hiding an element in pdf output [message #181673]

Hi!
I have a problem with pdf output using birt (version 2.0.1). I made a
report with some tables and I wanted to conditionally hide them, so I set
Visibility param in Property Editor of an element to something like
"Total.count(row.DATA_WPL != null) == 0" where DATA_WPL is a column from
defined by DataSet. It works almost as I expected: table is hidden when no
data is returned by DataSet, but it seems like birt is reserving space
form hidden element and shows blank space in place of hidden table. So
other items are placed lower than they should be, not immediatelly after
previous visible item. Furthermore, when hidden table would span on 2
pages (it starts at the end of one page ang ends on the next page) and I
wanted a page break befeore next element - that leads to a blank page in
the pdf output, because as I mentioned birt reserves space for a hidden
table.
Do you experience similar behaviour ? What should I do in order to
completely hide an element in report ?

I think I found a solution, I've tried that earlier, but somehow it didn't
work. For a table that I want to hide I define table.onCreate method to
sth like:
if (hide_table_condition) {
this.getStyle().display = "none";
} else {
this.getStyle().display = "block";
}
where hide_table_condition is the same as previously used in Visibility
param in the Property Editor of the same table. Is it correct ? I have
many tables (subreport) in my report nested inside another table
(masterreport). Anybody knows of some "magic" consequences of using such a
script ?

Looks like a good use of scripting.
