You are seeing transactions at work. Your DTML Method _is_ being processed,
only an exception caused the publishing process to stop, roll back the
transaction, and return the error message to you.
DTML is not a linear language like ASP, it is not processed one line at a time
and bails out at the first error. DTML is parsed into an object tree when
entered, and this tree it then later on asked to render itself. An exception
in this tree will propagate down to the publishing level, and then turned into
an error response. So DTML is, like Python and Java, object oriented and
If you want to see how far a page gets, try using <dtml-try> blocks around
parts of your code. You can then catch the exception higher in the object
tree, and generate your own messages in reaction to this.
