Lead which created by workflow is not able to qualify by the qualify button

Hi,

     I created a workflow which called from JavaScript in contact form and that creates a lead.If i click the Qualify button the lead is not qualified it just simply saved.

In the browser debugger i got this:

organization.crm.dynamics.com/.../web        POST    null            0 s    XMLHttpRequest

the POST call only in Pending status.

But if i Qualify a lead which manually created that gives status 200 ok . and qualified

please give the solution for this problem.

Thanks,

Mani
