Creating Collections from column

[plunavat]

Hello,

i need to create a collections variable from the fields.

I have a field called RollNo. when i place this field in detail band, it would display all records. say it displays 5 records with 23, 67, 45, 89 and 90

Now i want to create a variable "RollNoList" with type as collections such that it would have value  {23,67,45,89,90}. RollNoList would be dynamic and should have all roll no records.

(something like "sum" where the values are added automatically)

 

thanks in advance

Simply set the variable with increment type "none", calculation type "nothing" and with an expression like:

$V{RollNoList}.add(${fieldname} ? $V{RollNoList} : $V{RollNoList}

Perhaps there is a better way, but this works.

Cheers, Thomas.
