Hi John,<div>Looking at your code, I think you need to call super initialize in the initialize method of the FactorialComponent. Its the "usual suspect" when decorations throw errors.</div><div>John<br><br><div class="gmail_quote">

I apologise, I answered too soon thinking that I understood what you wrote.<br>
<br>
Walking the stack I get to a message in aFactorialTableComponent >><br>
addDecoration: aDecoration<br>
"Add aDecoration to the receivers decoration chain. Answer the added decoration."<br>
<br>
| previous current |<br>
previous := nil.<br>
current := self decoration.<br>
"etc.."<br>
I see that decoration returns nil and therefore "^ decoration contents"<br>
generates the error condition.<br>
I can't decipher what else is happening by going further back a couple of steps<br>
to the start message. The component was generated by following the example in<br>
