------------------------------------------------------------------
[~svimal2106] I just checked that getD() returns the path . Was this
intentional and guaranteed to be null in all cases?
If not, then we can use getT().getCompleteName if getT() is not null else
default to getPath()
was (Author: suma.shivaprasad):
[~svimal2106] Can you check if getT() is not null and use that first and if
null the database.toString()?
