OGNL/Struts2 JSP assigning bean to an object

Question

In Struts2 / OGNL page, is it possible to assign any type of bean to an object depending on condition?

For instance,

  <s:if test"%{customer != null}">
       <s:set var="someobject" value="customer">
  </s:if>
  <s:else>
       <s:set var="someobject" value="user">
  </s:else>

Answer 1

Yes, you can. But are you sure you should ?

This seems to be business, not presentation, and hence why in the view and not in the controller ?

Instead of

<s:if test"%{customer != null}">
     <s:set var="someobject" value="customer">
</s:if>
<s:else>
     <s:set var="someobject" value="user">
</s:else>

SomeObject is of type : <s:property value="%{#someobject.class.name}" />

You can use in your action

public String getSomeobject(){
    return (customer!=null) ? customer : user;
}

and in JSP only

SomeObject is of type : <s:property value="%{someobject.class.name}" />

Your use case is more suitable when your action knows nothing about your objects, but then you would be putting a lot of business logic in the view...
