Re: Indexed Property
I don't know how helpful those examples are in reality as there are a
few details missing..
So here's an example.
Personally i like nesting forms although this isn't to everyone's
taste. The example uses LazyList to allow you to scope the form to
request and the example was provided by Paul Chip on the list a few
weeks back.
// action form
import org.apache.struts.action.ActionMapping;
import javax.servlet.http.*;
import java.util.ArrayList;
import java.util.List;
import org.apache.struts.action.ActionForm;
import org.apache.commons.collections.ListUtils;
import org.apache.commons.collections.Factory;
public class ItemsForm extends ActionForm {
private List itemList;
public ItemsForm() {
initLists();
}
private void initLists() {
Factory factory = new Factory() {
public Object create() {
return new ProductForm();
}
};
this.itemList = ListUtils.lazyList(new ArrayList(), factory);
}
public List getItems() {
return itemList;
}
public void setItems(List itemList) {
this.itemList = itemList;
}
public ItemForm getItem(int index) {
return (ItemForm) itemList.get(index);
}
public void setItem(int index,ItemForm item) {
this.itemList.add(index,item);
}
public void reset(ActionMapping mapping,
HttpServletRequest request) {
super.reset(mapping, request);
initLists();
}
}
//ItemForm
public class ItemForm extends ActionForm {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
//ItemsAction [i'd use LookupDispatchAction]
ItemsForm theForm = (ItemsForm) form;
ItemForm item = new ItemForm();
item.setName(First Item);
ItemForm anotherItem = new ItemForm();
anotherItem.setName(Second Item);
theForm.setItem(0,item);
theForm.setItem(1,item);
// struts config
form-bean name=itemsForm type=ItemsForm /
action path=/populate name=itemsForm scope=request ...
action path=/save name=itemsForm scope=request..
//jsp
html:form path=/save.do
logic:iterate id=item name=itemsForm property=items
html:text name=item property=item indexed=true /
or
c:forEach var=item items=${itemsForm.items}
html:text name=item property=item indexed=true /
Sorry I didn't think about the potential confusing of using item
quite so much.. But this should help close a few gaps.

indexed property problem
Hi Mark!
thanks for your answer

Re: indexed property problem
I thought you were trying to get a mapped property.
What does the structure look like? I cant see what you're drilling to.

Re: indexed property problem
i was trying to figure out how to use indexed properties.
in the end I want to pass a collection of name/value pairs to the form,
which the user can edit and then check those and maybe pass the new values
to business logic.
at the moment i'm trying to do this with two String[], one called keys the
other one called values.
For passing those values to the browser, I try using indexed propertie.
As I'm not sure how it has to look like in html so that struts will
populate the ActionForm I'm stuck with the html:text tag, which I can't
make work the way I'd like it to
testPrimKey is a String[] which should put values into the html,
which should get put into the ActionForm, which has an indexed
property called 'keys'
so if I'm guessing right it should look in the end like
input type=text value=k1 name=keys[0] /
but if I have that i get a
ServletException: BeanUtils.populate
..(RequestUtils.java:1254)
root cause
ArrayIndexOutOfBoundsException
java.lang.reflect.Aray.set(Native Method)
...
so maybe that means, the html syntax is ok; but i don't know..
:/

Re: indexed property problem
went through the beanutils code to find the reason for the ArrayIndexOutOfBounds. found that it doesn't use my setter method, which would adjust the array size, but just my getter method (which returns an array, which isn't big enough); moving over to lists instead so i suppose my html was correct. the html:text issues are still not working anyway :/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The getAgencyFileInfo method is returning an ArrayList of AdminAgencyFileSetupForm objects and struts is correctly retrieving fileDirectory and pollingInterval values. If I'm reading the Indexed property FAQ correctly struts should call getAgencyInfo(int index) to first retrieve the correct AdminAgencyFileSetupForm object and then call setFileDirectory(page_field_data) and setPollingInterval(page_field_data). After changing 1 set of fields on the page the log shows: , agencyInfo[1].pollingInterval, [1567]) 2004-02-18 21:33:53,088 - Entering getAgencyInfo(1) 2004-02-18 21:33:53,088 - Target bean = optionSelected = 'null' action = 'null' saveBtn= 'null' agencyId = '3' fileDir= 'File Directory 1' pollIntvl = '1' 2004-02-18 21:33:53,088 - Target name = pollingInterval 2004-02-18 21:33:53,088 - Skipping read-only property 2004-02-18 21:33:53,088 - setProperty( optionSelected = 'null' action = 'null' saveBtn= 'null' agencyId = 'null' fileDir= 'null' pollIntvl = 'null' So, getAgencyInfo(index) is being called, but struts can't seem to find the setPollingInterval(String) method (and it is defined), assumes it is read-only and skips. I've tried every permutation for defining the iterate and text options and methods and nothing seems to work. Would a more experienced struts developer be so kind as to let me know what the heck might be wrong here?..Again, TIA, Gary - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

validate indexed property with DynaValidatorActionForm
Can this be done? I have an Array of my customer objects as the indexed property. Nathan Maves Sun Microsystems - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Indexed Property in JSP
Hello,
We are trying to implement common master-detail records using indexed
properties and beans.
We would like take a single bean with various data and place in a
dynaform bean as multiple occurrences.
The single bean was created with all the getters and setters. And the
dynaform bean was created as followed:
form-bean name=transtudent
type=org.apache.struts.action.DynaActionForm
form-property name = lines type=SPermitForm[] size=4 /
Our Jsp page tries to retrieve the 4 lines within transtudent and cannot
find a setter for 'ssn'. This happens to be one of many fields within
the single bean and this setter/getter is coded and been used.The
error we get is No getter method for property ssn in bean lines The
Jsp follows:
html:form action=reviewPurchases.do
c:forEach var=lines varStatus=status
items=${transtudent.map.lines}
c:out value=${status.index +1}/
html:text indexed=true name=lines property=ssn/
/c:forEach
/html:form
Can anyone give us some insight as to why we are getting this error message?
Many thanks,

best way to handle an indexed property and a textarea
Hi all, I want to use an indexed property with a textarea. Line 0 in the textarea should be array[0] etc. What is the best way to do this? Right now, I'm thinking about writing a custom tag, subclassing TextareaTag and splitting up the data something like value.split(\\r\\n); Is there a more simple way?

RE: best way to handle an indexed property and a textarea
I needed this feature in one place of my application and made it but
didn´t subclass TextAreaTag, neither created a custom tag (thought i
should). In fact, now that I see it, it's a little messy :P. I know it
can be done better, but it's just only as an idea of what i did and a
starting point for you to solve this problem:

RE: Indexed Property in JSP
Besides the other problem with the order of parameters to the setter,
you also have two setters for the same property. You'll need to change
the other setter (and the resulting property name) in order for this to
work.
Also, I believe you can remove the 'indexed=true' attribute, as you're
doing your own indexing.

First of all, you need lazy initialisation in your form.//i have assumed the Beans as
list here.
public TestBean getBean(int index){
while(index = this.getBeans().size() ){
this.getBeans().add(new TestBean());
}
return (TestBean)this.getBeans().getObject(index);
}
Now in your jsp, when you say html:text name=testForm
property=%=\bean[\+i+\].b\%/ , it will be interpreted as
testForm.getBean(i).setB(String )when the form is submitted.And this should work.

Subject: Help needed : cannot resend an indexed property to request
Hello,
I experience big difficulties resend an indexed property of a form as
part of a request.
I build a super-simple code sample to share with you so you can help me
find the trick.
I have a form named TestForm; It has one property named 'beans' that is
an array of TestBean. TestBean is a bean that as two strings properties
: 'b' and 'c'. I put the class code below.
I have two struts actions : '/Test' and '/Validate'.
- '/Test' populates the form (especially the 'beans' property) and
forwards to the JSP 'test.jsp'.
- 'test.jsp' displays basic a form property as well as a list (indexed
property).
- 'Validate' is the action called by the form included in 'test.jsp. It
does nothing but forward back to the JSP 'test.jsp'.
I included the code of those two actions as well as the declarations in
struts-config.xml.
HERE IS MY PROBLEM :
If I use the 'test.jsp' file below, I get an exception
InvokationTargetException when I hit the validate button (submit button
of the form). I aded the JSP an the exception from BeanUtils.populate()
below.

Help needed : cannot resend an indexed property to request (2)
I really get crazy with Struts indexed properties.
I just posted a message about big difficulties resend an indexed
property of a form as part of a request. I made some progress in
debugging and the result is quite SURPRISING !
I build a super-simple code sample to share with you so you can help me
find the trick.
I have a form named TestForm; It has one property named 'beans' that is
an array of TestBean. TestBean is a bean that as two strings properties
: 'b' and 'c'. I put the class code below.
I have two struts actions : '/Test' and '/Validate'.
- '/Test' populates the form (especially the 'beans' property) and

property).
- 'Validate' is the action called by the form included in 'test.jsp. It
does nothing but forward back to the JSP 'test.jsp'.
I included the code of those two actions as well as the declarations in
struts-config.xml.
HERE IS MY PROBLEM :
If I use the 'test.jsp' file below, I get an exception
InvokationTargetException when I hit the validate button (submit button
of the form). I added the JSP an the exception from BeanUtils.populate()
below.

Here is the exception :
java.lang.reflect.InvocationTargetException
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
.../...
at
org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:808)
I think I did everything OK:
- Class TestForm has the following methods
public TestBean[] getBeans();
public void setBeans(TestBean[] beans);
public TestBean getBean(int index)
public void setBean(int index, TestBean bean)
- The logic:iterate tag of 'test.jsp' file has an 'id' attribute equal
to the attributes 'name' of the nested html:text tags (as required)
Here is what are my debugging findings. I traced the populate() method
of Struts class BeanUtils. It invokes the public TestBean getBean(int
index) method with an Integer argument and not an int one !!
The exception happens in method public static Object
getIndexedProperty(Object bean,String name, int index) of class
org.apache.commons.beanutils.PropertyUtils with the following arguments:
- 'bean' : the TestForm instance
- 'name' : bean (String)
- 'index' : 1 (int)
In this routine, it finds public TestBean getBean(int index) in the
form's class puts it in a 'readMethod' local variable and executes :
Object subscript[] = new Object[1];
subscript[0] = new Integer(index);
try {
return (readMethod.invoke(bean, subscript));
} catch (InvocationTargetException e) {
.../...
}
= STRUTS CALLS the public TestBean getBean(int index) method with an
Integer argument, and not an int.
Does anybody have an idea about this problem ?
Thanks in advance for your help.

Re: Indexed property names - the real story
The problem is that you end up having two identically named methods that return
different types. How is the compiler supposed to know which one to use? I had this
same problem myself for a while, because you are right that is what seems to follow
JavaBean specs. But your solution is exactly what you should do, you are still
following spec because you do have a getter method with the correct name. You just
also have an additional getter method to return one within the List. I think this
answers your question.

The problem is naming of the getter for my list of line items. At first I

With the indexed getter/setters as above, it does not work. However, if I

names then getCurrentLineItems and setCurrentLineItems instead of
getCurrLineItems and setCurrLineItems). This appears to be contrary to all

to clear this up.
With the matching names for indexed properties I could not get my JSP page

RE: Indexed property names - the real story
Linda,
Thanks - that cleared things up. Things are working great now that I let the
indexed methods use a different name. Many of the examples and howtos on
indexed properties are not at all clear on this.
The list methods turn out to only be needed by my action class, so the fact
that their names do not correspond to the the property= name on my JSP does
not really matter.

to see the line items. I tried the logic:iterate, nested:iterate and
logic-el:iterate variations of the Struts iterate tag. I also tried using
a JSTL c:forEach loop.
In my action, I set the form bean in the request, could print the form bean
and see all of the line items, . But when it got to the JSP page, BeanUtils
said there currLineItems property was empty.
After deciding that there might be a problem with my property names
(grasping at straws), I discovered that using different names for the
indexed methods seems to have fixed things.
Any ideas on why this is happening. Better yet, how should things work?
I've cut down a piece of my JSP page and my form bean below, trying to keep
enough info without making it too long to read.

Indexed Property!
Hi, I am unable to get a good handle of Indexed Property(ies) This is what i want to achieve. The users need to specify their interests when they register and their options are provided via checkboxes - say Sports, Politics and Computers I presume the attribute in the form object should be a collection object say an ArrayList How would the jsp look like for the Check Boxes? Appreciate some code samples. I presume that all the selected objects (lets' say the User Selects Sports Computers) would be sent in the Action Form when the user hits submit Eagerly awaiting for some Code Samples TIA Manglu - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Indexed Property Problem.
Hi All, I know this question would have been posted earlier also. I want to know how to work with the indexed form fields and their property in the action form class.

RE: Repost: Validator indexed property not working in Struts 1.1 Final Release
Thanks, I have opened a bug report on item one, it is at http://nagoya.apache.org/bugzilla/show_bug.cgi?id=21254. Regarding the second item, is there a paticular reason that the validator is designed to stops validating a list of values on the first failure? This morning I actually modified Validator.java so that it validates all memebers of the list and saves error messages for them all. So now I get it to display like this: value is mandatory value is mandatory value is mandatory This is of course not very clear to the user, because I really wanted is to display: nameList value 1 is mandatory nameList value 2 is mandatory nameList value 3 is mandatory I guess I still need to figure out a way of contructing the error messages in a different way so that it works for both indexed and non-indexed property. On the other hand, the validwhen rules that's supposed to come after 1.1 final, will it be able to handle this kind of validation? How difficult it would be possible to plug that piece into Strut 1.1? The reason I ask is because it will be much difficult for me to sell to the management the idea of delivering our project on nightly build than on Struts 1.1 final. Thanks a lot.

Invalid indexed property ?!
I posted this before, but I didn't even get a response saying it was a
dumb question, not worth answering, so I'll ask again because I am
desperate.
I've got to finish this up soon, and I am stumped.
Again, sorry for the length - I just want to be clear.
I have a form that need to collect some information about a user, using
checkbox groups like so:
Bourbon
[] Jim Beam
[] Makers Mark
[] Blantons
Scotch
[] Johnnie Walker
[] Macallan
[] Lagavulin
Beer
[] Budweiser
[] Heineken
[] Duvel
Users can select 0 or more from each category, and I would like to use
multibox to create the checkbox groups.
I created a HashMap of String[]s like so:
public HashMap getDrinksList() {
drinks = new HashMap();
drinks.put(Bourbon, new String[]{Jim Beam,Makers
Mark,Blantons});
drinks.put(Scotch, new String[]{Johnnie
Walker,Macallan,Lagavulin});
drinks.put(Beer,new String[]{Budweiser,Heineken,Duvel});
}
In my ActionForm I have:
private HashMap drinkPrefs = getDrinksList();
private String[] selectedDrinks;
public String[] getSelectedDrinks(String key) {
if(drinkPrefs.containsKey(key)) {
return (String[]) drinkPrefs.get(key);
} else {
return new String[]{};
}
}
public void setSelectedDrinks(String key, String[] selDrinks) {
drinkPrefs.put(key, selDrinks) ;
}
In my jsp I have:
c:forEach var=drinkType items=${drinksList.keySet}!-- there is
wrapper method for .keySet() --
h3bean:write name=drinkType//h3
c:forEach var=drinkItem items=${drinksList[drinkType]}
html-el:multibox property=selectedDrinks[${drinkType}]
bean:write name=drinkItem/
/html-el:multibox
bean:write name=drinkItem/
/c:forEach
/c:forEach
I would expect to get a list of checkbox groups like I laid out above,
but instead I get:
java.lang.IllegalArgumentException: Invalid indexed property
'selectedDrinks[Bourbon]' at
org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyUt
ils.java:404)...etc etc.
What am I doing wrong? Where can I get more detailed information about
multibox and indexed properties?

Re: Invalid indexed property ?!
Instead of this tag...
html-el:multibox property=selectedDrinks[${drinkType}]
...try this one...
html-el:multibox property=selectedDrinks(${drinkType})
...basically the square breaces are for indexed properties. The round ones are
for maps. You're trying to drive a map based property, so use the round ones
instead. The JavaBean specification defines how these things should be done...

I posted this before, but I didn't even get a response saying it was a
dumb question, not worth answering, so I'll ask again because I am
desperate.
I've got to finish this up soon, and I am stumped.
Again, sorry for the length - I just want to be clear.
I have a form that need to collect some information about a user, using
checkbox groups like so:
Bourbon
[] Jim Beam
[] Makers Mark
[] Blantons
Scotch
[] Johnnie Walker
[] Macallan
[] Lagavulin
Beer
[] Budweiser
[] Heineken
[] Duvel
Users can select 0 or more from each category, and I would like to use
multibox to create the checkbox groups.
I created a HashMap of String[]s like so:
public HashMap getDrinksList() {
drinks = new HashMap();
drinks.put(Bourbon, new String[]{Jim Beam,Makers
Mark,Blantons});
drinks.put(Scotch, new String[]{Johnnie
Walker,Macallan,Lagavulin});
drinks.put(Beer,new String[]{Budweiser,Heineken,Duvel});
}

Indexed Property
In order that my javascript validations run, I can't have my html field names like name[0], name[1] ... now I need to have multiple elements in my form with the same name. In this case though, I wont be able to populate my form bean which has methods setName(int, String)/ getName(int) and attribute name[]. how should I go about it. I am sure someone must have faced a similar situation.

Re: Invalid indexed property ?!
Thank you! Thank you! Thank you!
Now, I must go slam my head into the desk a few times for not figuring
that out myself. I recall seeing somewhere the the dot, and both sets
of braces were equivalent, and it stuck in my head. I'll try to find it
to see if it should be corrected.

Instead of this tag...
html-el:multibox property=selectedDrinks[${drinkType}]
...try this one...
html-el:multibox property=selectedDrinks(${drinkType})
...basically the square breaces are for indexed properties. The round
ones are
for maps. You're trying to drive a map based property, so use the
round ones
instead. The JavaBean specification defines how these things should be
done...

Setting and Getting indexed property
Hi All,
I am having problem setting and getting indexed property of a form bean.
I have a form bean:
public class ExampleForm extends ActionForm {
private String id[];
private String name[];
private String address[];
public String getIdIndexed( int index )
{
return ( id[index] );
}
public void setIdIndexed(int index, String value)
{
id[index] = value;
}
. And so on
}
With appropriate getter and setter methods.
Now in my jsp page I am trying to access these fields and display them
in a table format. Something like this:
logic:iterate id=foo name=exampleForm property=id indexId=ctr
tr align=center valign=middle
tdhtml:text name=exampleForm property='%= idIndexed[
+ ctr + ]%'//td
tdhtml:text name=exampleForm property='%=
nameIndexed[ + ctr + ]%'//td
tdhtml:text name=exampleForm property='%=
addressIndexed[ + ctr + ]%'//td
/tr
/logic:iterate
I want to have the same form bean for create and edit page of the
entity. So in create page I will have a table with blank fields and in
edit page I will have prepopulated fields. Also in edit page I shud be
able add more rows for the table. Now I don't know what property name to
give in create page of the entity. Above code works fine when form bean
is already populated, but problem comes when you want to create the
entity. Do I need to initialize the array? And of what size? As I want
it to be dynamic. Also in create page I want some default number of rows
with blank pages. What shud be the property name for those text fields?
Please help me. I am stuck coz of this problem.
Thanks and Regards
Ritesh

}
public void setIdIndexed(int index, String value)

. And so on
}
With appropriate getter and setter methods.
Now in my jsp page I am trying to access these fields and display them
in a table format. Something like this:
logic:iterate id=foo name=exampleForm property=id indexId=ctr
tr align=center valign=middle
tdhtml:text name=exampleForm property='%= idIndexed[
+ ctr + ]%'//td
tdhtml:text name=exampleForm property='%=
nameIndexed[ + ctr + ]%'//td
tdhtml:text name=exampleForm property='%=
addressIndexed[ + ctr + ]%'//td
/tr
/logic:iterate
I want to have the same form bean for create and edit page of the
entity. So in create page I will have a table with blank fields and in
edit page I will have prepopulated fields. Also in edit page I shud be
able add more rows for the table. Now I don't know what property name to
give in create page of the entity. Above code works fine when form bean
is already populated, but problem comes when you want to create the
entity. Do I need to initialize the array? And of what size? As I want
it to be dynamic. Also in create page I want some default number of rows
with blank pages. What shud be the property name for those text fields?
Please help me. I am stuck coz of this problem.
Thanks and Regards

RE: Setting and Getting indexed property
Ritesh,
Check the example at www.keyboardmonkey.com or the nested tag lib in
Struts. It may help with the presentation. Though, if you add an object
and need to save to a DB, you will likely need to use a lazyList.
Regards
Al

Stupid indexed property DynaActionForm problem/question
Before anyone flames me, I have read through the archive, and as someone
already said, there is info in there, but no concrete basic examples.
Here's the formBean I'm trying to handle:
form-bean name=familyForm
type=org.apache.struts.validator.DynaValidatorForm
form-property name=address type=java.lang.String/
form-property name=city type=java.lang.String/
form-property name=state type=java.lang.String/
form-property name=zip type=java.lang.String/
form-property name=homePhone type=java.lang.String/
form-property name=status type=java.lang.String/
form-property name=firstName type=java.lang.String[]/
form-property name=lastName type=java.lang.String[]/
form-property name=cellPhone type=java.lang.String[]/
/form-bean
In short, there are some fields that are the same for everyone, and some
fields that are unique to each person. I can place a hard limit on how many
firstNames there can be, but I want the code to refer to a constant
somewhere, say Constants.MAXPEOPLE or something. I'm not trying to have
an array of some object type (there WAS somewhat of an example for that in
the archive), just flat out strings.
I know the JSP will look something like:
html:form action=saveFamily
html:text property=address/
html:text property=city/
html:text property=state/
html:text property=zip/
html:text property=homePhone/
html:text property=status/
logic:iterate ?
html:input ???/ for firstName
html:input ???/ for lastName
html:input ???/ for cellPhone
/logic:iterate
html:submit/
/html:form
Then from my actions I can do this:
DynaActionForm dynaForm = (DynaActionForm) form;
address = dynaForm.get(address).toString();
city = dynaForm.get(city).toString();
state = dynaForm.get(state).toString();
zip = dynaForm.get(zip).toString();
homePhone = dynaForm.get(homePhone).toString();
status = dynaForm.get(status).toString();
for (int i = 0; i ???; i++) {
thisFirstName = dynaForm.get(firstName, i).toString();
thisLastName = dynaForm.get(lastName, i).toString();
thisCellPhone = dynaForm.get(cellPhone, i).toString();
}
Can someone fill in the ??, so to speak?

How rto set and get indexed property in jsp page
Hi I am not able to set and get the indexed property in jsp file. Please Help Me Regards Shashi
Iterate + indexed property arghhh....
Hello,
I wonder whether somebody can help, I'm using the logic iterate tag to
loop through a number
of items producing a delete button for each of the items. When the
delete button is
clicked I want to delete that particular item. Using the below:
html:submit indexed='true' onclick=return confirm('Confirm
Delete?'); property='action'
bean:message key=questionoption.button.delete/
/html:submit
I produce a list of buttons which SHOULD appear like follows:
input type=submit name=action[0] value=Delete
input type=submit name=action[1] value=Delete
input type=submit name=action[2] value=Delete
but instead the name appears like this:
input type=submit name=action[0] value=Delete
With [0] being outside the bracket.
Can anybody tell me why this is? Does it make a difference if I use '
to enclose the values
or whether I use to enclose the values. It would seem that it does so
does anybody know
the EXACT syntax for specifying a HTML submit button? Should I be using
a nested:submit
component? Does that really make any difference?
Also on the server side how would I catch which button has been pressed?
I can't use:
String action = (String)request.getParameter(action);
Because the index causes a problem,
Many thanks in advance for any help or tips you can provide me with,
this seems to be the last
part of my problems.
Jon.

problems with nested indexed property
When I'm trying to submit the following form, something funny happens. The subprocess.name property is set, but the indexed properties are not set. The indexed properties (subproces.subprocesList.starttime and s.s.endtime) are set to their initial values; the request parameters are not copied properly into the ActionForm. The appropriate getters and setters are provided in the ActionForm and Subprocess-class. Anyone have any idea what might cause this problem? html:form action=savesubprocess.do html:text property=subprocess.name / nested:iterate property=subprocess.subprocesList startijd: nested:text property=starttime / eindtijd: nested:text property=eindtime /br /nested:iterate /html:form Cheers, Ruud. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: indexed property
I thought because Struts uses BeanUtils that it would have been able to figure this out for you byusing html:text property=endDateIndex[0]/ You cant do this: html:text property=endDateIndex value=endDateIndex[0]/ because struts treats whatever is in the value parameter as a literal, and does not perform a lookup. Because the TextTag uses RequestUtils.Lookup method to lookup the property which in turn, uses the very nifty BeanUtils from commons to find the value from our array based form property. Now, BeanUtils offers us some cool functionality: http://jakarta.apache.org/commons/beanutils/api/org/apache/commons/beanutils/PropertyUtils.html Indexed (name[index]) - The underlying property value is assumed to be an array, or this JavaBean is assumed to have indexed property getter and setter methods. The appropriate (zero-relative) entry in the array is selected. List objects are now also supported for read/write.

Hi,
I was just trying to prevent dates being reset in a textbox.
bean:define id=startdate name=form property='%=
startDateIndexed[ + 0 + ] %'/
Since my form attributes were all String[] I use
public String getStartDateIndexed( int index ) {
return ( startDate_[ index ] );
}
and then I use
html:text property=startDate styleClass=dropdown maxlength=10
size=12 value=%=startdate.toString()%
I do see exceptions with this.

My form starts with the following
private String[] startDate_ = new String[]{ 22/02/2002 };

Indexed property problem
Hello, I have a problem setting form properties that have a type of String[]. I have seen similar problems in other messages that came around, but now of them or their answers seem to address the specfic issue we encountered. Somewhere in Struts (see stack trace below) the Array.set() method tries to fill in the String array using the indices from the form parameters of the submit request. The array that that method uses or gets passed has not been allocated to be able to hold the number of parameters we tries to pass on. In fact it is of String[0]. Somehow you would expect that either Struts of the DynaActionForm beans should make an extra step and pre-allocate the array before setting the individual array elements. This does not seem to be done. My questions are: - do we use the feature in the wrong manner? - do we need to specify that array size somewhere, with which Struts can pre-allocate the array? - did we stumble on a bug? Any input appreciated, Richard Kooijman Here follows some details on this issue: I have this defined in my struts-config.xml: form-bean dynamic=true name=soortopvanglocatieForm type=org.apache.struts.validator.DynaValidatorForm form-property name=vorm type=java.lang.String / form-property name=voorkeurenKinderdagverblijfVoorkeur type=java.lang.String[] / form-property name=voorkeurenBuitenschoolseopvangVoorkeur type=java.lang.String / form-property name=voorkeurenBuitenschoolseopvangBasisschool type=java.lang.String / form-property name=voorkeurenHalvedagopvangVoorkeur type=java.lang.String / /form-bean Note the array of String as the type of voorkeurenKinderdagverblijfVoorkeur.

Things start to get messy when I essentially try to add or delete a html:text field (by trying to change the array of voorkeurenKinderdagverblijfVoorkeur in the background). When I hit one of the two buttons I defined, Struts start parsing the POST information but halts in the bean populate() section: java.lang.ArrayIndexOutOfBoundsException at java.lang.reflect.Array.set(Native Method) at org.apache.struts.action.DynaActionForm.set(DynaActionForm.java:457) at org.apache.commons.beanutils.PropertyUtils.setIndexedProperty(PropertyUtils.java:1414) at org.apache.commons.beanutils.BeanUtils.setProperty(BeanUtils.java:1013) at org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:808) at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1097) at org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:798) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:254) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1422) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:523) I debugged this in the source and the array that is to be set by Array.set is of type String[0].

Indexed property
Hello, I understand this topic has been discussed before, so I apologize for posting this again. Using strtus 1.1-b3, I'm creating a form bean that contains a collection(ArrayList) and use it to populate the jsp using the iterate tag. With or without indexed attribute in the form elements (i.e html:text Indexed=true), I got the jsp to populate the data. My problem is mostly in the action class where the form gets submitted. If I don't set indexed=true, then the jsp is populated correctly. But when the submit button is clicked, the the collection is always set to null. If I set indexed=true, and if I put indexed getter and setter methods along with regular getter and setter for the collection, I would get No getter method for property error when jsp is created. If I set indexed=true, and if I don't have indexed getter and setter, then jsp is created fine with correct indexed form field name, etc but I would get java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 error on submit. I've been struggling with this issue since yesterday, and I'm running out of ideas now. Any comments would be greatly appreciated. (And hopefully I described my problem for you to understand.) Yujin P.S: my apologies for not posting the sourcecode. I don't want to post it as is, and I'm a bit tight on time to meet the deadline, so I didn't want to spend too much time on reformatting the source code I have.

Prepopulating DynaActionForm which has an indexed property

I could have done this by using an initial property and set the size but the size changes dynamically.

Re: Prepopulating DynaActionForm which has an indexed property
I'm doing the same kind of thing, I don't think dynaform supports arrays so that might explain why it isn't digging what its being sent. The mapped backed action form is the puppy you need to get your head 'round (as do i). Read the latest docs on 'map backed action forms'.. This basically puts an undefined amount of form values into a hash map. To the best of my knowledge you don't define these fields in config.xml.

problem getting indexed property values
Hello, I'm having a hard time getting the value of an indexed property to my Action classes. Essentially, on my JSP I've got html:select property=nestedClass.nestedBeans[x].value size=1 html:options ... / /html:select where nestedClass is (of course) a nested class within my ActionForm class, and nestedBeans is an array of beans with an attribute value. What's perplexing to me is that the correct values are coming up in my JSP page (so my syntax must be correct). After I submit the form, though, every bean in nestedBeans is reset to 'null'. I have a custom reset function in the ActionForm, and it does not reset nestedClass or any of it's values. Has anyone run into similar problems? I can include code if it would help.

RE: problem getting indexed property values
if you *really* want to do it this way, you need to have an embedded scriptlet: html:select property=nestedClass.nestedBeans[% request.getParameter(index) %].value size=1 or something like that better is to refer to a unique property of the action form which is the selected item, and a collection that houses a copy of the list of objects that possess the property like this: html:select name=nestedClass property=nestedBeanValue html:options collection=nestedBeans property=value labelProperty=label/ /html:select if you're wedded to index, make it a property of your objects in the list -JT -Original Message- From: Matt Sales [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 25, 2002 10:27 AM To: Struts Users Mailing List Subject: problem getting indexed property values Hello, I'm having a hard time getting the value of an indexed property to my Action classes.

RE: Nested Indexed Property
OK, I think I see what you're trying to do better now. Email really is one of the worst possible ways to discuss things of technical subtlety, but it's all we got, so patience and careful reading is sometimes required... Instead of trying to generate a list of objects with a logic:iterate that are then sent as request parameters to the Action and used by the controller to populate the ActionForm, you seem to be trying to refer to an index on a list of objects that exists already. If I'm wrong, then let me know and I'll suggest something else. Otherwise, I have the following thoughts/suggestions: You may want to refer to some unique identifier rather than using the array index. Or make the index a property of the object which is essentially the same thing. That way, you can do things like use html:select to specify the value of the identifier, and html:options to specify the collection of objects. In your case, you'd select a customer id/index on the first page which would correspond to the property used by the html:select on the second. The collection used by html:options is your array of customers. What I guess I don't get is why you need to refer to an array when you're editing fields in the customer object the user selected. Why not just have the user select a single object from the array, and have that object be a form bean that you then compare to the corresponding object in the array once the user has submitted the form? That way, you're not in the business of selecting and editing simultaneously. If the reason is that the array of customers we're talking about here is actually your object model, you may want to think about the way your application is using the form (ignore the rest of this paragraph if that's not the reason). Usually, it's better to have the FormBeans be copies of the model objects so that you can have a sort of validating DMZ protecting your data-- if you don't agree, poke around and you're sure to find a rant by Craig McC that explains it better than I'm able. The basic idea is to keep the M and the V in MVC separate.

Re: Nested Indexed Property
Not sure what your question is: If you want to do multi row displays or multi row displays, I have beans that implement iterator or collection (getRow). If your want to update multiple beans, you can have such beans within a bean. If you have issues with setters, you can unit test them outside of Struts or webapps. If you have issues with parms or attributes, you can debug them my iterating all the attributes/parms for request/session and see what you have. Try going step by step. Test the setter. Test the parms. Test the iteration. (To me, the main attraction of MVC is that you can unit test each component before using it). V.

So the edit button points (indirectly or otherwise) to the next page which contains a form to edit the data (ie, the bean POINTED TO by the linked list). But now I have problems. 1. What do I put in the html:form tag and the config xml for that matter. 2. How do I have the fact that the bean already exists 3. How do I handle the fact that the bean to use is unknown until run time 4. How do I handle the fact that the bean is referenced by an ArrayList I basically need to edit the contents of a bean that is dynamically allocated to the form at run time. The structure of the bean IS fixed though, so I don't think I'm talking about DynaBeans.

RE: Nested Indexed Property
No, I have never used struts-nested. The documentation says that the indexed property is only for use inside a logic:iterate tag. I'm not inside a logic iterate tag. To put it as simply as possible. Page 1 has a link: a href=page2.jsp?index=5 (and I accept that this might be page2.do!! and page 2 needs to do html:text name=beanwithlist[ index ] property=name / geddit? index is a property generated according to the user selection on the previous page. This is what I need to index the data by. The second page would be a simple, basic edit form but for the fact that I have no idea how to reference the bean it uses because it is part of a linked list in some other bean with a dynamic reference.

How do I handle the fact that the bean to use is unknown until run time 4. How do I handle the fact that the bean is referenced by an ArrayList I basically need to edit the contents of a bean that is dynamically allocated to the form at run time. The structure of the bean IS fixed though, so I don't think I'm talking about DynaBeans. I have thought about (in the action called from the first page) creating a new bean in the request scope just containing the selected bean from the list. This gets really confusing and has issues of its own. Does this make more sense? I'm really stuck here!!! Any help greatly appreciated. Howard On 21 Sep 2002 at 16:19, V.

If your want to update multiple beans, you can have such beans within a bean. If you have issues with setters, you can unit test them outside of Struts or webapps. If you have issues with parms or attributes, you can debug them my iterating all the attributes/parms for request/session and see what you have. Try going step by step. Test the setter. Test the parms. Test the iteration. (To me, the main attraction of MVC is that you can unit test each component before using it). V.

To set the scene may I quote from the documentation: You may also place a bean instance on your form, and use nested property references. For example, you might have a customer bean on your Action Form, and then refer to the property customer.name in your JSP view. This would correspond to the methods customer.getName() and customer.setName(string Name) on your customer bean fine... BUT what if name is a property of an object in the LIST customer. So (working backwards) I want to create the reference: customer.get( i ).setName(string Name) (oversimplified I know). BUT it gets worse the index, i, is actually a property set on the previous JSP page... so its more like customer.get( reqest.getParameter( index ) ).setName(string Name ) ...and of course the form action needs to properly read the current values into the form text fields and then set them back into the correct place. I have no clue how to do this! Any offers?
