There are many places you can save the original value of
transactionptDisplayGroup.selectedObject.passThroughAmt. I often
override appendToResponse for this.
If you override takeValuesFromRequest, the return from
super.takeValuesFromRequest, will be the first place that all the
values entered by the user should be available to you. Before you
return from the overriding method, you can do all the arithmetic you
want to those values. However, don't do anything that will change the
structure of the template, since invokeAction hasn't yet been called.

I would like to know how to add a little math to the save method of
a Display Group.
I am using a display group to access records for modifying. The
returned records are displayed in Strings and one to be edited is
displayed in a Field. The user will enter a number into the field
and invoke the save component:
public WOComponent saveChanges()
{
try {
this.session().defaultEditingContext().saveChanges();
} catch (Exception e) { // could be more specific...
NSLog.err.appendln( "ViewEditInformation: saveChanges:
save error: " + e.getMessage() );
msg = "There was an error saving your changes: " +
e.getMessage();
return null;
}
msg = "Changes saved.";
return null;
}
The value they are modifying is called
"transactionptDisplayGroup.selectedObject.passThroughAmt". I would
like to know how to take the user's entered value and add 15 to it
prior to the save. Then I would like to take the value of
"transactionptDisplayGroup.selectedObject.passThroughAmt" before
their edit and subtract from it the value the user entered with the
added 15 and set the value of another field of the displayed group,
"transactionptDisplayGroup.selectedObject.salonPtRec". Finally, I
would like to save the results to the DB.
Any help would be nice. Thanks,
