             Summary: [DMN Designer] Default cell symbols
                 Key: DROOLS-2750
                 URL: https://issues.jboss.org/browse/DROOLS-2750
             Project: Drools
          Issue Type: Epic
          Components: DMN Editor
    Affects Versions: 7.9.0.Final
            Reporter: Jozef Marko
            Assignee: Michael Anstis


As a citizen developer, I want to build my decision logic with as small effort as possible. Especially I want to build the *valid* expressions with minimal interaction with the designer. For this reason the designer should fill in default values/symbols into cells where possible. This should help with DMN designer getting started experience.

In this epic we should discuss where is possible to fill some default values/symbols into expression cells.

h3. Context
I think no appropriate default value exists. Maybe with exception of the last row?

h3. Literal Expressions
My proposal would be:
- empty cell, if it is valid value for literal expression cell, if not
- value according to the column data type, 0 for number, today for date ...

h3. Decision table
- symbol *-* due to trisotext samples

h3. Function
Really not sure

h3. Relation
Really not sure

h3. Invocation
Really not sure

[~manstis] [~tirelli] [~tari_manga] could you please put your thoughts into comments? I filed this epic to follow agile process. Not saying something from description will happen. However if we will agree on some default values we can then file separate tasks for this epic. I f we agree it is not good idea, we will close the epic.
