html:options

[sjones]

Good Morning Everyone.

I have a List object and i need my JSP page
to build a drop down list box using the List as the source
for the options.

I can do it with a scriplet but i need to one of the struts tags



can anyone help me with use one of these tags.

I am looking at the java.docs but it doesn't really help me.

the List is also accessible from a classs name EqualityOperators

List o = EqualityOperators.getOperators();

hi!
i have the following scenario
in my database i have an Agency table(which includes the attribute 
AGENCY_ID) and a Client tables(which includes a AGENCY_ID that maps to the 
id in the Agency table)
agencies are created first through a web interface.
after that you create Clients. what i want is that when you are filling in 
the details for the client, i want  a drop down list that includes the 
AGENCY_ID of all agencies that are in the database. so the person fiiling in 
the info can select a particular AGENCY_ID for that client)
right now in my ClientForm, i have an int agencyId. i want this populated on 
the basis of the selection made form the drop down list.

how do i do this? any suggestions?
i'm thinking of  reading all agencies, chucking them into a collection, 
placing the collection in the session context and then reading off it in the 
jsp page using html:options

The downside to that is that my ClientAction forwrads to client.jsp(where 
you add client details). And i do not particularly want to put all the 
Agency reading bit into ClientAction.
I could use a separate Java class, but i have an action DisplayAgency that 
reads all the agencies from the database, adds them to a User bean, puts 
this in session context and later the page this action forwards to uses 
logic:iterate to move through the collection in the User bean and display 
it. Having another Java class to read only the id's and put them in a 
collection and place this in sesision seems like duplicatng an existing 
task(with sme minor differences)

are there any other ways of doing this?

thanks
cheers

[Doug Dates]

I want to display a dropdown list. The list items are "By First Name", "By
Last Name", "By Date". I think I can do it by the following way:


 By First Name 
 By Last Name 
 By Date 


Is there any disadvantages to use above approach compared with using
? If I use  instead of using above
individual ,as following:


  


where should I set myArrayList? in init method of my servlet class, or in my
action form bean, or somewhere else? I am not quite understand it. Could
some one please help me?

Thank you

html:options

[tsawyer]

Hi,

We're trying to use the html:options tag (struts 1.0.2) to render a drop list 
containing the values from a String Tokenizer, which is tokenizing a comma delimited 
string.  We just want a drop list that contains each of the values in the list, with 
the value and description identical.

The behaviour we are seeing is that we are getting half the number of options, because 
the code is sticking the first value from the list as the value, then the second as 
the description, then the third as the second value, and the forth as the second 
description. 

This would appear to be bourne out by this code from the tag itself:

  // Otherwise, use the separate iterators mode to render options
else {

  // Construct iterators for the values and labels collections
  Iterator valuesIterator = getIterator(name, property);
  Iterator labelsIterator = null;
  if ((labelName == null) && (labelProperty == null))
  labelsIterator = getIterator(name, property); // Same coll.
  else
  labelsIterator = getIterator(labelName, labelProperty);

  // Render the options tags for each element of the values coll.
  while (valuesIterator.hasNext()) {
  String value = valuesIterator.next().toString();
  String label = value;
  if (labelsIterator.hasNext())
  label = labelsIterator.next().toString();
  addOption(sb, value, label,
selectTag.isMatched(value));
  }
}

It's using the same iterator for labels and values, and doing a next() twice per row.

Is this a bug?  Am I missing something obvious?

Cheers,

Tim.

[Yuriy Zubarev]

Hello everyone,

I have a property "countriesList" of "userForm" bean
which itself a list of beans which contain "code" and
"description" properties. And I need to display a listbox
populated with list of countries. The only way I made it work is:







And I was wonderion if it's possible to get rid of bean:define
tag and use just html:options facilities to render needed information.

As I undestood from struts documentation, I shouldn't use "collection"
attribute in this case and use "name" and "property" (and combination
of "labelName" and "labelProperty"). But no matter what I tried
I always got an error page.

Thank you for your time.

Best of luck,
Yuriy Zubarev

I have a collection of java.lang.String objects.  How do I get the

My code is :

 <%
try{

//I know this is where things are breaking I have tried serval
variations to no avail
%>
 
<%}catch (Exception h){
h.printStackTrace();  //because things don't work... this might give a

[Luke Studley]

Hi all

This is my first post - so excuse me if it is really basic but I am trying
to get the html:options tag to work as documented. My code looks like:



nameTitles.put("Mr",null);
nameTitles.put("Mrs",null);
nameTitles.put("Miss",null);



.




Where I am declaring a simple map and then trying to use it to populate the
option list. But I get the following error:

javax.servlet.jsp.JspException: No getter method available for property
personTitle for bean under name org.apache.struts.taglib.html.BEAN
at
org.apache.struts.taglib.template.GetTag.doStartTag(GetTag.java:193)
at org.apache.jsp.pagetempl$jsp._jspService(pagetempl$jsp.java:265)
at
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107)


What am I doing wrong???!

Hi,
 
I want in my drop down a blank record. This needs to be the default. This provides the 
user an option to not select anything( It is a null field). 
 
Is it possible to do this other than putting an empty string in the collection. How to 
set this blank string as the default(not affecting the user's selected value in the 
edit mode)? 
 
I hope I am clear.

Re: html:options

[Jeff Kyser]

name/value pairs from a database are handled nicely
in a list of LabelValueBeans.
I'd pull the code to load that list from the database out
into a model class, or perhaps into a Singleton loaded
by an InitServlet (at startup - if the contents weren't
changing, or were at least application-wide)
Then let your actions access the application-scoped
AgencyList instead of doing the work themselves.
And you can iterate the AgencyList in your JSPs,
dealing with both names and values, or just values -
whatever you want.

hi!
thanks for that.
no the values are not application wide, they may change depending on the

LabelValueBean sounds like an excellent idea

Html:Options usage

[e gg]

Hi, I have a bean class that returns an ArrayList of ArrayLists for my dropdowns. I am 
really confused on how to show this dropdowns. Here's my bean class:

public class UserAccessBean implements java.io.Serializable {
 

List deptList  = new ArrayList();
List brokerList = new ArrayList();
List filters = new ArrayList();


 public List getFilters() {
 deptList.add(new LabelValueBean("1", "Department1"));
 deptList.add(new LabelValueBean("2", "Department2"));
 deptList.add(new LabelValueBean("3", "Department3"));


 brokerList.add(new LabelValueBean("broker1", "BrokerDepartment1"));
 brokerList.add(new LabelValueBean("broker2", "BrokerDepartment2"));
 brokerList.add(new LabelValueBean("broker3", "BrokerDepartment3"));
 
  filters.add(deptList);
  filters.add(brokerList);
  return filters;
 }


}

The 'filters' ArrayList can actually return 2 or more ArrayList. Like if there's 3 
ArrayLists, I would like an html output such as:

html:options question

[Gus Delgado]

I populate an html:option tag with a collection. I use the html:option 
to create a new user in my system and to edit a user in my system.


  


When doing an edit I want the html:option to be shown with the current 
accessType of the user I'm editing.

Example. the options are "Read-only", "Admin", and "Analyst" that's the 
order of the collection, when I edit a user that is Admin, I want the 
drop-down to show with the "Admin" being selected,

How can I accomplish this. Thanks in advanced.

html:select / html:options

[Christian Schlaefcke]

Hi Folks!

for several days I mess around with html:select and html:options.

I want to access a collection with names or numbers (just
java.lang.String). This collection is available in the session. For
testing I generated my own collection in the jsp

<%
 java.util.Collection list = new java.util.ArrayList();
 teilnehmerListe.add("name1");
 teilnehmerListe.add("name2");
 teilnehmerListe.add("name3");
 session.setAttribute("myList", list);
%>
 
  
   
  
  OK
 

When I run this I get an IllegalArgumentException: no name specified

I found out that both "select" and "options" have an argument "name" so I
added some dummies "test1" and "test2" just to have it and get (as
expected) another error: no bean found by that name "test1".

What am I doing wrong? Can someone point me to the right direction?

Thanx and Regards,

Chris

RE: html:options

[Sri Sankaran]

The first technique couples your presentation with your business logic more closely 
than does the latter.  So, my preference would be using the .

You can maintain the collection that makes up the options in the form bean for the 
page.  Initialization must be handled via the associated action class.

I want to display a dropdown list. The list items are "By First Name", "By Last Name", 
"By Date". I think I can do it by the following way:


 By First Name

Is there any disadvantages to use above approach compared with using

where should I set myArrayList? in init method of my servlet class, or in my action

html:options ordering

[Dennis Muhlestein]

I have a hashtable with key/value that get displayed by an html:options
tag.  

Works ok, but they are ordered in reverse order of the id.  That isn't
any performance problem, but it looks a little strange to the user.

For instance, what if you wanted the options in alphabetical order?  In
my case, I need them ordered by the key for each options.

Any Suggestions?
TIA

html:options bug?

[Lawlor, Frank]

The Struts Options tag seems to have problems accessing collections 
that are in some other object (e.g., your form).  The following dotted
notation should work (I thought) (roleList is an ArrayList):

   

   

or alternatively:

   

   

But both of these result in an error that a bean cannot be found in
roleList.
A workaround is to "cache" the list:

   
   

   

Is this a bug or expected behavior?

I've been using the html:options tag like following without any problems in
the past.
 







 
 
However, I recently get this weird javax.servlet.ServletException:
PropertyDescriptor: internal error
while merging PDs: type mismatch between read and write methods

 

When I change the code to the following and everything is working fine...Any
ideas?

 



<%

User[] users = (User[])session.getAttribute("allusers");

Date: Fri, 17 Aug 2001 10:14:38 -0700 




Hello,

I struggled with the options tag because I did not understand what it meant
by 'collection'.  I could not pass a collection along with a request because
I was at my index page.  In other words, nothing had been done yet.  

I instantiated the bean that had the collection and then used a  to make the collection visible to the options tag.

This is a sample define statement for a bean named Cost, with an ArrayList
(an array of costCentre objects) called costCentres.


I then reference it in my form via:

I hope this helps.

Re: HTML:OPTIONS

[Chris Heinemann]

I figured it out.  I need to have an intermediate "bean" to hold the values.
Thanks for you help.  I do think it would be very helpfull if an options tag
where passed only collection it call the toString method.  At least things
wouldn't blow up.  In a great many cases that would be the simplest thing.

Thank you,
Chris

I have a similar situation:

I'm trying to display the keys of an enumeration in a drop down list.

The keys are Integers and are stored in a Hashtable
>reports.put(new Integer(reportID), item);

The function getReportsKeys returns  reports.keys();

I have two questions:

1. Can html:options collection be used with an enumeration?

2. How can I display the list of keys in JSP?
I have this, what should go in ___WHAT_GOES_HERE???,
I tried intValue   //from the Integer class, but I get
"javax.servlet.ServletException: No getter method for property
reports.reportsKeys of bean com.gs.ed.sh.GLOBAL"

if there's no solution, would I have to create another class call reportID

MessageResource, html:options & i182

[Lars Bergström]

Part 1
On a jsp page I want to have a html:select of the type that has a
predefined
number of options, e.g. different sports. Now, I want to make use of
Struts
internalization where the differents locales text strings are retrieved
from
its locale properties file. 

If I read the text strings from the Message resource file one by one
then I
have to edit my java code when I find out that I want another sport in
my
html:select. In my case a new sport is added very seldomly. 

Is there a nice way of using struts tags like logic:iterate together
with
html:select or 
Can I in some nice looking way with the help of MessageResourceBundle
class
retrieve all text strings starting with sports.* ? 

Part 2

Have being doing some thinking and reading,

In chapter 13.4.3 (Struts in Action) I found text talking about exaktly
this.
Still, the "keys" array must be populated in some way. One alternative
is to
have a separate properties file that holds all the keys for different
sports.
Another alternative is to have a database table containing the keys. 

org.apache.scaffold.text.MessageUtils? Whereever did it go? Can't find
it!
Anyone? 

An aspect of this is how often you estimate that the information will be
edited by the end user. If the end user never or almost never add new
sports,
then saving the i18n strings in a Resource files would be alright.
However, if
the end user quite frequently changes the information, perhaps would it
then
be more convenient to store the information in a database since it can
be
viewed more a part of the application rather than a part of the delivery
of
the product. 

Best regards

Simple html:options question

Hi all,

I have an ArraList of strings that I want to show in a drop-down box. The 
same thing is both the label as well as the value. Can anybody tell me how I

collection attribute of  tag is used to set the name of a bean (in some

You need to put your Vector into page or request scope to use this tag:

also with the example you gave me should

   

shouldn't the value of collections be items, since that is the key you used.

Re: URGENT: html:options

[Nicolas De Loof]

create a scripting variable "agencyIds" and a page scope bean "agencyIds". This 
created vector is empty.

<%  agencyIds= MyUtils.getAgencyIds();   %>

chags the object referenced by the scripting variable, but not the page scoped bean.

You should use something like this, assuming populateAgencyIds(List) adds items to an 
existing List :

<% MyUtils.populateAgencyIds(agencyIds); %>

html:options maximum length?

[Matt Redman]

I have a an Array with a large list of names in it (up to about 1000+ or
more).
I need to display these names in a drop down list, but when The page loads
it
simply stops loading after about 837 lines.
 
The code I am using is:
 



 
Any ideas why it only displays a part of the Array and not the full thing?

html:options and javascript

[Neth]

Hello,

I have an existing application which i converted into struts,
however i'm having some problem with regards to option with javascript.
The picture of the user should be reflected whenever his/her user id is
selected from the drop down box.

Below is the working application:


function showimage()
{
if (!document.images)
return
document.images.pictures.src=document.mygallery.userId.options[document.mygallery.userId.selectedIndex].value;

}


 
   <% for (int i=0;i

   <%=LoginManager.getusers(i)%>
   <% } %>
 
 


 
   <% if(LoginManager.getNoUsers()!=0){
   init = "pix\\" + LoginManager.getusers(0) + ".jpg";
  }
   %>

 
 

Conversion into struts not working


function showimage(){
 if (!document.images)
 return
 
document.images.pictures.src=document.forms.userId.options[document.forms.userId.selectedIndex].value;
// error here
}

html:options encoded property

[Nathalie Foures]

Hi!

I wrote a JSP page with the following lines :
...

   

...

where name and url are the String attributes of a bean named Proxy. This
code displays a box, with a list of "names". When I select a name, this
returns the corresponding "url". The problem is that the url is written
with escaped characters, BUT displayed with unescaped characters.

For example, the bean Proxy has the following url linked with the name
"something" : "http://myhome/hello&action="doSomething"";.
But, the resulting html page looks like this :
...

   http://myhome/hello&action="doSomething"";>something
...

The " character is translated. As a result the option value becomes
"http://hello&action="; : it stops at the first ":" character and doesn't
take the whole url! doSomething is forgotten...

I looked for attributes like "filter" for the html:options tag, but I
didn't succeed...Has someone an idea to help me!

Thank you!

Nathalie

what i really need is to pass to the result action the value which represents the 
labels that contains the SectorCompany ArrayList, so, How i can build a select that 
shows labels but that also stores the id (longs representing registers in a RDBMS) to 
pass this id?


Thank everybody in advance.

ps. If someOne knows a subject in the mailing list which already solves this plese 
redirectme to it.

Re: html:options question

[Heather Buch]

I did something similar, with optionsCollection (which I like).

Here is my code:


 


for optionsCollection, my "property" is the name of my bean, and I think 
you have to pluralize it (example availablecourselabel --> 
availablecourselabels) to indicate that it's a collection. The "label" 
and "value" attributes just
refer to properties of my AvailableCourseLabel bean (get 
availableCourseconcatenated, and getAvailablecourseinstanceid). I hope 
this helps  a little.

Best,

Heather Buch

Just make sure "accessType" is set to whatever the value is for
"Admin" in the options. In other words the value fields in
accessTypeList should have "Admin", "Analyst", "Read-only" and
then accessType should also be one of those names as well. (Personally
I usually like to use ints for those values. So that accessType would
be an int value and in the accesTypeList you'd have corresponding
ints for the values and the label would be your String for the title
(Admin, Analyst, etc)). If that doesn't make sense let me know. I
typed this up very quickly:)

RE: html:select / html:options

[Kandi Potter]

I'm just learning here as well.but that is what worked for me.   I actually store 
the vectors in a CollectionForm with the two vectors as members.  I don't know if this 
was the most graceful way to handle the problem, but it worked for me.  I have 
something like this:

I used a CollectionForm for the same purpose as you would like to.  I have several 
drop-down selections so I just create a CollectionForm object for each, and populate 
the labels and values from my business object, which I'm sure you have done already.

also, for state management, the collectionForms are stored in a transaction to be 
re-used during the same session.  This way I can grab them for any action where I need 
the same drop-down list.   

public class CollectionForm   implements Serializable {
private Vector labels;
private Vector values;

...

public class IncidentForm extends ActionForm implements Serializable {
public Vector getUnsafeLabels(){
return CollectionForm.getLabels();

}

public Vector getUnsafeValues(){
return CollectionForm.getValues();
   
}
...

html:options with validate

[Sniadach, Tomasz]

hi , 
i have an ActionForm with countries in html:options , there are some
other fields, that i have to validate. So, when i submit and errors
occur, the field selected in countries is set to default. Is there a way
to mark the selected field? 
The other fields (text fields) are not cleared.

In my JSP i have something like this:




in the Form ;

public String getSelectedLand() {
return eb.getLand()[0]; 
}

public String[] getCountries() {
return eb.getCountries();
}

Thx for suggestions.

Hi Folks!

for several days I mess around with html:select and html:options.

I want to access a collection with names or numbers (just
java.lang.String). This collection is available in the session. For
testing I generated my own collection in the jsp

<%
 java.util.Collection list = new java.util.ArrayList();
 teilnehmerListe.add("name1");
 teilnehmerListe.add("name2");
 teilnehmerListe.add("name3");
 session.setAttribute("myList", list);
%>
 
  
   
  
  OK
 

When I run this I get an IllegalArgumentException: no name specified

I found out that both "select" and "options" have an argument "name" so I
added some dummies "test1" and "test2" just to have it and get (as
expected) another error: no bean found by that name "test1".

What am I doing wrong? Can someone point me to the right direction?

Thanx and Regards,

Chris

Hi,

I believe you need to read the following link 
http://www.jajakarta.org/struts/struts1.1/documentation/ja/target/userGuide/
printer/struts-html.html#options

This should give you an idea of what the attributes of html:options are.
Collection should be a set of java beans. Rules are clearly provided in the
above link.

I can give you an example using

session.setAttribute("myList", list);
session.setAttribute("myList",list.toArray());

for some reason you need to cast to list to an array.

Re: html:options ordering

[Danny Mui]

Hash Tables don't guarantee order when you pull them out enmasse. 
probably best bet is to store it in a list and sort accordingly 
(Collections.sort).

I would look into the Commons Collections library.  It appears you could use
either the DoubleOrderedMap or the SequencedHashMap.  I haven't personally
used either of these.

if you're using jdk1.4, try java.util.LinkedHashMap which preserves

Thanks for the comments.  Seems to make more sense not to have

Re: html:options bug?

[Arron Bates]

The collection attribute needs the bean reference only. The dot notation 
is for your property. Because the collection isn't the bean itself 
you'll have to use a define tag or something to make a bean reference 
directly to your collection, then use that reference in your collection 
attribute.

For your second example... The collection attribute is overriding, and 
ignores the name attribute. It's meant to be the direct link to a bean 
reference that itself is a collection.

Arron.

html:options list source question

[Craig Berry]

After much googling and head-scratching, I finally have an html:options tag working on 
a jsp.  The problem is that I don't know why one component of the solution is needed, 
and I was hoping someone can explain it to me.
 
My ActionForm subclass, EditDeForm, has a pair of methods to provide the option list 
as part of the form bean:

public Collection getNumFmtOptions() {
  ArrayList list = new ArrayList();
  list.add(new LabelValueBean("None", "0"));
  list.add(new LabelValueBean("Comma separated", "1"));
  list.add(new LabelValueBean("Currency", "2"));
  return list;
}
 
public void setNumFmtOptions(Collection options) {
  // No op, here to satisfy bean-ness.
}

The jsp page contains an html:form section linked via action mapping to the EditDeForm 
type.  In it, there is a select/options section that looks like this:


  
 

I had thought that this would be enough to make it work.  The html:options is in the 
context of an html:form that knows about the current form bean, and the form bean has 
a property numFmtOptions that contains what is needed to populate the options list.  
But when I tried just this, I got a "cannot find bean" error on numFmtOptions.
 
The googling mentioned above finally revealed that I had to add this at the top of my 
jsp:



My question is:  Why?  What is this additional definition for?  What information does 
it supply that isn't already available to html:options inside the html:form context?
 
I'm happy that I have my code working, but I'd be even happier if I knew why it's 
working. :)

You could use a single key with some sort of delimter:

and parse the key to create your options.

Subject: MessageResource, html:options & i182


Part 1
On a jsp page I want to have a html:select of the type that has a
predefined
number of options, e.g. different sports. Now, I want to make use of
Struts
internalization where the differents locales text strings are retrieved
from
its locale properties file. 

If I read the text strings from the Message resource file one by one
then I
have to edit my java code when I find out that I want another sport in
my
html:select. In my case a new sport is added very seldomly. 

Is there a nice way of using struts tags like logic:iterate together
with
html:select or 
Can I in some nice looking way with the help of MessageResourceBundle
class
retrieve all text strings starting with sports.* ? 

Part 2

Have being doing some thinking and reading,

In chapter 13.4.3 (Struts in Action) I found text talking about exaktly
this.
Still, the "keys" array must be populated in some way. One alternative
is to
have a separate properties file that holds all the keys for different
sports.
Another alternative is to have a database table containing the keys. 

org.apache.scaffold.text.MessageUtils? Whereever did it go? Can't find
it!
Anyone? 

An aspect of this is how often you estimate that the information will be
edited by the end user. If the end user never or almost never add new
sports,
then saving the i18n strings in a Resource files would be alright.
However, if
the end user quite frequently changes the information, perhaps would it
then
be more convenient to store the information in a database since it can
be
viewed more a part of the application rather than a part of the delivery
of
the product.

Re: html:options maximum length?

[Richard Yee]

I think you should re-think your UI design. Besides being very slow, the 
select box will be very annoying and difficult for the end user to use. You 
should try and narrow down the users choices before they get to the select 
box page so that you only need to show a few dozen options at most.

Richard

html:options == null after inputForward

[Kersten]

Hi,
I have an ActionForm for my JSP with contains one String for the 
"html:select", one String-Array for the options property and one 
String-Array for the optionslabel.
There are getter and setter - Methods for all of these variables.

...
private String pwGruppe_ausgewaehlt = null;
private String pwGruppeID[] = null;
private String pwGruppeLabel[] = null;
...
//I don't want to show the whole getter and setter here...

In my JSP I'm using the following to show a popup-menu:





To show this in my JSP is no problem. But if the ActionForm detect a 
problem (in the validate - methode) in the JSP, it tries to redirect 
to the JSP with the error and the old data from the JSP. But struts seems 
not to be able to catch the data from
the "options". While loading the JSP I get an error that the pwGruppeID is 
null. Is there a way to solve this problem?

RE: html:options encoded property

Correct me if I'm wrong, but aren't the "e; entries unnecessary?
Couldn't you just remove them?

Subject: html:options encoded property


Hi!

I wrote a JSP page with the following lines :
...

   

...

where name and url are the String attributes of a bean named Proxy. This
code displays a box, with a list of "names". When I select a name, this
returns the corresponding "url". The problem is that the url is written
with escaped characters, BUT displayed with unescaped characters.

For example, the bean Proxy has the following url linked with the name
"something" : "http://myhome/hello&action="doSomething"";.
But, the resulting html page looks like this :
...

   http://myhome/hello&action="doSomething"";>something
...

The " character is translated. As a result the option value becomes
"http://hello&action="; : it stops at the first ":" character and doesn't
take the whole url! doSomething is forgotten...

I looked for attributes like "filter" for the html:options tag, but I
didn't succeed...Has someone an idea to help me!

Thank you!

Nathalie

Ye olde html:options tag?

[Michael P]

I apologize for this basic question, but I'm new to struts and Java web
programming in general, and I really can't get the  tag to
work...

The error I'm getting, specifically, is:
  javax.servlet.jsp.JspException: No getter method available for property
email for bean under name users

My JSP defines a collection like this:
  

Then tries to use it like this:
  

  

My understanding of this is that it will call getUsers() on the
adminLoginForm bean to get a Collection, and then on each item within the
collection, will call getEmail() to retrieve the option property and
label.

Do I need to define a bean somewhere (in some XML file?) for the user
objects contained within the collection or something?  The collection
contains UserView objects that /do/, in fact, have a getEmail() method, so
I can't figure out why this won't work.

I have defined a form-bean for the login form:
  

  

Thanks for any help you can offer...

You can use the LabelValueBean class for that, see www.husted.com for

html:select and html:options example?

[Stephan Niedermeier]

Hello,

who can give me an example, how to use the html:select in conjunction with
html:options? I had already defined an ActionForm and JSP like follows. The
listing of the option-Elements works fine but not the "reshowing" of the
selected elements of the list, because after I have clicked the submit
button I've got an IllegalArgumentException (BeanUtils.populate):

java.lang.IllegalArgumentException: argument type mismatch

My FormBean looks like this:
{...}
public final class RoleEditForm extends ActionForm {
{...}public void setAllUsers(ArrayList allUsers)
 this.allUsers = allUsers;}public ArrayList getAllUsers()
 return this.allUsers;}
{...}}
The allUsers list contains user objects. The user objects have the accessor
methods getId(), getName().
My JSP looks like this:





After clicking the submit button I've got the Exception. That's wrong?

Thank you very much!

Stephan

Re: html:options and html:select

[Claire Wall]

you can do the following:



">




'property' of the select box should be the name of the property in your
FormBean that you wish to store the selected value in.
You then iterate through the list in your form by using the 
tag. For every object in your list an  tag is written, where the
value is the property 'id' of the current CProduct and the name displayed in
the select box is the name of this CProduc object. This may not work as it
stands due to using an Integer object - i'm not certain that you can set the
value of a select box option to an Integer object. You'd have to try it and
see, and perhaps somebody can clarify this further, but I've never tried
this myself.

Re: Help with html:options

[Matt Veitas]

Change the attribute "name"  to "collection" and it should work.

This tag operates in one of two major modes, depending on whether or not 
the |collection| attribute is specified. If the |collection| attribute 
is included, the following rules apply:

* The *collection* attribute is interpreted as the name of a JSP
  bean, in some scope, that itself represents a collection of
  individual beans, one per option value to be rendered.
* The *property* attribute is interpreted as the name of a property
  of the individual beans included in the collection, and is used to
  retrieve the value that will be returned to the server if this
  option is selected.
* The *labelProperty* attribute is interpreted as the name of a
  property of the individual beans included in the collection, and
  is used to retrieve the label that will be displayed to the user
  for this option. If the |labelProperty| attribute is not
  specified, the property named by the |property| attribute will be
  used to select both the value returned to the server and the label
  displayed to the user for this option.

html:select and html:options tags

[Viet Kevin]

Hello all

My question is about the struts html:select and html:options tags

public class xxxForm extends ActionForm 
{
private Person choosed;
private Collection persons;


public get...
// accessors for this attributes are defined but I do not display
// them
}

When creating the form I set the choosed properties to firs instance in the persons 
list
xxxForm.setChoosed(xxxForm.getPersons.iterator.next());

Then I want to display that list in a html page for selecting a person in that list.
The html select must list all the persons AND the chooseen one must be displayed first 
(setting the html-attibute selected="selected" for the choosen one)

The other problem is that I want to use an index (an int that index the instances in 
the list) as the value
of the html option tag (not the name of the person)

so the html produced must be something like : 

 John  
 Henri 
 Max 


I play a lot of time trying to obtain this result with the struts tags 
but never figured out how to do it

Please tell me if it is possible to do or propose me an other solution
but I must have an index in my list so the value in the option tag must 
be an int


And the last question is I can't see what the attribute named tabindex in the 
html:select
tag is used for?

Thx in advance

Re: CachedRowSet for html:options

[Adam Hardy]

You mean you're displaying a list in a table or you are displaying a select drop-down 
box?

The html:options tag works great with forms, it'll initialize the select box to what's 
in the form object, and it'll display appropriate labels and set up the appropriate 
values on each option.

You can quite easily use the CachedRowSet.toCollection(column) to return any column of 
the rowset as a collection. Instead of putting the whole rowset in the session, you'll 
have to put a collection for the values and a collection for the labels. A few more 
lines of code, yes, but not exactly difficult.

If your lists are just lists and not select boxes (it's not clear from your message), 
use a logic:iterate tag.

RE: CachedRowSet for html:options

[Sunder R Somasundaram]

Thanks for your reply; it is a select box with single or multiple
options. Do I have to put in both the values and the labels even if both
are the same?

http://jakarta.apache.org/struts/doc-1.0.2/struts-html.html#options

* If the labelProperty attribute is not specified, the property named by the 
property attribute will be used to select both the value returned to the server and 
the label displayed to the user for this option.

html:options problem with labelProperty

[Allen Walker]

I have the following:

[html:select property="merchandiseCategory"]
[html:options property="merchandiseCategoryCodes" 
labelProperty="merchandiseCategoryDescriptions"/]
[/html:select]

Now when I take out the labelProperty attribute, all works. When the 
labelProperty attribute is in, I get:

java.lang.NullPointerException at 
org.apache.struts.taglib.html.OptionsTag.doEndTag(OptionsTag.java:296) at 
_jsp._cbmsi._admin._editbookrecord__jsp._jspService(D:\work\resin-1.2.7\webapps\cbmsi\admin\editbookrecord.jsp:101)
 



This worked fine until I moved to Struts 1.0.2. There is nothing wrong with 
my formbean, it contains the "merchandiseCategoryDescriptions" getter on 
the associated form bean.

Thanks for any help.

html:options Iterator Creation error -

[Sunder]

Hi, 
I am trying to implement the html:options tag in one of our
applications,

I have a form bean with the following attributes,

private Collection securityOptions = null;
private String security = "Default";

In my action class, I populate the collection with 

PersonalForm perform = (PersonalForm) form;
Collection list = (Collection) new ArrayList();
for(int i = 0; i<10; i++)
{
list.add(new LabelValueBean("Default","Value"));
}
perform.setSecurityOptions(list);

and finally in my jsp, I try to display the collection using
html:options tag as follows

 
 
  


I get the following error when I try to view the page
