Find children in a webBean

Question

I'd needed to find a child in a webBean.  I'd used:
OASubTabLayoutBean subTabLayout = (OASubTabLayoutBean)webBean.findChildRecursive("subTabRN");
and gotten null results.  So either that wasn't the name I thought it was, or I was in the wrong bean.
So, how to find the names of the children that were there?
Reading several posts, each with snippets of information, I pieced together the following code:
  public void printWebBeanChildNames(OAPageContext pageContext, OAWebBean webBean) {
    OARenderingContext rc = (OARenderingContext) pageContext.getRenderingContext();
    int cnt = webBean.getIndexedChildCount(rc);
    for (int i = 0; i < cnt; i++) {
      UINode uiN = webBean.getIndexedChild(rc,i);
      System.out.println("getID:" + uiN.getID());
  } // printWebBeanChildNames
The resulting list told me I was in the wrong bean (I recognized the names as belonging to a sibling), which gave me what I needed to fix the problem.
I wanted to post my code snippet, so that those who follow would be able to use it without having hunt down the specific clues.  But the discussion was locked.  So I created a new one.
I hope the code is useful.
Thanks

Perhaps I should add that it was in my CO.  I'd made it a procedure, so I could easily comment out the call, when I no longer needed it.  And, I presume that it would work anywhere you had access to the OAPageContext and OAWebBean.
