Hi Jeff,
thanks for the tip on compiler option; it does now work but...
I have added the -services compiler option to Flex Builder and have
-locale en_US -services
C:\lcds\tomcat\webapps\lcds-samples\WEB-INF\flex\services-config.xml
-context-root=/
on debugging, the destination for insync is not set and I managed to
load the database content once.
Now I have this problem: (it is related to the database connection now)
full listing:
'cds-consumer-insync-null' consumer set destination to 'insync'.
Configuration for destination='insync':

Do you know what I should do to solve that?

the -services option, or it is settable as a project option in flex
builder).

You can see exactly what XML the client gets by looking at the variable:

the client is seeing for that destination. I suspect insync is maybe
getting put in there but without a <properties><metadata><identity
name="foo"></metadata></properties> construct.

error initializing that destination on the server at startup. To
check on that possibility, make sure to check your server's logs for
errors and possibly add "Message.*" and "Service.*" targets to the
services-config.xml's logging section and set level="Debug" there to
get more info.
