I am in the process of moving some of my development work from colfdfusion 9 to coldfusion 10. Run into a problem with one section of an application. Basically a form gets completed and then submitted - this works perfectly with vrs 9 but on version 10 I get the following error after hitting the submit button. The form passes a hidden variable which is a value list to the action page. It would seem that this value list is too big for coldfusion 10 to handle, but ok with Vrs 9 ?

=====================================================================
ERROR HTTP 400  POST PARAMETERS EXCEEDS THE MAXIMUM LIMIT

The request sent by the client had syntax problems - POST parameters exceeded the maximum limit

Apache Tomcat/7.0.23
===================================================================

Are there some settings i need to set on version 10 ? or some functionality which is no longer supported on version 10 ?

Attached is the client pageFORM-update-ChequesHELD.txt.

Yes.  They added a new feature that limits the number of form fields you can post to protect against a certain type of DOS attack. The default limit is 100 form fields. More than that causes an error.   You can read more about it here:

In CF 10, this setting can be changed through the CF Administrator. Under Server Settings, increase the "Maximum number of POST request parameters" value from 100 to whatever is appropriate for your app.
