In this case mine is

Service sets the values and they are read from the page using

The  needs to be provided with the property it's associated to,
the one on your form bean that will hold the actual value selected.

  

"mySelectValue" should be a property on your form bean.

Re: Using optionsCollection - LabelValueBean

[Timo Tjäder]

Hi,

Thanks Hubert, the problem was on the html page.

1. I forgot to add second form tag to handle page linking system on footer.
2. Also as you mentioned all the parameters must be match with the form beans I am 
posting. 

After making those changes the combox box was redered nicely on same lone
with navigation numbers.

1 2 3 4 5 next COMBOBOX v

I have one rule when writing jsp pages and it is "no scriplets anymore".
The Struts handles everything nicely if some time is offered in designing 
the beans and linking system.

In this case mine is

WEB->FORM->ACTION->SERVICE->BEAN
WEB<-FORM<-ACTION<-SERVICE<-BEAN

Service sets the values and they are read from the page using
struts tags (equal/iterate/present). The totalNumOfPagesCollection 
comes actually from BEAN.

Thanks,

Timo

Re: Using optionsCollection - LabelValueBean

[Hubert Rabago]

The  needs to be provided with the property it's associated to,
the one on your form bean that will hold the actual value selected.





"mySelectValue" should be a property on your form bean.

Hubert

Using optionsCollection - LabelValueBean

[Timo Tjäder]

Hi,

I have problems with optionsCollection, when used with

This part should display a combo box with options, but
it just does not work. It does not display anything.

Html code is as follows:





I have checked using struts "bean:write" the contents of 
the object. Bean write claims that totalNumOfPages really 
contains LabelValueBean-objects (14 peaces).
LabelValueBean[1, 1], LabelValueBean[2, 2], LabelValueBean[3, 3],

So, does anyone know how to reference to this object correctly.
Current solution does not diaplay anything to the screen.

Thanks,

So what I'd like to do is display a selection list of
all availabele pages from which user choose one and press
a goTo page button. This is quite common web control in

Actually, he's right. :)  My advice only applies if you have
name="myForm" in your  tag.  If not, Struts will pass a null
form into the execute method.  It may have digested struts-config.xml,
but without the name attribute in the form tag, it will not have
actually instantiated one for you.

I don't use any pre-processing Actions.  Mine are all
LookupDispatchAction, so the form is always there, although if it comes
in with no parameter, the unspecified method will pre-fill the form from
the database.

Re: rePost: How to set the selected value in an select rendered by optionsCollection

[Niall Pemberton]

Its the name/property specified on the  tag that causes
OptionsCollection to set "selected" - in your case the select tag needs to
look at he country property of the customer bean - if optionsCollection
finds a value that matches that, it will set selected.

rePost: How to set the selected value in an select rendered by optionsCollection

[Frank Schaare]

Hi all,

i´m reposting my problem trying to be a little bit more specific. This 
problem is very important for me, though i made another 'book like' 
example to show where i am.

There are three beans playing in my theatre:
1. the CommonValuesBean which stores frequently asked data for my JSP 
HTMLForms
2. the CustomerBean which is an buisiness objekt representing a customer
3. the DynaForm which stores data coming from my JSP HTMLForms.

First of all, the CommonValuesBean is initialised. Therefore, i´ve got 
the sessionListener that puts data in it, anytime a new session is creatd:

public void sessionCreated(HttpSessionEvent event) {
	CommonValuesBean commonValuesBean = new CommonValuesBean(); // create 
new bean instance
	HashMap countries = new HashMap(); // Create new map
	countries.put("countryCode1","country1")
	countries.put("countryCode2","country2")
	countries.put("countryCode3","country3")
	
	countries.setCountries(countries); // Our example map is now stored
	
	HttpSession session = event.getSession();
	session.setAttribute("commonValuesBean",CommonValuesBean);
}

Now we begin to deal with the customers. There is listCustomers Action 
that shows all of the customers. You can klick one to
get more detailed information using the customersDetailsAction:

public class customersDetailsAction extends Action
{
private Customer customer = new Customer();
	public ActionForward execute(ActionMapping mapping,ActionForm 
form,HttpServletRequest req,HttpServletResponse res)
		throws IOException, ServletException
	{
	customer.setFirstName("Frank");
	customer.setLastName("Schaare");
	customer.setCountry("country2");

	req.setAttribute("customer",customer); // storing customer in request
	
	return mapping.findForward("customerShowDetails"); // mapped to 
customerShowDetails.jsp
	}
}

The customerShowDetails.jsp looks like this:


.
. tons of markup
.

	

.
. again: tons of markup
.



The problem is, that the  renders a select like 
this:


country1
country2
country3

i desperately NEED to render the select like this:


country1
country2   
country3

because my customer lives in country2 !

Is there any way to tell Struts to do this ?

Re: How to set the selected value in an select rendered by optionsCollection

[Frank Schaare]

Hi Hubert,

This would only be true if the action that was called specified that form in
its mapping.  If this is a preprocessing action (that's being called to
provide an HTML form with data to show), and there's no "name" attribute to
tie a form to it, Struts will not create/populate a form (because it wouldn't
know what form to create).  
Sorry, but i guess you are wrong.

The declared formBeans are digested during ActionServlets.init().

If you have a tool that is able to visualize your Java Objects like the 
'variables' view in Eclipse, you will see the following right after 
applications startup, when setting a breakpoint in any action:

mapping/moduleConfig/formBeans which is a HashMap. All your declared 
beans are right there.

Does anyone know the right way to access this HashMap ?

Anyway, we became very far away from my optionsCollection problem. I´ll 
try to repost it trying to be a little more specific.

This would only be true if the action that was called specified that form in
its mapping.  If this is a preprocessing action (that's being called to
provide an HTML form with data to show), and there's no "name" attribute to
tie a form to it, Struts will not create/populate a form (because it wouldn't
know what form to create).  

You can make the form available to this action if you specify the form you
want in the "name" attribute in this action's mapping.  However, this would
not be good practice since the preprocessing action could itself require a
form of a different type.

No.  The execute method is in the Action, not the ActionForm.

> Shall i cast my business object 'sb' ? That would look like this:
> DynaActionForm dSB = (DynaActionForm) sb

You just said 'sb' is an ActionForm, so it cannot (well, should not,)
also be a business object.

We need to know about your Action class.  That's the one with the
execute method, which has a signature like this:

public ActionForward execute( ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response )

Inside that method is where you cast 'form' to whatever type of form you
have.  Then you'll have access to the 'set' methods of your particular
type of form bean.

If I'm still not understanding properly, please try again to explain
what you need.

Re: How to set the selected value in an select rendered by optionsCollection

[Frank Schaare]

Hi Wendy,
thx for your reply, but there are some questions left:
this is where i am: there is my business object 'sb' and the upcoming 
DynaActionForm. sb extends ActionForm, there should be sb.execute().

Nope.  It goes request->form creation->action.  You are being passed the form in the signature of ActionForm.execute(), all you have to do is cast it to the right type:

  DynaActionForm dForm = (DynaActionForm) form;
Shall i cast my business object 'sb' ? That would look like this:
DynaActionForm dSB = (DynaActionForm) sb
Or shall i look for the DynaActionForm in sb.execute() which will look 
like this:
sb.execute()
{
//there must be a way to access Struts DynaForms
.
DynaActionForm dSB = (DynaActionForm) form
}
How do i get the form Objekt ?

I debugged deep into Struts sources, found a 'mapping' Object with a 
'formBeans' Vector but no way to access this mapping.
Do you have a suggestion ?

Nope.  It goes request->form creation->action.  You are being passed the form in the 
signature of ActionForm.execute(), all you have to do is cast it to the right type:

  DynaActionForm dForm = (DynaActionForm) form;

Now set whatever properties of dForm you need to, then forward to the JSP.

Not recommended.  They might be the same *now* but if your business object changes in 
the future, you don't want that to be tied so closely to your webapp.  Since you're 
using dyanamic forms, it's not THAT much trouble to maintain a business object plus 
some lines of XML.  Or you can use a tool to generate all the get/set methods for a 
regular ActionForm.

Re: How to set the selected value in an select rendered by optionsCollection

[[EMAIL PROTECTED]]

Hi Nagiel,

if (sb.getTitle().equals("Mr."))
formularBean.setTestSelect(sb.getTitle())
in your preprocessing action class to set the value of "testSelect", which will automatically add the SELECTED attribute on the option tag?
because of the fact, that i´ve got no access to this bean in my 
preprocessing action. testSelect is a member of the upcoming 
DynaActionValidatorForm with is initiatet during the  tag of 
my JSP.

You are right the sbBean and the DynaActionValidatorForm have exactly 
the same members which seems to be a big design failure in my 
application. I should get rid of the sbBean and initiate the 
DynaActionValidatorForm earlier in my preprocessing action.

But how ??? Does anyone have an example how to retrieve a 
DynaActionValidatorForm from the mapping ?

And, if i use the DynaActionValidatorForm earlier in my preprocessing 
action, store it in requestScope, does the  Tag take notice 
of it, or simply 'overrides' it ?

It is my first Struts app and this is quit complex for me, hope Nagiel 
or someone else will help.

Thank you.

I'm not sure if I fully understand, but why not use:

if (sb.getTitle().equals("Mr."))
formularBean.setTestSelect(sb.getTitle())

in your preprocessing action class to set the value of "testSelect", which will 
automatically add the SELECTED attribute on the option tag?

The FormBean contains a domestic_Foreign property (a string), and a

Hallo,

i´ve made a select from an optionsCollection Tag. The values are read 
from a hashmap like
value1 = one
value2 = two
value3 = three

Now i´d like to set a default value for this select, which is NOT PART

like this:
please select...
one
two
three

is there any way to achieve this result in struts ?

I have two problems that I think are related, so I'm including them both
in this email.  I'm using Struts 1.1.

Problem #1:

I am trying to use a mapped property on an html:checkbox, and it does
not appear to be setting the value of the property to true if the
checkbox is checked and submitted.  This is the line in my JSP:



In the reset method I set all Boolean objects in the map to
Boolean.FALSE as indicated in the html taglib documentation.  It works
fine if I use a "scalar" field with a boolean primitive like the
following:

protected boolean booleanValue = false;
public void setBooleanValue(boolean value)...
public boolean getBooleanValue()...

and



I'm wondering if there is a problem where the mapped property is not
being set properly (since checkbox is probably trying to set a boolean
value instead of Boolean).  Has anyone else encountered this before?

Problem #2

I am trying to use another mapped property in the same ActionForm
implementation on an html:optionsCollection.  

  
  
  

I initialize the dbList's value in the Map and the optionsCollection
loads properly in the browser.  However, on submission I only get the
first value if multiple values of the list are submitted in the Map for
the selectedDb key.  I suspect there might be a problem setting the
String array in the Map for some reason.

I also tried this with a "scalar" field and it worked just fine:

protected String[] selectedDbList = null;

public String[] getSelectedDbList() {
return (this.dbList);
}
public void setSelectedDbList(String[] selectedDbList) {
this.selectedDbList = selectedDbList;
}

and 





I get the impression that both these problems are bugs, and if so, I'd
be interested in looking into how to fix them.  So, if anyone has a idea
where I should look first it would be very helpful.  Or, if they're not
bugs, I'd really appreciate any help you can offer.

PLEASE IGNORE THIS PROBLEM. NOW RESOLVED.


The optionsCollection tag does work properly. I was using it properly. 
Just had a build issue that caused the strange behaviour.

Thanks and sorry

All,

I am having a problem using the optionsCollection tag.

I get this error:

private String[] reasonsForTicketIssue;

public List getReasonsForTicketIssueOptions() {

Having traced through the code I find that the correct bean is looked up 
successfully (i.e. the form bean) but that there is no property for the 
'reasonsForTicketIssueOptions' property in the property descriptors that 
are used by PropertyUtils.

Am I correctly using the optionsCollection tag?

Is my 'public List getReasonsForTicketIssueOptions()' method correct?

Does any one have an example of using this tag where the form bean returns 

the collection of LabelValueBeans?

Surely what I am doing is standard hence the existence of the 
optionsCollection tag.

Thanks for any help.

Hi there. 

Is there any way to use resource bunlde from within

And by the way, is there any equivalent for struts

Re: Wanted best practice for i18n'd optionsCollection

If we populate the items in the drop down menu collection, then I actually
have to do the same thing again and again for every collection instead of
leaving it to the framework to do so. The programmer has to figure out what
specific collection he would need in the jsp and populate them in "Action"

I haven't had a need to solve any i18n issues, but since you can get an
access to the user's locale in your Action form, wouldn't it be simpler
to just pass this locale into your business tier so you could populate a
collection the correct i18n data? The JSPs and tags wouldn't know the
difference or even care whether the collection was in English, German,
etc.

Re: Wanted best practice for i18n'd optionsCollection

[Christopher Cheng]

I posted a similar question long time ago in this list. -> Nobody cares.

So I developed my own custom tag to do it. What I did is populating the
collection with locale keys in the label of the LabelValueBean and then get
the exact message from the property file. If you want it, I can send you a
copy of it.

Wanted best practice for i18n'd optionsCollection

[Bob . Coss]

Hi all,

I've successfully used the applications.properties method of isolating my
messages, prompts etc. so I can use different locales in my struts pages.  I
have some static select fields and I'm wondering what would be the best way
to use something like the optionsCollection to work with different locales.

As near as I can tell I might:

- Create a custom tag that builds the collection for a particular locale and
sticks it into the Application Context if it is not already there.  Then put
a reference in my page context for the "generalized" collection property to
reference.
- Then use OptionsCollection to display the collection of select options.

I've not been able to figure out the best way to do this since there doesn't
seem to be locale information for the optionsCollection tag.

Any suggestions would be gratefully appreciated!

Thanks in advance,

Bob

Re: Help with optionsCollection error

[Peng Tuck Kwok]

Ok here goes :
The original method for the attribute recipients was :
public void setRecipients(Vector input)
That caused the errors of the type mismatch ,
So I tried changing it to take to array of strings, like this
	public void setRecipients(String [] one, String [] two)
It doesn't complain about anything, but it doesn't pass any values to it 
as I have tried putting in a few println statements in there.

Another question Ian, since I changed it, what values would be passed

in there but apparently the output does not come out.

Hi Ian, your tip worked like a charm and I substituted it with the
setRecipient(String key, String value) method. Hmm now I need to see
what exactly I put in there.
Ian ever thought of adding this as a faq in Struts ?

public void setValues(String key, String value)
for instance.  The introspection done by Struts can't tell the
difference so
you get an error thrown by BeanUtils.populate where it tries to call
setValues(String key, String value) with only one value.
There has been a fair amount of debate about this recently, but if you
have
overloaded setter methods, comment all but the one that suits the type
of


value you're really using, and see if it works.

I had to go from having
public void setIds(String ids[])
and
public void setIds(int i; String ids[])
to having

public void setIds(String ids[])
and
public void setId(int i; String ids[])
see the difference?  The "s" is gone in the case of the indexed

See if that applies to your situation.

Re: Help with optionsCollection error

[Peng Tuck Kwok]

Another question Ian, since I changed it, what values would be passed 
into the two inputs ? I tried doing a System.out.println to see what's 
in there but apparently the output does not come out.

Hi Ian, your tip worked like a charm and I substituted it with the
setRecipient(String key, String value) method. Hmm now I need to see
what exactly I put in there.
Ian ever thought of adding this as a faq in Struts ?

You say :

Which bean would that be? The form bean or the collections of beans that

and overloaded the String[] or Collection setter method.

Help with optionsCollection error

[Peng Tuck Kwok]

I've sucessfully managed to display a multiple options in 
but when I click on submit I get errors.
One condition is when I don't click on any of the options , this error
would be failed to obtain specified collection when ever I try to access
the bean attribute that contains the values. The bean attribute is a
vector FYI.
The second condition is when I click on one or more of the options and
click submit I get a beanutils.populate error, type mismatch.
 

   
The form name is compose and recipients is a vector.

Does anyone have a idea where I'm going wrong?

Rick,


Task Code Type
  
  Internal
Client1
Client2
Development

It appears that I have the taskCodeType defined as char(15) in my
database --- that's why the value
is D(14 spaces)

I need to either make the values column char(15) or switch taskCodeType to
be a varchar.

Thanks for your help!

You're not debugging JSP pages, you're debugging pure java code.  You just set

I'm positive this works as I had the formbean working with html:text tags to

When I change from html:text to html:select with html:optionsCollection the

RE: Re: OptionsCollection

[shirishchandra . sakhare]

Hi,
There are many ways of doing this.So first is as the collection is being 
displayed on screen,make it an attribute of form and popolate it in action on 
form.So in jsp u will access like a form attribute.

But the problem with this approach is If u get an error and forward back the 
user to same jsp, u loose the collection data as u are directly going to the 
screen.So the solution could be have a generic action which will be called in 
case of errors and the action will populate form with list before forwarding it 
to same jsp.

Else U can have lazy in itialising forms.i.e forms getList emthod itself will 
call service to get data if list is null.And then in this case ,u can just use 
an epty action class which does nothing but forwarsd to "success" which is the 
origicnal jsp.But this action will be mapped with the Original actions form so 
that the form will use its auto population mechanism to get the list..But i 
dont like this approach ..just not a good design i think.But very conveninent.


Hope this helps,
Regards,
Shirish

Okay... But a drop down menu is screen data.

And a list of companies is something that will be used more than once.

So I have a normal class in my model layer

ListCompanies

In my UserAction

(ListCompanies).getCompanies();

But this Action's primary job is to return a list of users (which it does).

As the list is screen data i should be defining this in my form bean? This
is something thats being confusing me for weeks. If i've a bunch of
collections how can i make them available to iterate tags and select menus,
without using useBean (sorry silly design constraint, but beyond my
control).

Hopefully I'm just being silly, i could really do with some pointers as
where i'm missing the point.

Re: OptionsCollection

[V. Cekvenich]

Confused as to what your confusion is.

Are you confused that you see one thing and display another (which I get 
a lot from my students?).

There are 2 things going on, a client/browser side join not a db/server 
side join.
Example, you have a formBean with dept "101" a numeric field. You unit 
test this and CRUD. This is your Form Bean!!
Once you get that, then:
Now you want to display "Marketing" as a drop down instead of 101. So 
101-Marketing, 102-Sales, etc. You care a collection, yet another thing 
you put in scope.
The client side, using select and optionCollection tag displays current 
dept., and a choice of other depts.
So a user sees "Marketing" drop down, which comes from the name part of 
collection. But the current value is in the formbean.

Okay... But a drop down menu is screen data.

And a list of companies is something that will be used more than once.

So I have a normal class in my model layer

ListCompanies

In my UserAction

(ListCompanies).getCompanies();

But this Action's primary job is to return a list of users (which it does).

As the list is screen data i should be defining this in my form bean? This
is something thats being confusing me for weeks. If i've a bunch of
collections how can i make them available to iterate tags and select menus,
without using useBean (sorry silly design constraint, but beyond my
control).

Hopefully I'm just being silly, i could really do with some pointers as
where i'm missing the point.

You can either use attribute collection="users" for options tag if you store
in request
or you can use   name="formName" property="myList"   if you have
a getMyList() method for the form(You have to fill call formName.setMyList()

I've a number of collections already defined that end up being passed to my

Users in this case is a map defined in my business logic class that does db
queries.

users = (ListUsers).getUsers();

request.setAttribute("users",users);


I itertate through this collection using iterate. But now i want to use this

Should I be thinking about making my collection available to my FormBean i.e

optionsCollection error "Failed to obtain specified collection"after unsuccessful validate()

[adam kramer]

I'm using the Struts nightly build from nov. 13.

Initially I populate an ArrayList in a Validator form in an Action with
authentication types for a login screen.

In the jsp page, the authentication types are displayed with an
optionsCollection tag:





These are displayed successfully when the screen is diasplayed.
When I submit and purposefully leave out a required field (like username)
from the login form and submit, the screen should redisplay with
appropriate messages (it does without the optoinsCollection and select
tags). It doesn't. I get the message:

javax.servlet.jsp.JspException: Failed to obtain specified collection
at 
org.apache.struts.taglib.html.OptionsCollectionTag.doStartTag(OptionsCollectionTag.java:233)

So where is the collection going? It is in the form instantiation because
I 'set' it in the form in the initial action. Does the form reset() and
get rid of every attribute, including the array list?

Any help is appreciated.

Thanks,
Adam K.

p.s. I got the same problem with putting the Array List in the request
object after an unsuccessful validation.

RE: Get better performance with optionsCollection

[Jacob Hookom]

Try JSTL and see if that helps any.

Going on the caching idea, use  to write the output of the
iteration to an application scope variable, and only execute that bit
with a conditional if options not in application scope.

That way, you store the resulting html code in the application without
needing to regenerate it on every request.

Jake

Re: Get better performance with optionsCollection

[Cliff Rowley]

Alternatively, sometimes it may be more efficient both in terms of
performance and user interaction to think about how you present your
users with data, and how you receive interaction.  A very long drop-down
list may be (and often is) cumbersome.

Some points to think about:

- Is the list of items in this list likely to grow?  If so, is the
drop-down list approach still going to be acceptable when you have 200
or 300, 400, ... items?

- Is the list of items going to be used frequently by a user?  If so,
then any 'slight' annoyance will be amplified as time progresses (don't
assume a user will 'get used to it' - while it may be true in some
cases)

Can you present the data in another way?  For example, I recently took
over the development of a half finished ColdFusion based booking system
(which, incidentally I scrapped and built from scratch using Struts) and
the previous inhabitant had used drop-down lists pretty much everywhere
to make selections.  In one particular instance, when creating a
reservation using the system, the user was presented with a drop-down
list containing the names of all the customers in the database - which
is fine while there are only 50 customers there - but with new customers
being added daily, this is obviously not a long term solution.

To overcome this, I provide the user with a means to select a customer
by clicking a button which takes them to a customer selection screen. 
>From that screen they can view a paged list, or type a search term into
a text box.  When a customer is selected they are returned to the
reservations screen to continue creating a new reservation.  This
solution is not only future proof, but it is also much more user
friendly.  OK, so it's a couple more mouse clicks - but far less
irritating and cumbersome than scrolling up and down a lengthy drop-down
list - and also more featured.  (Incidentally the customer selection
process is also entirely detached from the reservation creation process,
and used in several places in the booking system - mmm reuse).

Obviously I am not suggesting you implement the exact same system - it
is just an example.  Usually, unless I have made a glaringly obvious
mistake, I take another look at my solution when I come across
performance problems - and quite often the result is a better interface.

I hope that made sense, it's been a long night and I don't feel
particularly articulate today.

RE: Get better performance with optionsCollection

[Joe Latty]

Not exactly sure if this will help performance but I am using the
org.apache.struts.util.LabelValueBean and the optionsCollection. Works a
treat, one other thing is maybe cacheing your "landliste" if this is
possible.

Hi!

I use a select-tag im my JSP. But now a have a performance problem, because

can the optionscollection tag use an array?

[Bill Milbratz]

Hi,

I'm looking over the documentation for the new  tag
and wanted to clarify a detail:

Can the 'collection of objects' (identified by the 'property' attribute)  be
an array of objects? Or must it be a java.util.Collection?

This is an issue because use of arrays would cut down a bit on our object
creation.

I know  can use an array, but I didn't want to make
assumptions about  .

thanks,

bill m

Bad release of tag html:optionsCollection

   Summary: Bad release of tag html:optionsCollection
   Product: Struts
   Version: 1.1 Beta 1
  Platform: All
   URL: http://www.mail-archive.com/struts-
user%40jakarta.apache.org/msg26926.html
OS/Version: All
Status: NEW
  Severity: Normal
  Priority: Other
 Component: Custom Tags
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]


The use of the optionsCollection tag with Weblogic produces errors.
The problem should be in the release method.

OptionsCollectionTag is initialized with :

protected String label = "label";
protected String name = Constants.BEAN_KEY;
protected String property = null;
private String style = null;
private String styleClass = null;
protected String value = "value";

but the release method defines :

label = null;
name = null;
property = null;
style = null;
styleClass = null;
value = null;

so label, name and value don't have their default values.

Hmmm, I guess this is something that needs to be fixed. :-) I think I 
missed this in the code...

> Do you used the name and value attributes in the tag 

I use "property" but not "name", so when the name is set to "null" I am 
screwed... thanks for the help!!!

Have you warned the taglib developers about it? (I'll be building Struts 
1.1b with this fix for internal use.)

RE: Problems with optionsCollection tag and Weblogic 6.1

[Arnaud Heritier]

I don't know if it is the source of the problem but in struts 1.1 B1 the code of 
OptionsCollectionTag is initialized with :

protected String label = "label";
protected String name = Constants.BEAN_KEY;
protected String property = null;
private String style = null;
private String styleClass = null;
protected String value = "value";

but the release method defines :

label = null;
name = null;
property = null;
style = null;
styleClass = null;
value = null;

so label, name and value don't have their default values.

it can produce the error.


Do you used the name and value attributes in the tag

RE: Problems with optionsCollection tag and Weblogic 6.1

[Arnaud Heritier]

I didn't watch the code but the difference between tomcat and weblogic is that 
weblogic reuse the taglibraries in the same page.
Tomcat create a new TagClass for each tag instance while Weblogic reuse the first 
instance and call the release method.

This method should reinit all default values in the release method.
I'm using struts 1.0.2 with WLS 6.1 SP2 and i don't have any problem.
But I know that there's a lot of bug in WLS 6.1.

Problems with optionsCollection tag and Weblogic 6.1

[Marcelo Vanzin]

Hello there,

I've started to use Struts 1.1, and one of the things I was testing was 
the "html:optionsCollection" tag, to replace one we coded here (based on 
html:options) that did the same thing.

Everything worked fine when testing in Tomcat, but when running our JSPs 
in Weblogic (6.1 sp1) something realy strange happens.

The first time the tag is called, it works fine. But if you call it a 
second time in the same page, it fails with an exception:

javax.servlet.jsp.JspException: Cannot find bean null in scope null
at org.apache.struts.util.RequestUtils.lookup(RequestUtils.java:692)
at 
org.apache.struts.taglib.html.OptionsCollectionTag.doStartTag(OptionsCollectionTag.java:217)

I have a page with 4 calls to this tag, and it always fails in the second 
call. If I comment the 1st one, then it will fail on the 3rd (and the 
one that previously caused the exception will render fine).

I've taken a look at the tag code, and it does not seem to have anything 
unusual, so I think this is an issue with Weblogic.

Has anyone seen this behaviour, and has some idea of a workaround?

(We're struggling to install sp2 now, maybe when we manage to install it 
this bug may be fixed, who knows...)
