Well ... a perspective is entirely hidden from the user. So
perspectives don't really have user data associated with them. Do you
mean you want to have information from view1 in p1 available in view2 in
p2, when you switch from p1 to p2?

What is the best way to to have information from view1 in p1 available in view2 in
p2, when you switch from p1 to p2?

The scenario I have is there are two perspectives, the first one has a list, the user selects a row and click a button which programatically changes to perspective2 and is meant to show detailed information in a number of view about the row selected.

I've tried a selection provider, but view2 isn't loaded until the first time p2 is loaded.

Thanks

Hmmm, what about doing an getSite().getPage().findView("view1.id") from
your view2 code.

Assuming it's not null, you would be able to cast it to a view1 and
query view1 for it's current selections.

I have done this by getting handle to the SWT Display and using it's
setData(Object obj) method to store a bean. SWT doc indicates this
facility can be used to store arbitrary data. The second view in another
perspective can pull out a reference and even register as listener on
changes to the beans properties so you can update the second view.
