> Still trying to use NB annotations to declare a singleton action class, this is driving me nuts... I did some tests. Calling Actions.forID(x, y) twice in a row returns the same instance. Same for Utilities.actionsForPath(). Same in my app.  BUT, if I run the second call to Actions.forID(x,y) a few seconds later in my app (I trigger it manually with the mouse) then, *sometimes* (1/3?), I get a new instance ! Same problem for Utilities.actionsForPath(). Note that both calls are done on the EDT. I looked at the NB code on github, the underlying lookup mechanism in filesystem/RecognizeInstanceFiles.java is based on ProxyLookup, which uses lazy instanciation. So I assume that sometimes something happens differently here. But can not understand why... I noticed that Actions.forID() uses FileUtil.getFileObject(). Doc says "In environment with multiple contextual Lookups, the method may return different FileObject depending on what Lookup serves the executing thread." And
> recommends to use FileUtil.getSystemFileObject() to make sure to get a single instance. What is a "contextual lookup" here ? I guess I have to try recoding forID() with getSystemFileObject...

In my code an instance is first created using Actions.forId("jjazz", "myactionid")  I also want to use MyAction in a popup menu. I use Utilities.actionsForPath("Actions/popupmenu") to retrieve the actions before creating the popupmenu. But actionsForPath() creates a new instance of MyAction. Why ?    I'm pretty sure in other cases it reuses the initial instance. Tried to debug but it does not work inside actionsForPath() -don't know why... Any tip welcome, thanks.
