[jira] [Commented] (WW-4398) Parameters mapping to java.util.Set of complex type doesn't work

["Josh Mabry (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WW-4398?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14112621#comment-14112621 ] 

Josh Mabry commented on WW-4398:
--------------------------------

Steps to reproduce:
Place the following 2 member variables on an Action with appropriate Getters/Setters:
  private Set<MyInner> myInnerSet; //MyInner is defined below
  private Set<Integer> myIntegerSet;

Add these tags to your JSP to show off:
  <s:hidden name="myInnerSet.idString" value="1"/>
  <s:hidden name="myInnerSet.idString" value="2"/>
  <s:hidden name="myIntegerSet" value="1"/>
  <s:hidden name="myIntegerSet" value="2"/>

Execute Action and see what was mapped onto you Action's member variables.

Expected results:
myInnerSet.size() == 2
myIntegerSet.size() == 2

Actual results:
myInnerSet.size() == 0
myIntegerSet.size() == 2

public class MyInner {
  private String idString = null;

  public String getIdString() {
    return idString;
  }

  public void setIdString(String idString) {
    this.idString = idString;
  }
}

> When you have a java.util.Set of complex objects, the ParametersInterceptor can not map those values onto the set. A Set of complex objects is easily defined as a Set<MyTestClass> where MyTestClass has a String idString as its only property.
