Another way of what I want. 1 Detail band, split tipe I used - Prevent or Immediate, FreeLayout.
All elements have position type - Float.
DataSource - JSON.
When the report is not fit to page 1, I need bottommost table (partial payments) and a pair of static texts to appears in page 2.
When in the middle part of the report any field not stretched, result looks like that (right result):
When any fields of middle block (purpose of payment, for example) stretching, bottommost table disappears. And it doesn't appears on page 2.
When I have 2 or more records in signatures table, partial payments table appears on page 2, that's correct.
What can I do to print all the report items in any case? I mean partial payments table and 2 static texts in case 2.
