How to put user picker in table builder

[hmungekar]

I tried doing it by using data utility but i am getting runtime exception "callback function is either not defined or there is error in it.unable to set null reference"

I used a data utility to add a user picker to my builder. I had to create a HashMap to contain all of the component properties that would otherwise be in the JCA tags.

HashMap<String,String> map = new HashMap<String,String>();

map.put("pickerId", "userPickerId");

map.put("hiddenId", "userId");

map.put("componentId", "userCompPickerId");

map.put("objectType", "wt.org.WTUser");

map.put("pickedAttributes", "fullName,name");

map.put("defaultValue", displayValue);

map.put("defaultHiddenValue", keyValue);

map.put("readOnlyPickerTextBox", "true");

map.put("pickerCallback", "userPickerCallBack");

map.put("showRoles", "false");

map.put("showSuggestion", "false");

map.put("suggestServiceKey", "userPicker");

map.put("multiSelect", "false");

PickerInputComponent pic = new PickerInputComponent("My User",displayValue, map);

pic.setColumnName(component_id);

pic.setRequired(AttributeDataUtilityHelper.isInputRequired(mc));

return pic;

We have a custom callback and such, but this works.

Object localObject = null;

if (mc.getRawValue() != null)

{

localObject = mc.getRawValue();

} else

{

localObject = "";

}

PickerInputComponent pic = new PickerInputComponent("My User",localObject.toString(), defaultProps);

pic.setColumnName(component_id);

pic.setRequired(AttributeDataUtilityHelper.isInputRequired(mc));

return pic;

}

}

Above data utility code I have written for user picker but when I seaech for user and click ok,I get exception as shown below.It means that I need to write a call back function.

I created a callback function in a .js file that is included in the .jsp for the action.

function userPickerCallback(objects, pickerID, attr, displayFieldId) {

var pickedObjs = objects.pickedObject;

if (pickedObjs != null) {

var updateHiddenField = document.getElementsByName(pickerID)[0];

var updateDisplayField;

var fields = document.getElementsByTagName("input");

for (p=0;p<fields.length; p++) {

var currInput = fields[p];

if (currInput.name.indexOf("userPickerId")>-1

&& currInput.name.indexOf("textbox___old")<0) {

updateDisplayField = currInput;

}

}

for (var i = 0; i < pickedObjs.length; i++) {

if (pickedObjs[i] != null) {

var userOid = pickedObjs[i].oid;

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

updateHiddenField.value=userOid;

updateDisplayField.value=displayAttr;

}

}

}

}

I wrote the above mention callback function in custom.js and validate.js file but still it is throwing the same error.
