Configuring a User Picker
Objective
You want to add a user picker to a custom UI and need to configure the picker to:
• Search only for objects of certain type(s)
• Search only for objects in certain container(s)
• Display certain search critieria input fields
• Display certain attributes of the objects in the search results table
Background
The user picker is used when you have a requirement to select specific user(s) depending upon certain criteria and use them in your application. Typical use case could be that you may want to find parts which are created by certain user. In this case you can have a user picker and then through this you can select the user and pass it on to the search criteria to perform search for parts.
Scope/Applicability/Assumptions
It is assumed that your <MyPage>.jsp file in which you are putting tag includes “/netmarkets/jsp/begin.jspf” or “/netmarkets/jsp/beginPopuf.jspf” file and “/netmarkets/jsp/end.jspf” files.
Intended Outcome
You should see a text box and Find icon along with the specified label after using the tag for user picker. After clicking the Find icon, a user picker will be launched.
On clicking the Find… button you should see a user picker.
Solution
Use the User Picker Common Component in your JSP file to include User Picker in your application.
Prerequisite knowledge
To achieve this objective, you need to have an understanding of the following:
• Basic development involving JSP, JavaScript, Custom taglibs
• The management of resource file customizations.
• Windchill xconfmanager concepts

var displayAttr = eval("myJSONObjects[i].fullName");
