Examples
The log command is helpful in printing out progress messages as the Flow goes into different paths as well as showing results of expressions. For increased visiblity, you can set the level to SEVERE.
<log message="User selected the record ${selectedRecordId}" level="SEVERE">Do note that some of the more complex kinds of variables, such as Files, do not have a particularly meaningful text representation and using them in the expressions may not be very useful. If you'd like to specifically inspect expression results, the logVar command may be more helpful as it also tells the type of the resulting variable.
You can also easily test conditional expressions. The expression will be displayed as either "true" or "false".
<log message="someMap has content: ${not empty someMap}" level="SEVERE">
