Jesse, I stepped away from the computer for a bit, and I had just now
submitted the JIRA before updating this conversation.
https://issues.apache.org/jira/browse/TAPESTRY-1477
I am happy to know it is something that happens on purpose, and for
developmental issues. I would hate to have my DAO's get called 3
times in production though, so if similar ensurances are left in, I
hope there would be a way to turn it off via a flag, etc.
Does this "ensuring" feature only apply to IF components, or to others
as well? (i.e. are expressions for other components being evaluated
multiple times?) I have one dynamic form component that can make use
of up to 40 other core components based on multiple if/else
components.
I also feel assured now that this isn't some ill procedure that would
potentially break something down the line.
