@Bob – however, if you group an MSO with buttons inside, the targets (object states) in the buttons are wiped out. Un-group does not bring them back.

At least that will happen in InDesign CS5.5 v7.5.3.

Arg!

And: if you copy/paste a button on the page (not inside an MSO) the pasted button will loose its target, if the target is an object state.

@Bob – sorry, Bob. I'll try to explain again:

Say we have one MSO with buttons inside and and a plain rectangle on the page:
the moment you group the MSO with the rectangle, the button will loose its target, if the target is an object state (of the same MSO).

That's my experience with InDesign CS5.5.

Ah! One thing left:
what will happen if you do not copy/paste an MSO but duplicate (alt +  drag) an MSO with buttons inside?

See the following movie (hope the link will work. It's my first time with dropbox…):

Have fun!

@Bob – it seems it is the only way to get something like a button control from one MSO to another.
I stumbled over this just today so I had no time for testing.

So duplicating an MSO seems to be an option…

The example you see in the movie is a folio with PNG output saved as v20. Version 24 in this configuration is also doing fine.

I think we have to explore the new possibilities this will give us.
Though, I'm a little uneasy, because we leave the targets of the buttons inside the duplicated MSO in a very strange state:

Uwe

Nevertheless, it could be an option for Single Issue Apps, because the folio is baked together with the app and could not change in a future version.

Further tests will follow…

And I'm looking for a way to address the target of a button inside a duplicated MSO directly by scripting, so that the target can be changed to quite another arbitrary MSO on the page without breaking the "feature".

I think this is a very good example for exploiting something like a bug or a not programmatically finished feature… :-)

Uwe

P.S: Maybe someone, you?, should move that whole thread over to the DPS Forum?

A first test with "Preview On Device" is showing that the PNG folio is working as expected!
(iPad 3).

Uwe

By duplicating the one MSO from page 1 to page 2 with alt + drag, this seems possible now…
The target of the button inside the duplicated MSO of page 2 stays the same.

It points to the MSO on page 1!
Watch the second movie where I can proof this with the Content Viewer on my Mac:

At first  you see page 1 of the article.
Then I switch over (down) to page 2.
Click the yellow button on the single MSO on that page (that switches the MSO on page 1 to state 2).
Then I switch back to page 1 (up), where the state of the one MSO has changed from state 1 to state 2.

I can already confirm that this is also working with the Content Viewer on the iPad.

Uwe

Me too…

But as I already said, if we can bake that feature into a Single Issue App, 
possibly it will never break…

(And Now for Something Completely Different ;-) )

Until, of course,
I have to replace contents and therefore the app for a brand new version…
