Unknown Component Type

Postby impulse101587 » Thu Oct 08, 2015 3:59 pm

Hello All,

I am receiving an odd error while running a simple graph execution using a Universal Data Writer. Anyone have any thoughts on this?

Clover Server 4.0.0.44/44 on linux

Throws this error:

Error loading job file: sandbox://Accounting/graph/new-graph.grf
Unknown component type: DATA_WRITER
Unexpected null value

With this stack:

Hi impulse

Please send me the graph with the mentioned UniversalDataWriter, so I can try to reproduce the issue. Also, I have a couple of additional questions:

    1. Which version of the Designer are you using with said server?
    2. Have you recently upgraded/downgraded your Server or Designer (if so, from which version)?
    3. Please re-run the graph in the debug mode and send me the 'all.log' (located in <tomcat_home>/temp/cloverlogs).
    4. Did you do any changes to the source code (XML) of the component or the graph?

Thank you.

Best regards
