I have a solution, but first...
OGNL only provides access to static fields and static methods. It cannot

Strange... because I succeeded in reading Enum values from an inner
enum class, like:
public interface MyInterface {
enum MyEnum {
MY_ENUM_VALUE;
}
}
Using
s:property value=@[EMAIL PROTECTED]
/
prints:
MY_ENUM_VALUE
(value returned by the .toString() from the Enum class)
Note: it might be dumb to do this, BUT if you use a specific Struts2
(or XWork?) converter to translate your enum value into something
different (e.g. introducing a label or something similar that would
returns My Enum Value in our example) then it's useful when not only
dealing with the Enum name (i.e. here MY_ENUM_VALUE).
I also succeeded using
s:property value=@[EMAIL PROTECTED] /
that prints:
2.718281828459045
But strangely, some:
s:property value=@[EMAIL PROTECTED]
/
does not work... why?!
... all this with Struts 2.0.11.1
However, there is a bearable solution / hack:
1. In your Constants *class*, create a public static singleton instance of
itself. Lets call it C. (Remember, OGNL can reference static fields)
public static final Constants C = new Constants();
2. [...]
And what if, as from my above explained example, you have an
*interface*, not a class...?

AFAIK, it's not working the way you excepted it to be, because this

Nested Map List type conversion properties settings
Hello,
Working on it for a while but couldn't find a solution. In my action I
need the following Map:
MapString, ListMyBean myList;
... where the class MyBean is something like:
class MyBean {
private Long id;
private String name;
// + appropriate getters/setters
}
What I'd like is setting each value back through some s:textfield /
using the particular OGNL as described here:
http://struts.apache.org/2.x/docs/type-conversion.html
For generating all the appropriate s:textfield / I have two nested
iterators; first one for the Map, second one for the List. But how do
I do with my OGNL expressions to be put in the value= attribute of
the text fields.
I'm guessing it's something like:
myList['mapKey'](beanId)
but I could not find how to configure it properly because it seems
there's a conflict between how to declare the Map conversion how to
declare the pseudo-collection index for a single myList[...] value
# conf. for the Map
Key_myList=String
Element_myList=java.util.Map
CreateIfNull_myList=true
# conf. for the Map...??? how to indicate here it's a value in the
map, not the map itself!!?
KeyProperty_myList=id
Element_myList=com.mycompany.somepackage.www.bean.MyBean
CreateIfNull_myList=true

Re: Unable to make Type Conversion work in Struts2
Thanks for your answer. I partially fixed this, noticing the square brackets notation is the same for Lists and Maps, which is not so clear on the related doc page (I posted a comment about this, having had a conversion with Dave Newton about this in a more recent thread on the mailing-list), as well as fixed the getter method which had a bad copy/paste issue. But I found another problem that might need some better formulation from me, and eventually a Jira: it seems Struts2 isn't able to fully support the java.lang.EnumMap object (e.g. using a EnumMapYourEnum, String), given that it's a particular Map (i.e. all keys are known, and they are NOT Strings) without any no-arg constructor - thus resulting in some cases in an InstanciationException. I tried some work-around with the introduction of an EnumTypeConverter (extending StrutsTypeConverter), which seemed to work fine at first sight, but unfortunately there's a buggy side effect: Struts2 then tried to convert the input value (which has to be the value of the map of type java.lang.String, if referring to the above example) ... in the corresponding Enum type of the key!!!

Evaluate a string property containing some OGNL expression
Hello,
As I wasn't able to find this out at the moment, I'm posting my question here :
Would it be possible, within Struts2 tags, to evaluate a (String)
property which contains the OGNL expression referring to an other
property??
Example :
s:set name=testValue value=%{12} /
testValue = s:property value=#testValue / // print 1
s:set name=testValueName value=%{'testValue'} /
testValueName = s:property value=#testValueName / // print testValue
testValue (via xxxName) = s:property value=%{%{#testValueName}} /
// print nothing!!!
Why I'm wanting this ?
This might be tricky but because I'm getting complex OGNL expressions like
myObj.someSubList(X).someSubMap[Y](Z).subObj.fieldName
I'd like to set my OGNL prefix with a simple set
s:set name=myPrefix
value=%{'myObj.someSubList(X).someSubMap[Y](Z).subObj.'} /
and then for each property call use something like
%{#myPrefix + 'fieldName'}
But unfortunately I'm unable to make it work at the moment.
Could please someone explain me what I'm doing wrong?
Thanks,
Maxx

Re: Evaluate a string property containing some OGNL expression
Of course the JSP if for prensentation.
But this kind of complex OGNL expression is computed as each
iteration of multiple s:iterator tags (that's why I put some X/Y/Z
variables, each resulting of a %{#someStatus.index} expression).
In fact, the myObj is exposed by the Action class through regular
getMyObj/setMyObj couple of getter/setter, and has to be used as the
target of a form.
It's just that it has a complex sub-/object hierarchy in its
structure, and this structured object is linked to some other one,
I'll call presentation structure (made of field categories,
fields...) presented in my JSP (to sum up things).

Re: [S2]Using javascript to hide a struts tag
Of course the label can't be hidden as it's not the same element. It may also depend on the theme you're using. By default it's the xhtml one, and as this theme creates additional trtd stuff around (which is really annoying and shouldn't be default IMHO), what you're doing is only hiding the inner stuff in the table. document.LocationAddNode.elements(prodIpPort).style.display = 'none'; //Does not work are you sure this expression matches your div...? I don't think so, and as you're using old-style-IE-javascript, I can only advise you to use something like this : document.getElementById(prodIpPort).style.display = none; - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
