    Hi Vasantha -

    The IAPI scripting allows you to chain exceptions and throw the full list after all validations are complete. This sample code shows how that is done:

    // Create Application Exception to hold exceptions
    ApplicationException ae = new ApplicationException(session);
    // Perform validation here...if there is an error,
    // chain a new exception to the list
    ae.chainAtEnd(doc.createApplicationException("field id", "resource id"));
    // Perform additional validations here...
    // If we get to the end and have some exceptions, throw them now
    if (ae.getChain() != null)
        throw ae;

    The concept is to create an initial exception, add (chain) all exceptions to that initial exception, and throw the initial exception at the end once all validations are complete.

    Hope this helps.
