Description Svata Dedic 2001-03-26 07:26:06 UTC 
SourceChildren used by the ClassNode are initialized with SourceElement 
asynchronously. Children.findChild then fails to wait until the initialization 
is completed and returns null prematurely.
Comment 1 Michael Ottati 2001-03-26 20:20:27 UTC 
It is not just Children.findChild. This fix also address the other mechanisms 
to find children.

The Children class supports the following additional methods which should also 
be addressed in this fix. 

nodes()
getNodes()
getNodesCount()
Comment 2 Svata Dedic 2001-03-27 05:46:58 UTC 
Yes, but other Children methods just returns the current state. If nodes are
filled asynchronously (as for example the filesystem nodes), nodes() etc just
returns data available at the time of the call. There are situations where you
don't have fixed set of children, because they can change at any time.

findChild() is special because it is specific query and can (and should) be
handled specially by the data producer.
Comment 3 Svata Dedic 2001-04-02 16:23:54 UTC 
Fixed in 3.2.19, dev-159. SourceChildren instance is attached to its 
SourceElement from the beginning of its existence.
Comment 4 Jan Chalupa 2001-05-05 20:18:55 UTC 
Target milestone -> 3.2
Comment 5 Quality Engineering 2003-06-30 16:43:41 UTC 
Resolved for 3.3.x or earlier, no new info since then -> closing.
