Check with Len. It'll affect him more than anything, so if he's ok with it JFDI ;-)
BTW, move to 4.2.1: this isn't strictly necessary for 4.2, so just in case you don't find the time.
I should get it done over the weekend (next 2 to 3 days). It is important for the training materials.
However, I'll leave the more_action one in place as well. It can be removed when the time is right.
OK. Create a separate JIRA for removing the old one and assign it to Len. Once he's migrated over to your new one he can get rid of it.
The new custom_action quickstart is now checked in. It demonstrates multiple ways to create a customizable/configurable action via the ConfigTree and BeanConfiguredAction. It also demonstrates how to make both a Sync and ASync calls via the ServiceInvoker from a J2SE/main method type of client.
You can find it here:
The ServiceInvoker is illustrated here:
