Component Interface Properties Field insert issue

Hello,

We are currently utilizing a custom voucher component interface. We feed the data to the CI from a custom table using a custom app engine program. During a test run, I understood that vouchers are getting created even when some of the Properties fields are not getting populated as expected. For one such field, the log file message was "value is too long for the field X".

I would like to capture this messages (and potentially other ones similar to this) and insert them into a table for reporting/awareness purposes. Since these fields are not preventing the CI from being created or saved, I am not sure how to capture them via the app engine. Any suggestion would be appreciated.
