Pinned topic Best way to implement access control rules In IBM Case Manager Client
What approaches are there to implement field level access control rules -- where the rules vary by user user role -- using the IBM Case Manager client and its set up of widgets ? Are there any out of the box solutions ? If that is not the case, which solutions involve the least amount of custom coding ?

I have implemented something similar in Work Details pages by doing the following high level steps (ICM 5.1.1):
- Disable Send Case Information broadcast event in Command widget
- Wire a Script Adaptor between the Command and Properties widget using the Send Case Info events
- In the script Adaptor do the following:
- Get the Roles the current user belongs to using the BPM REST API
- Determine what field level permissions this user has based upon their Roles.
- For Prototype you can hard code the logic in the Script Adaptor
- In Production you might want to develop a custom REST API and have the Script Adaptor call it. The REST API can then get the field configuration data from a DB, etc.
- Amend the payload to disable / hide certain fields based upon the users Role
- payload.caseInfo.caseData.XYZ_MyField.isHidden = true <=== Hidden
- payload.caseInfo.caseData.XYZ_MyField.required = true <=== Required
- payload.caseInfo.caseData.XYZ_MyField.updatability = "readonly" <=== Read Only
- Take a look at the Infocenter for more details on the payload structure or use console.log (payload); to dump out a working payload to Firebug
- Return the amended payload to the Properties widget
From your description above where you say create / update / delete values, I'm guessing that you are talking about arrays of values here. I haven't tried this technique with arrays but would be interested to know if you get it working. I wonder if you can use the technique on individual elements, or whether it only works at entire field level?
I don't really like using the built-in array control anyway as it is not very functional and does not work where you need to have multiple array fields linked together (i.e. FirstNameArray, SurnameArray, etc.). In these scenarios I normally hide the arrays using the "isHidden" property and then use a custom widget to just display the required array fields. You can then pass the updated values back to the fields in the Properties widget by using the UpdateDependentProperties event / payload. This has got to be easier than thinking about totally re-writing the Properties widget.
Also, have you considered using Forms to provide this sort of functionality.
