Hello everyone,
I am having some error messages when I am trying to set values to some fields 
in a PDF form. Many of the values are set fine but then I get these error for 
some fields.
 
java.lang.NullPointerExceptionpdmodel.interactive.form.PDAppearance.calculateFontSize
pdmodel.interactive.form.PDAppearance.setAppearanceValue

I noticed that the fields that get updated have font size = 12 and font type 
Helvetica. If I manually go to the file and change the fields that are not 
being updated to size =12, font type Helvetica then it works!!
I can not have all the fields be the same size and font type. Is there a way to 
get around this? and why do I have this problem in first place?
Any help would be appreciated. Thanks!
