user_205127.ezm (zipped)Post the relevant part of your JSP, please. I know that at least for
Struts 2.1.8.1 there is a new MultiselectInterceptor class that would
solve your problem for a select with type=multiple. There is a
CheckboxInterceptor class as well. Maybe there is none for a checkbox
array. Anyway, let us have a look at your JSP to see what S2 tags you
are using. If all else fails, you could write your own interceptor to
deal with the issue.

user_205128.ezm (zipped)I really think this is a bug in Struts 2 checkbox array behaviour!
to solve this problem I have created a variable to keep the value of the
previous selection.
if the actual selection is equals to the previous selection that means the
user want to uncheck the checkbox
this at least works, and is more straightforward than writing an interceptor
bye and thanks robert for your try!!!

user_205129.ezm (zipped)I managed to fix it.
Although the hackish alternative I presented at the end of the message
worked, when I was implementing friendly URLs it didn't work as expected for
the id parameter because it wasn't a part of <portlet:actionURL>.
I found a way to get the ID from the value stack this way
ActionContext.getContext().getValueStack().findValue("resourceId").toString();
so my final code is now
<% String resourceId =
ActionContext.getContext().getValueStack().findValue("resourceId").toString();
%>
<portlet:actionURL windowState="exclusive">
<portlet:param name="struts.portlet.action"
value="/gdocs/gdocs/moreinformation" />
<portlet:param name="docid" value="<%= resourceId %>">
</portlet:param></portlet:actionURL>
and it's working perfectly well.

Ricardo

user_205131.ezm (zipped)Hi,
I am trying t set a dynamic attribute "required" in my s:textfield
input field. It seems struts is stripping it away. Is there a way to
set a required attribute.
e.g.
<s:textfield required="true" />
generates
<input type="text" required="true" />
Any help would be appreciated.

user_205133.ezm (zipped)Hi!
I've recently started a job as a webapp developer.
I've been some days already working out how Struts 2 works, I'm the kind
of person who likes to know exactly what's going on at all moments, so I
rather assemble my own app taking what I need at every moment that work
from an example.
Is there a listing somewhere where I get a description of what exaclty
acomplishes every jar in lib folder? How they relate, which ones are not
to be used together, which ones are necessary... While i'm sure this
info is somewhere, it would be nice to have it in the same place.
This way I can add them and know why I do so, not just copy the ones
from an existing example. Also, the provided apps seem to variate a lot
in how are they done, mail reader being practically the same as the
Struts1 example.
Documentation seem to be a little scattered, I would like to see a
simple list of what every bundled jar does, not have to navigate through
all plugins, guess which ones are equivalent/deprecated/already
included, etc
Thanks!!

You can just set up a test project and add plugins you want, when you
execute mvn package you will get war with all needed libs for that
project. It's a good way to check what is needed even if you don't use
Maven 2 ;-)

user_205143.ezm (zipped)Is there a solution to support this type of tag logic:
<s:if test='%{#attr.row.department != null}'>Not
Null<br/></s:if><s:else>Null</s:else>
<s:url id='numItemsUrl' action='searchTransactionsSubmit'>
<s:param name='reportType'>ID</s:param>
<s:param name='transactionType'><s:property
value='#attr.row.transactionTypeId'/></s:param>
<s:if test='%{#attr.row.department != null}'>
<s:param name='department'><s:property
value='#attr.row.department'/></s:param>
</s:if>
</s:url>
What I find are the records where the department field outputs "Not
Null" never has the department parameter added to the numItemsUrl inside
the S:URL tag. It seems as though the S:IF is either 1) not interpreted
or 2) fails the test.
Aside from reformatting the tag layout to:
<s:if test='%{#attr.row.department != null}'>
<s:url ....>
<s:param>...</s:param>
</s:url>
</s:if>
I'm not sure what else I can do. The problem is there are 5 variables
that get added to the URL and I need to control which ones are added and
which are not added based on specific conditions and having this broken
out into 5 or 6 different if blocks to create the same URL seems
redundant when the IF tag should suffice.
Thoughts?

That still renders "&department=" on the request when the department
field is null which is not what I want. I want to not include the
parameter at all on the request if it's null.
Null = Records with department field null
Empty/Not Null = All records, not limited by department
Not Empty/Not Null = Records with the department field value
Those are the three conditions I am trying to satisfy.

Attachment:
user_205146.ezm (zipped)Although, I didn't consider this solution, which seems sort of broken
but appears to at least work and provide the desired effect:
<s:param name="%{#attr.row.department==null?'d':'department'}">
<s:property value="%{#attr.row.department}"/>
</s:param>
If the department value is null, the request parameter is named "d"
rather than "department". It is only "department" when the parameter is
not null.
I still do not understand why you cannot wrap a s:param tag with a s:if
construct to control whether a parameter is appended to the s:url or
not.
According to Eclipse, placing a s:if inside the s:url around an s:param
is not considered abnormal use of the tags, so I'm at a loss.

I understand the desire to have "pretty" urls, but technically the
presence or absence of "&department=" in the url is not distinguishable
by the action created when this url is requested.
If you're trying to distinguish between null and empty, you need a way
to signal that distinction to the action. One or two reserved
department ids/names that you interpret as these "magic" values would
solve your problem:
for example:
<s:param name="department" value="%{(#attr.row.department ==
null)?'null':(#attr.row.department.isEmpty?'unconstrained':#attr.row.department)}"/>

Hi,
i'm having trouble with token interceptor, i'm using struts 2.1.8.1 with
eclipse and glassfish V3.
***we're using struts 1 plugin*** , we're migrating an old project wich
used struts 1 and so far everything is working ok, fileupload interceptor,
forms, etc. but toke-interceptor stuff. When goin from an action to another
that is protected-affected by this token-interceptor ( the jsp has the
<s:token\> tag and the config.xml is properly configured having the
interceptor-ref token in the corresponding action) the interceptor indeed
works and interceps but it always return invalid.token result. The action
never executes as the application flow is interrupted at the interceptor
stage.
Has anybody experimented something similar? using struts 1 plugin or not?
does it have to do with this plugin and it would work using pure struts 2? (
don't ask me why but we need this up and working with the S1 plugin) , any
ideas??
Cheerz and thanks in advance,
best regards.
Manuel

user_205150.ezm (zipped)Hey,
I have a similar problem with DynaValidatorActionForm.
It says that invalid property when i have a ArrayList in the <form-property
name="searchList" type="
java.util.ArrayList"/> in the <form-bean
declaration.
Any idea?
Thanks and your help is appreciated.
