Reporting test mode with field of type typeahead

Dear All,

We have one custom field set up as typeahead. That is one which refers to one object such as user, company, etc.

Referred object also has custom field itself.

We are trying to get one custom field from the referred object.

Would it be possible to confirm it is something which is supported by text mode? If yes, we would interested to understand how we should write text mode formula.

We have used below formulation which is incorrect as it leads to blank result. It was not possible to find any link which would provide us some hint and we turn to the community for help.

displayname=myfield2

textmode=true

valueexpression={DE:myfield1:parameterValues}.{DE:myfield2}

valueformat=HTML

Any help would be appreciated
