well i dont know if you need second-phase-init then you are likely doing something that is "context-sensitive" because this context is the only thing you are missing in the constructor really.
so when you move things around the context changes, so should the component reinit itself? -igor On 5/4/07, Jonathan Locke <[EMAIL PROTECTED]> wrote:
good question. re-adding dynamism seems like a fairly unusual use case (can you think of any good ones?) so i think the answer is probably no. it seems like if you have a component that dynamically does things on being re-added you could manage that case on your own. igor.vaynberg wrote: > > so is it a firstattach if you remove a component and then readd it at a > later time? > > -igor > > > On 5/4/07, Jonathan Locke <[EMAIL PROTECTED]> wrote: >> >> >> Although I do still think we should generally discourage two-phase >> construction, it is occasionally truly necessary and it seems like it >> might >> be nice to have a method up in Component that uses those component bits >> to >> return whether the component has been attached already.
