[MarkLogic Dev General] trigger not getting invoked in a clustered environment

[Raghu]

Hi Danny,

   Thanks once again. I'm not using any content processing framework. Its
just an xquery. I don't have the luxury of adding  nodes. Any ways it isn't
throwing up any errors in the logs that is what is keeping me guessing.I
will let you know if I find something interesting!

Thanks
Raghu
