Description

Currently, any properties defined in a script for ScriptedLookupService do not get added to the ScriptedLookupService dialog until the service is enabled. This defeats the purpose of scripted properties as some may be required, and enabling the service can instantly render it invalid.

It would be better if ScriptedLookupService worked like InvokeScriptedProcessor in the sense that the properties are queried when the ScriptedLookupService dialog is "saved"/"applied" by hitting the Apply button on the dialog. Then the properties will be added the next time the dialog is opened, and the correct validation can be performed.
