Tips and Traps

From Plex-XML

Group model synchronization of new function

Always synchronize your newly developed functions with your Plex group model before first use. This makes sure they are getting a final surrogate number. We need the Plex surrogate number as an unique identifier within the formats of Plex-XML.

Parameters within messages

Never use fields of Plex array variables as parameters in messages. It may cause a crash of Plex, when generating code. Instead move them to a local single variable and map those fields.

Plex inheritance

• If an object is not real, then the inheritance engine skips it

• All objects in a standard layer should be real

• Altering the sequence of an "is a" triples lets you re sequence the inheritance path.
