John,
If you want to construct an HTML tag and put it into your page, THE
place to do it is:
>>>onBeforeHtmlOutput(..)<<< of the Display Field concerned using
>>>((CSpDiplayField)event.getSource()).setHtmlText(....)<<<
If you do setValue in onBeforeDisplay(..), ND will convert your
string so that in the final HTML page, you get to see exactly what you set
and if you look at the Html source you see & stuff.
I would prefer to construct the string in the onBeforeDisplayEvent
of the page and keep the value in an Instance variable for use in
displayField_onBeforeHtmlOutput(..)
