SpagoBI: MODEL INSTANCE IS NULL, CHECK model_node_instance IN DOCUMENT TEMPLATE.!

Question

What you read in the title is literally the error I see in the log when I try to execute a KPI document.

I followed the instructions available here: http://wiki.spagobi.org/xwiki/bin/view/spagobi_server/KPI+Document+Definition

Here's the full trace of the error:

Answer 1

check the value of the model_node_attribute in your the Kpi Document template.

The value of this attribute must be the same of the Label field of your Model Instance.

For example in the SpagoBI Model Instance Definition sample enter image description here the value is: d09075030-5476-4bab-8...

so your xml tag must be like this:

... KPI model_node_instance='d09075030-5476-4bab-8...' name='Title of the document'> ...

Bye!
