<br><div style="word-wrap: break-word;">Mariano, knowing that ProtoObject does understand doesnotunderstand via is not enough. There are a dozen or two other methods needed <div>in order for a debugger to come up, even to invoke an inspector on ProtoObject subclasses.</div>

</div>Without understanding the details of what you're doing, let me offer<br>
this: </blockquote><div><br>thanks Colin for the help.<br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">try looking for objects that don't inherit from Object. </blockquote>
<div><br>Ok, there are objects that doesn't inherit from Object, and even my proxies don't do that. But.....ProtoObject DOES understands the message #doesNotUnderstand:<br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
Even if<br>
you aren't proxying #doesNotUnderstand:, you can get a recursive DNU<br>
if an object that doesn't understand #doesNotUnderstand: </blockquote><div><br>there cannot be objects that don't understand #doesNotUnderstand: since it is implemented in ProtoObject. <br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
gets<br>
*another* message it doesn't understand.<br>
<br></blockquote><div><br>Anyway, I will think if there can be a situation that happens what you said...maybe there is.<br><br>Thanks a lot !<br><br>mariano<br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
