[jira] [Updated] (TAP5-2583) Extending expression language with
"default"-option
[ https://issues.apache.org/jira/browse/TAP5-2583?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Roman Mertyn updated TAP5-2583:
-------------------------------
Description:
Actually value of expression "user?.name" will by dropped if instance of user is null.
Any chance to extend this expression with default ( or alternative) value?
Suggestion:
${user?.name| 'Unknown user'} will be evaluated to user's name for existing user or "Unknown user" text elsewhere.
Same here:
${user?.group?.name| 'No Group or User'} will be evaluated to "'No Group or User" if user or user.getGroup() evaluates to NULL.
