Re: [orchestra] Conversation Timeouts (was changed scope configuration)

[simon <si...@chello.at>]

Currently the config for a scope (from which a conversation inherits its
properties) looks like this:
  <bean class=".......orchestra.spring.SpringConversationScope>
    <property name="timeout" value="30"/>
  </bean>

If no timeout property is present, then no timeout applies.
Otherwise, the specified timeout applies.

It would be easy to instead say that if no timeout property is present
then the default applies. But how do you suggest a user then selects "no
timeout"?

Option 1:
A magic value like "-1"? Possible, but obscure I think.

Option 2:
To make the timeout property a string, which can contain either "no" or
a numeric value. This is just like the first option, except that a magic
word is used instead of a magic number.

Option 3: 
Another boolean property, "hasTimeout" which can be set to false? Also
possible, but it seems clumsy.

This configuration awkwardness was the main reason I changed the old
behaviour of having a default timeout of 30 mins - I couldn't see an
elegant way to have that *and* an elegant way for the user to disable
timeouts completely.

Are there any other alternatives?

BTW, When Mario originally said "the user must configure a timeout", he
meant that they must configure a timeout if they want one because a
timeout is no longer enabled by default.

Simon
