Multiselect field: allow multiple default values from script

[bugy]

At the moment, script server supports default value, which can be initialized by a script, e.g.
"default": { "script": "echo 123" }
will set default to 123

However, for a multiselect list, it will work only for a single value.
It should be possible to set multiple default values from script, if it's a multiselect parameter.
All values should newline separated

Hi @bugy , please let me know how to use this feature?

Hi @sbalakrishna, if a script returns new-line separated values, they will be treated as separate values, in case of a multiselect parameter type
