Re: [Openamf-user] Bugs?

Hi Todd,

I'm sorry to answer your email so lately: thank you for your email. 
Actually Flash doesn't lock up using circular references. I'm 
serializing and deserializing a tree whose nodes have both a "parent" 
and a "children" property, so that a parent node points to its children 
and every children points to its parent... and, if I disable openamf 
logging, everything works (probably because I patched 
AMFDeserializer.java as I said in the previous email?). A bit of 
investigation (that actually has been done by a colleague) led to the 
conclusion that is the ASObject.toString() that causes the trouble.

Thank you,

lorenzo
