Value of State field not populating on widget

[nksrapn]

I am working on a widget, where I am populating some fields from asmt_assessment_instance table, I have created variables like this

var fields1 = 'task_id.number,sys_created_on,state,due_date,u_survey_type';

    var fields2 = 'task_id.number,sys_created_on,state,due_date,u_survey_type,taken_on';

    var fields3 = 'task_id.number,sys_created_on,state,u_survey_type,taken_on';

    The value of state field is coming blank in widget, how I can solve this??
