Hi BIRT specialists!
I have one question how not to display "NULL" value (as first) in
cascading parameters in BIRT?

Everytime I set it I receive NULL value as first entry.

Thank you for your help.

Best regards
Marcin Kierdelewicz

It is set to "is required" but fist position is allways empty with no
value (maybe it is something different than NULL in SQL"

Thank you for your help.

Marcin,

You need to set a default value if you do not want the first entry to
show blank.

Take a look at this simple report and notice the first one does have a
default value and the second does not.

Dear Jason,
thank you for you answer.
I can't relly use default value in my case because I need to hide
somehow empty value not from the first parameter in cascading only in
others and I don't know what value they have because they are based on
first parameter value.

With reference to your example I would like to hide first empty position
in prodcode parameter.
Is it possible to enter in default value any expression or function that
displays first entry instead of empty row maybe?
Could you help me with this, please?

Thank you very much. I am really impressed with your knowledge. Every
solution you give always works!

Best regards
Marcin Kierdelewicz
