Bug: Script List param defaults

[wmoore]

If a List parameter has a list as a default value, this is ignored by the clients and they simply use the first item in the list as a default.

See ​https://github.com/openmicroscopy/openmicroscopy/issues/2306
for screenshots and example script.

Test script:

import omero
import omero.scripts as scripts

from omero.rtypes import rlong as _
from omero.rtypes import unwrap

c = scripts.client("test", scripts.List(
    "IDs", default=[_(1), _(2)]).ofType(_(0)))

print unwrap(c.getInput("IDs"))

Updated comment points to my test script (above) being invalid. Instead of a scripts.List, this problem involves a scripts.String.

[wmoore]

Josh - in fact, your script does expose a bug in the clients' UI if the default value is a list, so it is perfectly valid for this ticket. There was no other bug reported by ​https://github.com/openmicroscopy/openmicroscopy/issues/2306 - Just confusion about how the Data_Type parameter is being populated in the clients.
Since we have no example scripts that use a list as a default value, this is quite low priority (although I guess there's a potential use-case for this).

Thanks for deciphering that. Pushing then.

[wmoore]

Pushing until this becomes a higher priority.

Fair enough. But I don't know what should be done here, so taking my name off.
