The result of the On value change condition is based not on the data value itself, but on whether the data
has changed from one data page to another.
The On value change condition has two parameters:
l As with all other conditions, the first parameter is mandatory and it represents the data region to
monitor. Depending on the emulation, the selection can be a block of data, a single field or an
advanced PlanetPress Talk statement.
l All Text/PDF emulations: Allow the selection of a block of data.
l XML/Database: Allow the selection of a single field.
l Any emulation: Allow any valid PlanetPress Talk expression.
l The second parameter allows the user to specify an existing condition or a PlanetPress Talk
expression that controls whether the On value change condition should be evaluated or not. This
option is useful, for instance, to monitor the contents of an Address block, but only when the string
“Page 1 of” is found on the data page as well (otherwise, the address block would be considered
as “changed” on datapage 2 if it is not repeated in the data stream).
Page based
A page-based global condition compares the page number of the current data page with a page number
you define, or compares the position of the data page in a set sequence of data pages with a page posi-
tion you define.
Type of test: Select the type of test you want the condition to perform. There are five types of tests:
On page, Less than, Greater than, Less than or equal to, Greater than or equal to. For example, if you
know the first data page is always a banner page, you might want to suppress printing it by creating a
condition to test for a page number equal to 1 (an On page test) and associating that condition with the
first page of the document. Or, you might want to insert a separator page before the first page of every
sequence of 9 data pages. In this case, you create a condition to test for the data page being the first in a
sequence of 9, and then create a separator page that prints only if the condition is True.
Page number: Enter the page number or use the spin buttons to adjust the value. This is either the
page number of the data page, or the position of the data page within a set sequence of data pages. In
the latter case, you select Of, and use Sequence to define the number of pages in the sequence.
Of: Select to indicate the test is on a sequence of data pages.
Sequence: Enter the number of data pages in the sequence, or use the spin buttons to adjust the value.
Advanced
An advanced global condition is a condition that you define using PlanetPress Talk expressions. You can
include existing global conditions in an advanced condition.
Advanced condition: Enter the PlanetPress Talk expression that defines the test you want the con-
dition to perform.
4. In the Override mode box, select how you want PlanetPress Design to evaluate the condition during the design
phase.
Data: Select to have the value of the condition depend on the contents of the sample data file. This in effect removes
any override, and results in the condition behaving as it will at runtime.
True: Select to have the value of the condition always equal to True.
False: Select to have the value of the condition always equal to False.
5. If necessary, add PlanetPress Talk code to the object.
l In the Condition properties dialog box, click PlanetPress Talk before to enter PlanetPress Talk code that you
want the document to execute just before it evaluates the condition, or click PlanetPress Talk after to enter
PlanetPress Talk code that you want the document to execute just after it evaluates the condition.
6. Click OK.
