Description

I need a lazy lifecycle strategy within Pico, as in one that will start a component only once it is required. Currently container.start() will eagerly instantiate lifecycled components before they are actually needed. I'd like to intercept when components are instantiated and start them before they are used.

Take a look again Mark.

See http://fisheye.codehaus.org/changelog/picocontainer/?cs=5533

You'll have to extend DefaultPicoContainer to make it work, but it should be what you want.

Found a problem with the current solution: an ISE is thrown when the container is disposed if the component hasn't been instantiated. {{PICO-355-test4.patch}} demonstrates the problem.
