[jboss-jira] [JBoss JIRA] (DROOLS-2750) [DMN Designer] Default cell symbols

[Edson Tirelli (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-2750?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13607862#comment-13607862 ] 

Edson Tirelli commented on DROOLS-2750:
---------------------------------------

For input columns in decision tables, we can consider auto-filling the dash ("-") symbol as the default value, but for every other type of boxed expression, I don't think there is any sensible default. It will have to be a blank (empty) cell.

> 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.
