Thank you Mark S.!
I believe I understand now.
The widgets within the body of the $button widget happen as part of the
button definition only - nothing actually happens until the button is
pressed. Since the tiddler has not yet been created, the tiddler
$:/temp/create has not been created and therefore the new title is not
available in this context.
When the button is pressed, the action-createtiddler is executed as
defined, thus creating the new tiddler and saving the actual title in
$:/temp/create as requested.
Once the button has finished doing its job, the actions in the actions
attribute are executed. At this point the new title is available for the
$fieldmangler widget to access, and the tm-remove-tag message can work as
expected.
Pardon my detailed explanation, but I needed to work through it and thought
it might be helpful for others.
It makes total sense to me now. I just wish I was more comfortable with all
the subtleties of widgets, macros and messages. Sometimes I get totally
lost when trying to do something very simple!
Thank you again for taking the time to help me.
