Re: Map backed form
Thank you Yasser. Changed the name of the properties file to use the model
class name, it is in same package as the action so no change in location. But
no success.
After reading the link you sent, the text in the properties file should be
Key_xxx & Element_xxx as you said before and should not be KeyProperty (this is
for lists to identify the id inside the
element itself).
I have now tried the @Element on the variable rather than @TypeConversion which
has to be used on setXXX method. This is working now as expected. Not sure why
properties file or @TypeConversion did
not work.

Thanks for all your help.

Re: Map backed form
I have created the below in CompDeferralAction-conversion.properties (action
class is CompDeferralAction). The variable name is deferralCode. But still
struts is populating the value as Long rather
than Integer. Am I missing anything here?
This action is ModelDriven so the deferralCode variable is in a different class.
Looking at the documentation seems like it should be KeyProperty, so I named it
as such.
KeyProperty_deferralCode=java.lang.Long
Element_deferralCode=java.lang.Interger
I have also tried the annotations
@TypeConversion(rule=ConversionRule.MAP, key="java.lang.Long",
value="java.lang.Integer")
public void setDeferralCode(HashMap deferralCode) {
this.deferralCode = deferralCode;
}
Thanks,
Prasanth

Map backed form
Hi, I have a map (Map) but based on the data entered by the user the value in the Map is Double or String. Example if the user enters a value of 10 then it is coming in as double but if the user enters 10.5 then a string is present in the value. Does Struts2 look at the data types of the key and value of the map and set the key and values in the map accordingly? If not, what is the best practice for the declaration of Map, is there a way to force Struts2 to only have Double objects as values? Thanks, Prasanth
[S2] How to use a Map backed form?
Hi all
Using Map backed forms in Struts 1 was really great. I'm wondering
how it works in Struts 2. Looking at the Type Conversion docs (http://
struts.apache.org/2.x/docs/type-conversion.html#TypeConversion-
CollectionandMapSupport) seem to get close to explaining it, but
jumps right into a complex indexed form field example.
Ultimately, I can't get the Map in my Action to populate from the
form correctly, and I'd like to know how to do it. I'm attempting to
generate a bunch of dynamically named textfields like this:
s:iterator value=%{fields} id=field
s:textfield name=myField[%{field}] /
/s:iterator
This gives me fields that look like the following, which I expect:
input type=text name=dynaField[firstField] ... /
input type=text name=dynaField[secondField] ... /
input type=text name=dynaField[thirdField] ... /
input type=text name=dynaField[etc] ... /
The Action that the form submits to looks something like this;
class MyAction extends ActionSupport{
private MapString,String dynaField = new HashMapString,String();
public String execute()throws Exception{
//when I get here, the dynaField property is a valid HashMap that
looks like
//{null=the value of an unpredictable field}
System.out.println(dynaField);
return SUCCESS;
}
//Getter and Setter here
public void setDynaField(MapString,String map){ dynaField = map; }
public MapString,String getDynaField(){ return dynaField; }
}

Not if it will be useful to you but when I generate dynamic forms I do the following thing: The form definition: form-bean name=myForm type=test.MyForm form-property name=paramValue type=java.lang.String[]/ ... /form-bean And then The select: html:select property=paramValue multiple=true html:options collection=entryes property=key labelProperty=value/ /html:select If option is selected String[] contains the Value else contains null. The String[] size is the select options size. I hope to have helped for you!!

multiselect with a map-backed form property
I have a form with a dynamically generated list of constraints that can
be turned on or off, and each constraint has a set of values associated
with it. My form has two relevant fields:
private String[] selectedConstraints;
private Map values;
public String[] getSelectedConstraints() {
return selectedConstraints;
}
public void setSelectedConstraints(String[] selectedConstraints) {
this.selectedConstraints = selectedConstraints;
}
public Object getValues(String key) {
return values.get(key);
}
public void setValues(String key, Object value) {
values.put(key, value);
}
To keep track of which values are associated with which constraint, I
use the string from the selectedConstraints array as the key into the
values map. My jsp page looks like this:
c:forEach var=constraint items=${constraints}
trtd
html:multibox property=selectedConstraints
c:out value=${constraint.propertyID}/
/html:multibox
c:out value=${constraint.propertyName}/
/tdtd
html-el:select property=values(${constraint.propertyID})
html:optionsCollection name=constraint
property=allowableValues/
/html-el:select
...
The above works perfectly fine as long as only want to select a single
item from the select drop-down box. The problem is some of the
constraints can have multiple values, so I changed the select to a
multi-select:
html-el:select multiple=true
property=values(${constraint.propertyID})
But then the form is only ever populated with the *first* string
selected from the multiselect box. Since a map can hold a String[] as
easily as a String, I'm a little confused by this behavior. I tried the
following things with no luck (these changes are in the struts action
that forwards to the jsp above):
1) inserting an empty String array into the values map for each key in
an attempt to coerce the user of String arrays
2) inserting a wrapper class into the map for each key:
public class SelectedValues {
private String[] selectedValues;
public String[] getSelectedValues() {
return selectedValues;
}
public void setSelectedValues(String[] selectedValues) {
this.selectedValues = selectedValues;
}
}
and I updated my jsp to:
html-el:select multiple=true
property=values(${constraint.propertyID}).selectedValues
but that causes the following exception:
javax.servlet.ServletException: BeanUtils.populate
org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1254)
...
root cause:
java.lang.IllegalArgumentException: No bean specified
org.apache.commons.beanutils.PropertyUtils.getPropertyDescriptor(PropertyUtils.java:837)
...
I can get the multiselect to work if I create a String array for each
constraint, but that defeats the purpose since this is supposed to be
dynamically generated. I'm out of ideas for other things to try with the
map-backed approach. Can someone tell me what I'm doing wrong here?
Thanks,
Adam

Map backed form with list of String Arrays
I am having a problem with a map-backed form and html:select with multiple=true.
Would appreciate any help/ideas.
I need to display a set of html:select lists. The number of lists is user-defined
(based on database data) and each select list
must allow more than one choice to be selected.
I settled on using a map property in the form bean as the manual suggests. Everything
works great on initial display, furthermore I
am selecting all values which will be the normal use case for the user.
However, upon return, only a single value is passed in. Should I be using the value
attribute on the html:select tag? I cannot
seem to figure out how to make it work as an array.
Here are the relevant struts/JSTL tags.
c:forEach items=${form1.choiceList} var=valueArray
td style=text-align: center;
c:set var=cList value=${Collection_charChoices[choiceArray.key]}/
html-el:select name=form1 property=choiceLists(${choiceArray.key}) size=6
multiple=true
value=choiceLists($choiceArray.key)
html-el:options collection=cList property=id labelProperty=name/
/html-el:select
/td
/c:forEach
Here is a code snipped I use to inspect the map as it comes in (afer having been
successfully sent out and displayed with all values
selected):
Set keySet = map.keySet();
Iterator ik = keySet.iterator();
while (ik.hasNext()) {
Object key = (String)ik.next();
log.debug(showMap - mapKey='+key.toString()+');
Object value = map.get(key);
if ( value instanceof String[] ) {
String[] valArray = (String[]) value;
for (int i=0;ivalArray.length;i++)
log.debug(showMap - valArray[+i+]='+valArray[i]+');
} else {
log.debug(showMap - value instanceof
'+value.getClass().getName()+');
log.debug(showMap - value='+value.toString()+');
}
}
It shows a simple String object (the first choice in the options list, actually)
rather than the String[] that was sent out.
Thank you again - Richard

RE: DynaAction or Map Backed Form?
It isn't clear what you have to work with. Is services a map of some sort, or is it a collection. Either way you should use the iterate tag in the logic tag set. If you could explain the data structure better, it would be easier to help. -Original Message- From: Amin Lalji [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 07, 2004 12:39 PM To: 'Struts Users Mailing List' Subject: RE: DynaAction or Map Backed Form?

RE: DynaAction or Map Backed Form?
Im not sure how to do it with the iterate tag, I use the c:forEach tag in
the jstl taglib.
It goes something like this:
Assume service is a bean with accessors getDocuments ( ) and getId ( )
Assume document is a bean wit accessors getId ( ) and getName ( )
c:forEach var='service' items='services'
c:forEach var='document' items='service.documents'
input type=checkbox name='${service.id}
value='${document.id}'c:out value='${document.name}'/
c:forEach
c:foreach

Here is the Data structure:
I have two tables (Services, Documents)
I hit the database and pull two separate Collections.
I need to iterate over both collections... here is the relationship:
ServiceID
ServiceName
Documents
DocumentID
DocumentName
So a service object contains a collection of documents
I need to be able to output something like:
input type=checkbox name=ServiceID[0].id
value=DocumentIDDocumentName
---
input type=checkbox name=Catering[0].id
value=001Contract
input type=checkbox name=Catering[1].id
value=002Deposit
input type=checkbox name=Party[0].id
value=001Contract
input type=checkbox name=Party[1].id
value=002Deposit
In my action, I created a DynaActionForm.
I set a java.util.ArrayList property called requiredDocuments in
struts-config.xml
In my action I make the database calls, then I iterate the services
collection creating a RequiredDocumentsBean (contains serviceID,
serviceName, and documents Collection)
I populate the first two properties (serviceID, and serviceName) and then
iterate the documents collection setting a LabelValueBean
Here is the code:
-- snip --
while(sIterator.hasNext()){ // for each service...
RequiredDocumentsBean rd = new RequiredDocumentsBean();
ServiceBeanLocal service = (ServiceBeanLocal)sIterator.next();
rd.setServiceId(service.getId());
rd.setServiceName(service.getServiceName());
Iterator dIterator = documents.iterator();
while(dIterator.hasNext()){ // for each available document
DocumentBeanValue document =
DocumentBeanValue)dIterator.next();
rd.getRequiredDocuments().add(new
LabelValueBean(document.getDocumentName(),document.getId()));
}
requiredDocuments.add(rd);
}
myForm.set(allRequiredDocuments,requiredDocuments);
request.setAttribute(allRequiredDocuments,requiredDocuments);
-- snip --
Thanks

Hello All,
I have the following scenario:
I need to populate a form using a runtime generated set of form
properties...
Essentially I have two collections I pull from a database
Services (serviceID,serviceName)

I want to populate a set of checkboxes for each service such that I achieve:
input type=checkbox name=serviceName[0].id

Any ideas?
Thanks,
