DynaAction or Map Backed Form?

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)

Documents (documentID,documentName)

 

I want to populate a set of checkboxes for each service such that I achieve:

<input type="checkbox" name="serviceName[0].id"
value="documentID">documentName

 

Any ideas?


Thanks,

 

Amin

I've been able to "hack" it using logic:iterate:

 

<logic:iterate name="allRequiredDocuments" id="service">

<bean:write name="service" property="serviceName"/>&nbsp:

<logic:iterate name="service" property="requiredDocuments" id="document">

<input type="checkbox" name="<bean:write name="service"
property="serviceId"/>" value="<bean:write name="document"
property="value"/>"><bean:write name="document" property="label"/>

</logic:iterate>

</logic:iterate>

 

Problem is, I lose my counter, and the ability to use validation . there has
got to be a better way!

 

Thank,

 

/A

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="DocumentID">DocumentName

 

---

<input type="checkbox" name="Catering[0].id"

value="001">Contract

 

<input type="checkbox" name="Catering[1].id"

value="002">Deposit

 

<input type="checkbox" name="Party[0].id"

value="001">Contract

 

<input type="checkbox" name="Party[1].id"

value="002">Deposit

 

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

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.

Sorry... to add...

 

Each Service may have a unknown set of documents...

 

E.g. Services:

 

      001 Catering

      002 Party

 

Documents:

      001 Contract

      002 Deposit

 

Should yield:

 

<input type="checkbox" name="Catering[0].id"

value="001">Contract

 

<input type="checkbox" name="Catering[1].id"

value="002">Deposit

 

<input type="checkbox" name="Party[0].id"

value="001">Contract

 

<input type="checkbox" name="Party[1].id"

value="002">Deposit
