[Is it possible to hide and show only some elements of a band based on some condition?]

My need is to show some records based on some status value which can have 3 vales a ,b or c

Now if c status has no records i need to show records not found. Same goes with a and b.

how can this be done?

[In Ireport if we pass map as a parameter from java to ireport how to access map values based on key of ireport field]

From java code I pass a parameter to ireport like this

fillReportToFile(sourceFilename, map, beanColDataSource1);

where map is something like this

AFG, [1, 2] AZE, [1, 1] BAN, [0, 1]

where key is country_name and the list are values . Now I need to access this in Ireport with key as country_name I tried following in ireport,

$P{$F{COUNTRY_NAME}}.get( 1 );

but it gives parse errors.

Can anyone suggest me some way of doing this?
