     3When this message is broadcast, the !DataController will attempt to delete a record from a given table. 
     4 
     5This message is configured by using the following <argument> tags: 
     6 
     7  1. Object (Required) - The name of the table from which to delete. 
     8  1. Criteria (Required) - A list of viewstate values to use as filters. Any value listed whose name matches a column in the target table will be used as a filter in the query's WHERE clause.

     12=== A Basic Generic Delete === 
     13 
     14To perform a basic delete on the Contact table, the following <message> tag could be added to an <event-handler>: 
     15 
     16{{{ 
     17<message name="modelglue.GenericDelete"> 
     18 
     19<argument name="object" value="Contact" /> 
     20 
     21<argument name="contactId" value="Contact" /> 
     22 
     23</message> 
     24}}} 
     25 
     26Assuming an event-handler name of "contact.delete", visiting the event handler with the following URL would result in deleting the contact with a !ContactId of 42.
