user_189427.ezm (zipped)So I tried the "param." access path last night. That wasn't working, the
documentation referenced a "parameters." instead. I managed to get that working
with s:component, but no luck with s:include.
I don't really care if I use component versus include; however I liked the
include slightly better since I was easily able to place my jsp
fragment/component underneath WEB-INF. When I tried using struts.ui.templateDir
to move the template directory used by s:component under WEB-INF, it appears to
break all the regular struts 2 tags. Is there a good way of locating
application custom templates underneath WEB-INF without breaking the search path
for the existing tag/themes?

dojo.event.topic.subscribe("/afterDeleteLaw", function(data, request,
widget){
//data : text returned from request(the html) It is my json
//request: XMLHttpRequest object
//widget: widget that published the topic
var _mydata = eval("(" + data +")");
});
and:
<s:a id="idOfMyAnchor" showLoadingText="false"
targets="%{'linkattachedMainDocRow' + #document.count}"
theme="ajax" href="%{#deleteDocumentAction}"
notifyTopics="/afterDeleteLaw">
<s:url value= "/>
</s:a>
It is impossible to get id of widget. I've parsed object, it contains
fields connected with response, also it has field with data value (parameter
data).
Seems like it's useless to get id of widget that fired event.

That is good news! When presented with a new framework to consider, easily
being able to present a dynamic web page is sort of a big deal.:rules: If
you look across the attributes/docs on the struts tags you find the primary
attributes key, name and id are sprinkled around placing the developer at
the mercy of trial and error. I seriously wonder if the best bet would be
to delete any struts custom tag that overlaps with JSTL and keep only those
integral to the framework itself. The StrutsRequestWrapper is already
making OGNL "JSTL friendly" and most of the time consuming riffraff has to
do with the bloody web page!
Look at how Struts Classic custom tags overlapped JSTL and all the confusion
that caused!
Peace,
Scott

Hi,
I need to test in jsp if some session variable is present, and based on that
to
show some struts view code or not. How can I do that ?

Hi Milan,
If you're using Struts 1 you should be able to use the logic:present tag
like this:
<logic:present name = "NameOfVariableSavedInSession" scope = "session">
<tags to execute if the above is true....
</logic:present>
Hope this helps!

user_189433.ezm (zipped)Hello,
As per spring documentation, it is said that whenever an exception occurs,
spring framework would eventually rollback transaction, if any active is
present. I am using spring in combination with S2 and I do map all the
exceptions taking the user to error page. I am just wondering if when
working with the combination, the transactions are rolled back upon
occurance of exception.

user_189435.ezm (zipped)Hi everyone!
I've just started learning Struts (1) and this is my current problem:
I have a
java.util.Set which is saved in the current session and I'm trying
to use Struts for checking if it's not empty and in that case iterating
through it (from a JSP). This is the beginning of that code:
<logic:notEmpty scope = "session" name = "skillsFound">
<logic:iterate collection = "skillsFound" id= "thisSkill" scope
= "session">
When I try stepping through the code, the logic:notEmpty tag is handled just
fine, but when I get to the logic:iterate tag I get this exception:
javax.servlet.jsp.JspException: Cannot create iterator for this collection
Does anyone know if it's possible to iterate through a Set using Struts (1
and not 2) in any way?
I could always make it work by writing a scriptlet and iterate through it
the regular Java way, but I'm trying to use as much Struts as possible since
I'm doing a thesis where one of the issues is what the benefits of Struts
are. (And besides, I've read that using scriptlets is "bad style" nowadays.)
So if anybody knows a Struts solution to this, I'd be very grateful!
Thanks in advance!

iterate over the List?

user_189437.ezm (zipped)Yes, I suppose I could do that but then I consider that a drawback of Struts.
Is there no other way?
If there isn't, I think I'd rather use a scriptlet no matter how bad it
looks.. (It's also because I'm doing this "Struts project" like a new
version of a project where I didn't use Struts and in that project I didn't
have to transform my Sets.)

user_189438.ezm (zipped)If this is new development, I don't understand why you would deliberately
choose Struts 1 over Struts 2. Unless your goal is to prove that Struts has
too many drawbacks to use.

user_189439.ezm (zipped)If you want to go that way but
Set extends Collection
http://publib.boulder.ibm.com/infocenter/wsadhelp/v5r1m2/index.jsp?topic=/com.sun.api.doc/java/util/Set.html
Collection supports iterator() method which returns an iterator()
Iterator iterator()which you can use to iterate thru the collection
Iterator iterator = MySet.iterator()
http://publib.boulder.ibm.com/infocenter/wsadhelp/v5r1m2/index.jsp?topic=/com.sun.api.doc/java/util/Set.html
e.g.
while (iterator.hasNext())
{
Object obj = iterator.next();
}
?
