<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>Hi All</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>I think this must be a fairly standard issue to
tackle so hopefully someone will know the best approach.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>A bit of background first:</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'> I have an 'application' (a software
radio) that consists of a number of morphs, well at least components that wrap
a morph. To create a running application the appropriate components are
instantiated within say one of more alignment morphs. The components are wired
up using connectors. On connection a simple protocol executes across the
connection so each end can discover the capabilities of the other end. All the interaction
by the user is conducted against the appropriate component, some might be
frequency displays where the digits can be scrolled, others just button bars or
sliders etc. Administration is done by starting a seaside session on the admin
component. At present this shows a small admin morph in the world and this must
be connected manually to the component to administer, the protocol exchange then
occurs (but for admin functions this time) and the admin page for that
component is dynamically generated.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>So far so good. There can be a lot of different
configurations for doing different types of work. So the idea is simple, the
user builds a number of radios with different components. Without any
programming they use the direct manipulation interface to change colour, layout
policy, move components around and add any of their own (like a clock for
instance). In other words they build their radio(s) to their exact requirements.
To remove the clutter of connectors they are simply made transparent. I would
also like to ship with a number of pre-built examples.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>Finally, to the question.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>What is the best way to save and restore these
applications with all their associated state.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>1. I don't want to generate them with code (unless
code can be generated automatically and anyway that does deal with state) as
that would seem to defeat the object. </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>2. I don't want to rely on the image being the
container as that's inappropriate in many cases. </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>3. I think one answer possibly lies in the various
menu options that save a morph (the top level container of the app presumably) or
save a project. I have been unable to get any of these to work. Project seems
the most hopeful but objects to the fact some components use Opera and if the
other end of the link is not there an exception is thrown. Also I think a
project is the world and I just want a part of the world. </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>4. Do I have to use something like Magma to store the
entire object tree. </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>5. Or ... is there a way to tap into the image
serialisation to just store a specific tree. </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>6. I even tried a card stack. I could seem to get the
components to stick to a card but every time I switched cards the connectors got
disconnected. Not quite sure where I was going with that one. </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>Thanks to anyone who has the energy to read this long
post and even more to anyone who knows a way that works for them.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
