Values become NULL after changing series item name

Question

Hi, I'm new to Knowage, I create a line chart, which shows good, but after I rename the series item as shown, the values become NULL. How can I solve it? Thank you.

Hi luna123,

as a general recommendation I'd suggest you not to use spaces in your names: instead of using "New Name" try "New_Name" instead.
Then try to check the logs and the browser console to find any errors that may have prevented correct execution.

Bye,
Marco

Hi Marco,

I remove the spaces in names but the problem is still here. I checked with the browser console, it reports:

TypeError: Cannot read property 'updateContent' of angular.js:15570 undefined

TypeError: Cannot read :8080/knowagecockpitengine/js/lib/angular/angular_1.4/angular.js:12793 property 'toLowerCase' of undefined

Uncaught TypeError: Cannot read chartJsInitializerService.js:284 property 'datasetLabel' of undefined
    at HTMLCanvasElement.chartPanelCanvas.onclick (chartJsInitializerService.js:284)

In knowage.log, it reports:

ERROR it.eng.spagobi.rest.interceptors.RestExceptionMapper.toResponse:59 - Catched service error:
javax.ws.rs.NotSupportedException: RESTEASY003065: Cannot consume content type

I changed the host_url variable in server.xml to the actual URL and restart service with sudo, but it is not working.
