PeopleTools Bug

If you are coding an Application Package, and you get this error message:

PeopleTools Affirm Triggered
PSAFFIRM(!pItemFound) failed at e:\pt846-908-r1-retail\peopletools\src\inc\stringhash.h, line 157. See trace file. Press Cancel for debugger.

Here is the solution:

Basically, you have a property with the same name as one of your instance variables. For example:

class ExampleClass
method ExampleClass();
property String ExampleDescription get set;
private
instance String &ExampleDescription;
end-class;

To fix the problem you can change it to:

class ExampleClass
method ExampleClass();
property String ExampleDescription get set;
private
instance String &strExampleDescription;
end-class;

PeopleTools Reference: Common Meta-SQL

If you were to learn just a select few Meta-SQL, these are the ones that I would recommend:
%SelectAll
%SelectAllByKey & %SelectAllByKeyEffdt
%Table
%DateIn & %DateOut
%Insert
%Update
%Delete

There are many others. Please refer to the PeopleTools PeopleBook for more information.
