button.
In the action class I have the followings:
ListQuestion videoQuestion = ... (I get it from the database).
List answers;
I wrote the following code:
s:iterate value=questions status=pos var=question
s:property value=#question.content /
s:radio name=answer[#pos.index] list=#question.answers listKey=id
listValue=content /
/s:iterate
But I get an error message:
Error on line 25, column 9 in template/simple/radiomap.ftl

It cannot be assigned to itemKey
The problematic instruction:
--

why is it? I have getter and setter for id and content parameters of class

As well, how can I retrieve the answers in the best way?

the problem was that i didn't have a get method for id and content.
Now my question is:
when i run the page, the source code writes the radio buttons like this:
input type=radio name=answer[#pos.index]
id=getFirstVideo_answer_#pos_index_5 value=5/
what i need it to save the answer for each question.
how can i do it?
what variable do i have to declare in the action class and how do i
