Input to a Controller instance's caption should be limited to 30 characters

Current Situation

During registration of a Controller in the JOC Cockpit Registration view it is possible to specify a caption holding more than 30 characters. This throws the error

Caused by: oracle.jdbc.OracleDatabaseException: ORA-12899: value too large for column "ACCPJS"."INV_JS_INSTANCES"."TITLE" (actual: 31, maximum: 30)

Desired Behavior

• The JOC Cockpit Registration popup window should allow a caption with up to 30 characters only.
• The web service controller/register also should limit requests to 30 characters for the caption.
