Hello, I am trying to create a pickerFieldCustom. I was able to make

In general: If you are following the SAIL recipe for custom pickers (forum.appian.com/.../SAIL_Recipes, notice that the apply() function is used over the rule!ucArrayPickerGetLabelForIdentifier rule in the selectedLabels parameter.

If you are having problems with your code, attach it to your post so others may assist you.

If I want to avoid sending it to a rule, how can I do that? This is what I have:

selectedLabels: if(
or(
rule!APN_isBlank(
ri!value
),
count(
ri!value
) = 0
),
null,
apply(
index(
_,
rule!Q_getEmployeeForPickerByID(
ri!value
).Name_Email_Division,
rule!Q_getEmployeeForPickerByID(
ri!value
).UserID,
ri!value
)
),
value: ri!value,
saveInto: {
ri!saveValueInto
}
)

ri!value is what's passed in to my expression. Name_Email_Division is the label that contains the UserID.

I created the rule and used this code. Now when I test the picker it leaves no label.

selectedLabels: if(
or(
rule!APN_isBlank(
ri!value
),
count(
ri!value
) = 0
),
null,
apply(rule!RULE_multipleEmployeeLabelForPicker(identifier: _, labels: rule!Q_getEmployeeForPickerByID(
ri!value
).Name_Email_Division, identifiers: rule!Q_getEmployeeForPickerByID(
ri!value
).UserID), ri!value
)
),

Ignore all the previous code. What I have now is pasted below. It will select one item but then it returns an error related to selectedLabel and value not being the same length:

= a!pickerFieldCustom(
label: ri!label,
instructions: ri!instructions,
required: ri!required,
requiredMessage: ri!requiredMessage,
readOnly: ri!readOnly,
disabled: ri!disabled,
maxSelections: if(
isnull(
ri!maxSelections
),
1,
ri!maxSelections
),
suggestFunction: rule!RULE_getEmployeeForPicker(
_,
if(
rule!APN_isBlank(
ri!numResultsReturned
),
20,
ri!numResultsReturned
)
),
selectedLabels: if(

rule!APN_isBlank(
ri!value
),
null,
apply(rule!RULE_multipleEmployeeLabelForPicker(identifier: _, labels: rule!Q_getEmployeeForPickerByID(
ri!value
).Name_Email_Division, identifiers: rule!Q_getEmployeeForPickerByID(
ri!value
).UserID), ri!value
)
),
value: ri!value,
saveInto: {ri!value,
ri!saveValueInto
},
refreshAfter: "KEYPRESS"
)

For anyone of concern I've figured out my issue. It had to do with my query rule not accepting multiples. It works now, thank you.
