Hi, Moray
[1] You might try deleting the class NSApplication from the suite.
It declares (redundantly) ordered documents, but not ordered windows.
[2] Try changing all your commands' class codes (DEMO, DISC. OPCO) to
the suite's code, DATP.
That's the default in Suite Modeler, but it doesn't flag deviations as
errors.
[3] You have some other Apple Event Code assignments that seem
trouble-prone.
code ext. name type
pnam URL NSObject pnam generally associates with "name" and
NSString
opco open con... OpenConnection all
lower-case* disc Disconnect Disconnect all lower-case*
*Apple reserves the space of all-lower-case codes. However, we can
re-use them. Your 'capp' and 'docu' codes
seem fine in that regard. I haven't seen documentation from Apple that
clarifies this, though.
See
/Developer/SDKs/MacOSX10.3.0.sdk/Developer/Headers/FlatCarbon/
AERegistry.h
for codes we're to re-use.
There, we find

/* Classes */

cURL = 'url ',
That may prove useful in your OpenConnection command's URL argument.
(Can't tell -- it' type is NSObject.)
[4] All of your command handlers are
handleDemonstrateScriptCommand:
Put a break point in the handler.
I expect that your DoSQL and Disconnect commands BOTH invoke the
handler (fine from the outside -- they both have no arguments.)
However, OpenConnection has an argument.

For my own information,
[5] I'm surprised that the Java command handlers have Objective-C-like
colons
handleDemonstrateScriptCommand:
I just checked the Java Sketch example, and its suite has no supported
commands.
I've not fooled with scripting Cocoa/Java.
