Here is what I can tell.<br>
<br>
You are using Seaside. Somewhere in the page you are using a<br>
TreeReportColumn, and when you try to display the page, it is<br>
expecting a block with one argument (that is why it sent #value:) but<br>
got a block with a different number of arguments. If I were debugging<br>
this, I would look at that block because probably it is something you<br>
wrote. When you see it, you'll probably say "Oh, sure, that block<br>
should take an argument", though perhaps you will say "Why should<br>
*that* block take an argument?" but in either case, it will probably<br>
be a block that you wrote.<br>
<br>
Note that there is no class "Block", what we call a block when we are<br>
looking at a Smalltalk metod is really an instance of class<br>
BlockClosure.<br>
