Error Handling - Try/Catch Blocks

Hi,

I am looking to incorporate an error handling strategy using the try/catch blocks. Within my catch block i have a defined a workflow which calls another data flow. This data flow will write data to an error table, including the exception that was encountered.

Would you happen to know how is the exception being captured and how can I write it to the dataflow input?

I appreciate your help.

Thanks
