reusing interface

Question

Hi Team, 
 I have 2 interfaces, one which hold only the calender icon and other one which formats the date. 
 1st interface AB_icon 
 a!richTextDisplayField( value: { a!richTextIcon(icon: "calendar-o", color: "SECONDARY"), } ) 
 2nd interface which formats the date AB_formatdate 
 In the main interface, for one of the field I used both the interfece( my requirement is displaying the calender icon and the formatted date) 
 rule!FST_c_readOnlyFieldDisplay( fieldName: "t Date", value: { rule!FST_c_dateWithIcon() & rule!FST_exp_formatDate( datetime: ri!record[], showtime: false ), 
 But the value is not getting displayed, instead the below is displayed.

Can someone please help here

I think you are trying to show a richTextDisplayField in a textField. 
 What is the use of FST_c_readOnlyFieldDisplay()

{
 a!columnsLayout(
 columns: {
 a!columnLayout(
 contents: {
 a!richTextDisplayField(
 labelPosition: "COLLAPSED",
 value: {
 a!richTextIcon(
 icon: "calendar" 
 ),
 a!richTextItem(
 text:todate(now())
 )
 }
 )
 }
 )
 }
 )
}

a!localVariables( local!date:today(), a!richTextDisplayField( value: {a!richTextIcon( icon: "calendar", )," ", a!richTextItem( text: local!date )} ) )

Since nobody else mentioned this specifically - "&" is the string concatenation operator. When you use it between the two other elements, it causes Appian to concatenate the contents of these into a string - that doesn't concatenate the output into a string, but rather concatenates the component code into a string - hence what you have in your original screenshot.
