As per the jira issues https://activiti.atlassian.net/browse/ACT-1963 and https://activiti.atlassian.net/browse/ACT-1847 the support for data objects is already in modeler for the 5.18 release versions. I am using 5.18 but fail to see the data object support in the modeler pallet for process / sub processes. Can somebody please confirm whether they are incorporated or we might have to write this as a plug as we do not want to change the source code internally.
