Hello,
i need to create two o more copy of a report where for each copy i need to change the value of a "label"
accordingly some rules from the final user. Currently I added a parameter to the report and i pass the desired value.
For example i need to put only the following text: "Copy for me", "Copy for XXX YYY", ecc...
and due the great quantity of data/processing time involved during the fill i need to wait for a long time for each fill.
Is possible to change the value without re-fill the entire report?
thank for you help
Stefano

Hi,
yes it is.... we do so when numbering our copies (e.g. Copy X of Y) withour regenerating the whole printout.
So try the way we do (and this is working fine for at least 3 years) :-)
- create a textfield where you later want to insert your copytext
- set the textfield expression to " " so just a space character
- make sure that the text you'll insert later will fit into the field (make it wide enough)
- set the anchorname-expression to something like "COPYFIELD" (perhaps you can also use the element-key attribute, this should be readable also in JasperPrint-Object (when we started it wasn't, that's why the way via the HyperLinkAnchorNameExpression)
- set the "RemoveLineWhenBlank" to FALSE (important!!!)
now if you have your JasperPrint you just need to parse that object and set the text .. see my method below.
