[ https://issues.jboss.org/browse/DROOLS-3997?page=com.atlassian.jira.plugi... ] Daniel José dos Santos commented on DROOLS-3997: ------------------------------------------------ [~tirelli][~manstis] The issue is the namespace. I've imported an model with the name "Best Player" and look at this: xmlns:{color:red}Best Player{color}="https://kiegroup.org/dmn/_47F64FEB-F517-4B98-B270-E04... I changed it manually to "BestPlayer" (without space) and it worked in DMN Showcase (before that change the model was not being loaded), but I'm not sure about the side effects of having the declaration here without space and the name with spaces in the other places: <dmn:import id="_A55C41D2-E76A-467A-B97A-3C8F3A063F0D" {color:red}name="Best Player" {color}namespace="https://kiegroup.org/dmn/_47F64FEB-F517-4B98-B270-E049FC5E21CE" locationURI="default://master@system/stunner/diagrams/nrBzl8oV.dmn" importType="http://www.omg.org/spec/DMN/20180521/MODEL/"><... <dmndi:DMNDI> <dmndi:DMNDiagram> <di:extension> <kie:ComponentsWidthsExtension></kie:ComponentsWidthsExtension> </di:extension> <dmndi:DMNShape id="{color:red}dmnshape-Best Player{color}:_B5CE43A7-B81C-4A41-AD9C-6019453912D6" dmnElementRef="{color:red}Best Player{color}:_B5CE43A7-B81C-4A41-AD9C-6019453912D6" isCollapsed="false"> -- This message was sent by Atlassian Jira (v7.12.1#712002)
