generic ref from trans to trans object

[Simon Oberhammer]

hi group :)
the subject says it all. when I try to set a generic-reference-field
of a transient object to another transient object, I get this error
msg:

{{{
get:/ helma.scripting.ScriptingException: Wrapped
java.lang.RuntimeException: Object is transient, can't derive
persistent ID for Relation [dgf.Tag].target_id -> tag_f_target_id
}}}

the message makes it sound intentional, though I don't understand why
this doesn't.

Minimal test case with demo app [1] would be:

{{{
var image = new Image();
var tag = new Tag();
image.tags.add(tag); // error...
}}}

we're using more and more generic refs - so at least understanding why
this doesn't / can't work would be helpful.

bye
simon

I guess the message means "I haven't bothered to implement this yet".
I'll have a look at it. Maybe it's enought to just bypass the whole
generic reference code for transient objects.

Hi Simon,

I think this should work now in Svn trunk. Please let me know if it
doesn't, and thanks for reporting it.
