Hi Kavitha,

Thanks for using the plugin.

This error look familiar to me, I suggest you upgrade to Grails 2.x and use latest version of the plugin.

Hope this help.

Best regards,
Chee Kin

Hi Kavitha,

In the case of you have your own User and Role domain class implemented, you need to make sure that the domain classes implement org.activiti.engine.identity.User for User domain class and org.activiti.engine.identity.Group for Role domain class.

Please see sample code at https://github.com/limcheekin/activiti-spring-security/tree/master/misc/grails-app/domain/org/grails/activiti/springsecurity

Hope this help.

Best regards,
Chee Kin

I'm having precisely the same problem. I'm using grails 2.2.1 and the activiti plugin 5.12.1. The problem is that the schema activiti attempts to generate specifies an attribute type which is not supported in mysql. Unfortunately I currently have no idea how to work around this.

For any assistance, many thanks in advance.

Hi, 

I just started to investigate capacities of this plugin but maybe it can be possible to change in some place "longvarbinary" with "blob"
