[switchyard-issues] [JBoss JIRA] (SWITCHYARD-769) Simplify context access in mapping expressions

David Ward created SWITCHYARD-769: ------------------------------------- Summary: Simplify context access in mapping expressions Key: SWITCHYARD-769 URL: https://issues.jboss.org/browse/SWITCHYARD-769 Project: SwitchYard Issue Type: Enhancement Components: component-rules Affects Versions: 0.5 Reporter: David Ward Assignee: David Ward Priority: Minor Fix For: 0.5 The work done in SWITCHYARD-714 included the ability to use MVEL expressions to set rules and bpm variables. Inside the expressions, pre-set variables were called exchange, message and context, as well as context_in (same as context), context_out and context_exchange. These last names were there so that map access to the context from an expression would know which Scope to use. This is confusing and messy. Instead, context_in, context_out and context_exchange should all be removed, and just leave context, message and exchange. Map access to the context in an mvel expression should default to Scope.IN, but add an additional attribute to override that to Scope.OUT or Scope.EXCHANGE. See "contextScope" below: <mapping expression="context['foobar']" variable="foobar"/> same as <mapping expression="context['foobar']" variable="foobar" contextScope="IN"/> same as @Mapping(expression="context['foobar']", variable="foobar") same as @Mapping(expression="context['foobar']", variable="foobar", contextScope=Scope.IN) -- This message is automatically generated by JIRA.
