Subject: reload the current page?
From: "David Chu" <davidchu@aol.net>
===
Given that I am in an arbitrary page in my webapp, I have a header at the
top of each page that is a toggle button for some user state.  If the user
clicks the button, I want to reload the current page, with the user state
changed.  This is tricky because the request.getHeader("referer") is
sometimes not the most recent path of the Action just performed (in the case
of Actions forwarding to other Actions).

I think one way to accomplish this is write the current requested Action's
path to a session variable, for example, "/ViewShoppingCart.do," and, if the
next action is the click of the toggle button, forward to this path again
after doing what I need to (i.e. changing user state).

The problem is I do not know how to find a reference to any given Action's
path which are defined in the struts-config.xml.  How could I access this,
or how else could I accomplish this?

Thanks for the help!

Subject: Session/Application level items disappearing when validate returns errors to page
From: "BillB" <bill.blackmon@verizon.net>
===
Hi,
I have the following declared at the top of a jsp page:
<%
// THIS SECTION IS NEVER 'SEEN' WHEN PAGE IS RETURNED WITH ERRORS......
Iterator disciplineListIt = (Iterator)
session.getAttribute("DISCIPLINE_LIST");
Iterator AGPAMemberListIt = (Iterator)
session.getAttribute("AGPA_MEMBER_LIST");
Iterator locationListIt = (Iterator) session.getAttribute("LOCATION_LIST");
Iterator membershipCategoryIt = (Iterator)
session.getAttribute("MEMBERSHIP_CATEGORY_LIST");
%>

These iterators populate different groups of checkboxes and contain bean
which contain a description and ID fields from the database.

I am using the following to fill a group of checkboxes (I know I should be
using some type of  Struts Tag but I haven't gotten that far yet - any
working, complete examples that would duplicate the following would be
greatly appreciated!).

<%
while(disciplineListIt.hasNext()) {
db = (DisciplineBean) disciplineListIt.next();
description = db.getDiscipline();
id = db.getDisciplineID();
sid = String.valueOf(id);
%>
<td align="left" width=50%>
<input type="checkbox" name="selDisciplineList" value="<%= sid %>" > <%=
description %>
</td>
<%

The output of the above and the returned selDisciplineList are exactly what
I want. However, if there
are errors when the Action forms validate method is called, all of the
checkbox groups that are created
by the above Iterators are no longer visible. I've tried making copies of
the iterators into Action form items
w/set and get methods and its the same output.

Is this a totally invalid approach using Struts or is there a much more
obvious way that I'm too blind to see
to do what I'm trying to accomplish?

Thanks,
Bill

Subject: How do I use the <html:checkbox> tag to replace of the past JSP code?
From: "news.basebeans.com" <judging.huang@intech.com.tw>

Hi,

    I used the following code to setup checkbox value and checked status
before using struts.
<%
if (arrSParameters != null) {
  for (Enumeration objEnu = arrSParameters.elements() ;
objEnu.hasMoreElements() ;) {
   objParameter = (PLSystemParameter)objEnu.nextElement();
%>
<input type="checkbox" name="parameterCode"
value="<%=objParameter.getParameterCode()%>"
<%=HTMLTools.getCheckedString(arrSPCodes,
objSParameter.getParameterCode())%>>
<%
  }
}
%>
    I used a for-loop to generate many checkboxes, and all of the
checkboxes' values are from java beans' property. Besides, I used a function
which utilize whether the specified java bean's property belong to a string
array to judge if the "checked" string was showed.

    I use the struts now. The following code is my experiment. I didn't know
how to setup the checkbox attribut to show "checked" string.
<logic:iterate id="objParameter" collection="<%= arrSParameters %>"
indexId="index">
  <html:checkbox name="objParameter" property="parameterCode" />
</logic:iterate>

    The result page didn't show the same as the result of the past code. The
struts result is follow code.
<input type="checkbox" name="parameterCode" value="on">
<input type="checkbox" name="parameterCode" value="on">
<input type="checkbox" name="parameterCode" value="on">
<input type="checkbox" name="parameterCode" value="on">
    The checkboxes's value is struts' default value "on" not the java beans'
property. I hope the result page shows the following code.
<input type="checkbox" name="parameterCode" value="WORK_START_HOUR">
<input type="checkbox" name="parameterCode" value="WORK_END_HOUR" checked>
<input type="checkbox" name="parameterCode" value="REST_START_HOUR">
<input type="checkbox" name="parameterCode" value="REST_END_HOUR" checked>
The checkboxes' values are appropriate for the java beans' property and the
"checked" string can be showed or not by condition.

    If the checkbox tag of the struts doesn't support this requirement or I
must extend the checkbox tag of the struts, please tell me, too.

Thank you very much

Subject: How to re-populate multiple selected options in a dropdown combo box
From: "Hu Ji Rong" <hujirong888@yahoo.com>

Hi,

I have the following code and String[ ] attribute with the same name in the
form bean, but got an error same bean with name stdAirspaceLimitList not
found.

       <html:select value="1000M" styleClass="txtBgManColor entryFont"
multiple="true" style="width: 157; height: 38"
property="stdAirspaceLimitList" size="2">
          <html:options property="stdAirspaceLimitList"/>
        </html:select>

What's wrong? What I want to do is select values from a non-multiple
dropdown combo box and put them into the multiple dropdown combox.

Thanks in advance.

What about request parameters and attributes? If current page before
call was

/sub-app1/action1.do?param1=value1¶m2=value2

shouldn't I also save query string? Return to /sub-app1/action1.do isn't
the same point as before call.

Why not include this functionality by default?
