Name of the status must not contain CR or LF characters.

Hi,
while uploading a process (with extended tasks) via the rest api, sometimes (when process is a bit longer than usual) i get this error:

any idea on how to avoid it?

Seems like an exception occurs and the "message" of the exception contains CRLF-character. Do you see any exception prior to that in your log? Although very rare, this is an issue that needs to be addressed in the next version of activiti… I'll take care of that.

No error before this.
It is - somehow - random. i redraw the same process and the new one works.

The status-error has been resolved on master: https://jira.codehaus.org/browse/ACT-1740

If you really want to find out the original issue (masked by the exception about the status-name), you can use a custom ActivitiStatusService, based on the one committed on master…

[esseti]

since this error is showing up quite often lately, do you know how i can solve it?
or when there will be released in the jar? i would avoid to recompile the engine just for this error.

If you really want to find out the original issue (masked by the exception about the status-name), you can use a custom ActivitiStatusService, based on the one committed on master…

Create a subclass of the (5.13 in your engine JAR) ActivitiStatusService, e.g.. CustomActivitiStatusService and replace it with the implementation found on github (https://github.com/Activiti/Activiti/blob/8b3b750b9a2b88fbf888761ea6afe81c7012da9a/modules/activiti-...). Next, create a subclass of org.activiti.rest.application.ActivitiRestServicesApplication, overriding the constructor and AFTER the super() call, invoke  setStatusService(customStatusService). Last, but not least, replace the entry in web.xml for the rest-wabapp:


<!– Restlet adapter –> 
  <servlet> 
    <servlet-name>RestletServlet</servlet-name> 
    <servlet-class>org.restlet.ext.servlet.ServerServlet</servlet-class>
    <init-param>
      <!– Application class name –>
      <param-name>org.restlet.application</param-name>
      <param-value>com.mycompany.CustomActivitiRestServicesApplication</param-value>
    </init-param>
  </servlet>

Hope that helps…

[esseti]

thanks.
Still, i'm not too much into this things. i'll wait for the new relase .
