how to pass and return integer type of attribute in rulesheet for plugin
The Corticon Extension Guide (documentation.progress.com/.../corticon_extensions.pdf) details how to do this. You can also look at the bundled Extended Operator sample for example code. I don't know if there is a sample specifically for integers but it code would be similar; you would need to implement ICcIntegerExtension and the method(s) would return BigInteger.
