CastInvalid error when using Encrypted Text Field

Thanks for answering my post.

I created a CDT just to the personal information that I want encrypted.  For each of the encrypted fields, they are set to Encrypted Text.

I rewrote my interface to use the new CDT and used the Encrypted Text field.  Now I receive the following error message when I type in something to my fields.

Expression evaluation error [evaluation ID = 37dd5:9dfec] in rule 'pmso_createorupdatespeakerpersonalinfo' at function a!encryptedTextField [line 51]: An error occurred while executing a save: java.lang.IllegalArgumentException: Invalid index: Cannot index property 'speakerCitizenshipCountry' into type List of Null

Here is the code for the encryptedTextField.  All of my fields are set the same and give the same error message.

a!sideBySideItem(
            item: a!encryptedTextField(
              label: "Country of Citizenship",
              labelPosition: "ABOVE",
              placeholder: "-- Please enter your country of citizenship --",
              value: local!speakerPrivateInformation.speakerCitizenshipCountry,
              saveInto: local!speakerPrivateInformation.speakerCitizenshipCountry
            )

How are you defining the local variable for `local!speakerPrivateInformation`? You have to make sure that local variable is strongly typed by setting it to an initial value. There are restrictions around how you use encrypted text because you can't cast between it and other types, so you have to be explicit on how you define the variables that are used.

In the interface

local!speakerPrivateInformation: rule!PMSO_getSpeakerPrivateInformationbySpeakerId(local!speakerRecord['recordType[PMSO Speaker.fields.speakerId']),

in the expression rule..  It returns null as of now, I have no test data.  I need to encrypt the fields, so I need the create.  You have to excuse me, I have only been using Appian for about 5 months.  How would I cast or type the record or variable?

a!localVariables(
  local!data: a!queryEntity(
    entity: cons!PMSO_speakerPrivateInformation,
    query: a!query(
      filter: a!queryFilter(
        field: "speakerId",
        operator: "=",
        value: ri!speakerId
      ),
      pagingInfo: a!pagingInfo(1, - 1)
    ),
    
  ),
  if(
    count(local!data.data) > 0,
    local!data.data[1],
    null
  )
)

Try something like this:

a!localVariables(
  local!data: a!queryEntity(
    entity: cons!PMSO_speakerPrivateInformation,
    query: a!query(
      filter: a!queryFilter(
        field: "speakerId",
        operator: "=",
        value: ri!speakerId
      ),
      pagingInfo: a!pagingInfo(1, 1)
    ),
  ).data,
  cast(
    'type!PMSO_Speaker', /* I'm not sure what this is called, but just use your CDT */
    local!data
  )
)

Thank you, but I am still getting an error.  

Details: CastInvalidCould not cast from PMSO_speakerPrivateInfo to Number (Integer). Details: CastInvalid

My expression rule.

a!localVariables(
  local!data: a!queryEntity(
    entity: cons!PMSO_speakerPrivateInformation,
    query: a!query(
      filter: a!queryFilter(
        field: "speakerId",
        operator: "=",
        value: ri!speakerId
      ),
      pagingInfo: a!pagingInfo(1, - 1)
    ),
    
  ).data,
  cast(
    'type!{urn:com:appian:types:PMSO}PMSO_speakerPrivateInfo'(),
    local!data
  )
)

The error message references line 14

Could you print the variable local!data? I suposse it contains the same fields that you have in the type PMSO_speakerPrivateInfo

The data is null.  There is no data in the table.  This would also be true for the first time we are adding the personal data for a speaker.

Remove parenthesis when casting

a!localVariables(
  local!data: a!queryEntity(
    entity: cons!PMSO_speakerPrivateInformation,
    query: a!query(
      filter: a!queryFilter(
        field: "speakerId",
        operator: "=",
        value: ri!speakerId
      ),
      pagingInfo: a!pagingInfo(1, - 1)
    ),
    
  ).data,
  cast(
    'type!{urn:com:appian:types:PMSO}PMSO_speakerPrivateInfo',
    local!data
  )
)

Now I am getting this error message.

Expression evaluation error: Syntax error. Details: Expression evaluation error at function a!localVariables parameter 2 [line 14]: Unexpected empty parentheses.
