Suggested fix submitted from IBM.  Looking to get the fix into next cycle for 1.4.
=============================================================================

Name: vi73552			Date: 04/29/99


The getResourceAsStream and getResource method in
BeanContextSupport both implement a check whether
the BeanContextChild (bcc) making the request is contained 
in the context or not. This is done by calling the containsValue
method of the HashMap which contains the children and
passing bcc as the argument.
But the HashMap only contains instances of BCSChild as
values, so this will always fail resulting in an
IllegalArgumentException.

SUGGESTED FIX **Workaround: The workaround is to overrise the behaviour of the getResrouce and getResourceAsStream functions of the BeanContextSupport, in the user code. ** Suggested Fix Compare: (<)T:\cn130-20010925\src\classes\sov\java\beans\beancontext\BeanContextSupport.java (42346l bytes) with: (>)E:\cn130-userlvl\src\classes\sov\java\beans\beancontext\BeanContextSupport.java (42582l bytes) 366a366 > 650,651c651,654 < synchronized(children) { < isChild = children.containsValue(bcc); --- > > synchronized(children) { > //isChild = children.containsValue(bcc); //ibm@38181 > isChild = children.containsKey(bcc); //ibm@38181 676c679,680 < isChild = children.containsValue(bcc); --- > //isChild = children.containsValue(bcc); //ibm@38181 > isChild = children.containsKey(bcc); //ibm@38181 **Test Case and Failure Data: import java.beans.beancontext.*; import java.io.*; public class Example1 { private static BeanContextSupport context = new BeanContextSupport(); // The BeanContext private static BeanContextChildSupport bean = new BeanContextChildSupport(); // The JavaBean private static String fname = "Readme.txt"; public static void main(String[] args) { // Add the bean to the context System.out.println("Adding bean to context..."); context.add(bean); report(); } private static void report() { try { InputStream s = context.getResourceAsStream(fname,bean); } catch (Exception e) { System.out.println("Exception:"+e); } } } **How root cause of failure was determined IllegalArgumentException ("not a valid child") is thrown.
