This is our list of very best practices. Helps a lot in daily works.

- Always be consistent in naming and follow our naming conventions! Process variables of same semantics are named consistent in all models !

- Always check incoming expression parameters for being NULL or empty !

- Always access CDTs or dictionaries using the index() function !

- Always be consistent in type of returned data. cast(type!YOUR_CDT_TYPE, null) is fine !

- When you get data from queryEntity(), queryRecord() or queryProcessAnalytics(), print it to screen, have a look at it and validate it! Then use it.

- Always pass arguments by keyword. See forum.appian.com/.../Expressions.html
