In WebSphere Commerce Version 6.0, when PIAddCmd is called with a blank field for PPCExtData, an encrypted value is used in its place. This however was changed in WebSphere Commerce Version 7.0 to throw an exception in the case any required parameter returns null.

If the parameter is not being used, resolve the issue by removing the applicable property (in this case 'cc_brand') from your payment plug-in configuration file (in this case SimpleOfflinePlugin.xml) and the plug-in deployment descriptor file (PluginDeployment.xml).

Ensure that you restart the server after making the change.
