How to add a list or array as an attribute

cloudcompuser

I need to create a business object that has a list or array or a collection as an attribute. I tried by adding a business group as an attribute of the business object. It doesn't support multiple objects as attributes.

Can someone provide a solution for this ?

Can you please explain more about what you are trying to accomplish?

I can explain the scenario broadly like this. We have a scenario where we would have a Business Object called "Recipient" which would have multiple "claims". We modeled Claim as a BO and Recipient as another. However we do not have a mechanism in which we can model multiple claims within the same Recipient BO.

Could you please specify whats the right modeling approach. And also, whats right Web Service / AJAX call to retrieve such business objects?

Have you looked at the sample applications? They have many examples of the type of relationship you are describing.

As Tom said, there are lots of examples in the sample apps - but just to get you going.

define an attribute in Recipient as Claims set it to "Multiples allowed" then you need to decide whether the relationship of recipient to claims is Peer or Owner (ie can a claim exist without a recipient?).

Then use the field at the bottom to define a related attribute in the Claims BO.

If you want to see details from Claims in a Query result set - don't forget to create shortcuts in Recipients (and vice-versa)

Look at the sample Library App for more info

Thanks Rocket Man.

Based on your post, I found that there is a way in which a BO can relate to another.

For example, a Recipient BO can have an attribute called Claims which is of type “Claim” with multiple selected. Such a cross reference attribute can be single or multi valued.

Irrespective of single valued or multi-valued, the values of the composite objects is not exposed as a web service or through the Forms.

For instance, a FIND ALL Recipient will give only its native attributes; it won’t give any single / multi valued attributes of Claims.

This is true of both web service and the UI search results page.

As per the suggestion, I tried adding a short cut. The short cut values are shown in the form results page if it’s a single valued attribute. Ie, if Recipient had a Claim which is not multi valued; then recipient can have a value claimid which can be a shortcut to Claim.id

However, the same is not applicable for an array or multi valued attribute. Do you know of a way in which multivalued BO attributes’ attributes can be exposed as short cuts?

No you can't do it for multiples, you can however include the referenced attribute in a form as a Table, you can then define which of the cross referenced attributes appear in the table
