Re: applescript parsing: list of record types

for one of my script commands specified in my sdef file, i've specified the direct parameter to be of type="my record type" list="yes" where "my record type" is defined in the sdef as a record-type element.

and if i turn i AEDebugReceives, i can see the list of records coming in. however, cocoa scripting complains that it can't make the list into a "my record type".

i've discovered that if i specify in my sdef to take a list of type="any", i can then get the data, but i get it as an aedesc, which i then have to parse myself. and the documentation in the script directory seen by the user is misleading.

have i encountered a (known) limitation of cocoa scripting? or perhaps a bug? is there perhaps another way to write my sdef so that i don't have to parse the sdef myself? or is there perhaps some method i can/should override in NSScriptCommand to properly handle this?

The only limitation I remember in this area (though I'm hardly an expert on the AppleScript <=> Cocoa side of things) is that you can't pass an arbitrary record from AppleScript to Cocoa without using type="any" because Cocoa has no way to map the record field names into strings for use a NSDictionary keys (remember, AppleScript uses four character codes, not strings). At least, I think that's the problem I ran into...


So, is your record type defined in your sdef file? Is the syntax of your sdef file correct?

You might be better asking on the applescript-implementors list (which I've copied on this reply); even though this is Cocoa related, you're still more likely I think to find help there than here. Of course, I might be wrong :-)

Kind regards,

Alastair.
