[rules-users] Changing asset metadata properties in Guvnor

Hi guys! I am quite new to Guvnor so i would like to ask you for some assistance. I need to change Guvnor asset metadata property by using REST Api. I am sending XML <asset> <author>test</author> <binaryContentAttachmentFileName/> <binaryLink> http://localhost:8080/guvnor-5.5.0.Final-tomcat-6.0/rest/packages/mortgag... </binaryLink> <description/> <metadata> <checkInComment>disabled</checkInComment> <created>2013-03-20T18:53:55.253+02:00</created> <disabled>false</disabled> <format>brl</format> <note></note> <state>Draft</state> <uuid>5c8b1767-d9ee-42fa-bb4d-ab0e2b37aff5</uuid> <versionNumber>43</versionNumber> </metadata> <published>2013-03-22T11:41:52.018+02:00</published> <refLink> http://localhost:8080/guvnor-5.5.0.Final-tomcat-6.0/rest/packages/mortgag... </refLink> <sourceLink> http://localhost:8080/guvnor-5.5.0.Final-tomcat-6.0/rest/packages/mortgag... </sourceLink> <title>bobik</title> </asset> to my url : http://localhost:8080/guvnor-5.5.0.Final-tomcat-6.0/rest/packages/mortgag... via HTTP PUT and nothing exept version number of the asset is changed. Do you have any ideas why is that? -- Best regards, Viktor
