Multi-Instance Sub Process has several errors when saving it in JBDS

1. In Business Central, create new repository and project, create business process named 'testMI', import attached org.jbpm.testMI.v1.0.bpmn2 to it and save.(1-process.png) 2. clone this project to JBDS by git(File->Import->Git->Projects from Git) and open the process => no problem 3, make cosmetic change (e.g. move end node to left a bit) and save it => you would see the error, see testMI-justAfterSave.bpmn2 2-process-justAfterSave.png 3-error-justAfterSave.png At this point, when looking at properties of MI sub process, these properties are set as expected. (4-MISubProcessProperties.png) 4. reset "Input Data Items" and "Output Data Items" after clearing these, specify appropriate data types for the errors something like the following and save it and confirm no error happens. Data input xxxxx had no DataType Data output xxxxx has no DataType Please note that Data Type need to be set for the following properties in JBDS which is not required in Business Central Input Instance Parameter (corresponding to MI data input) Output Instance Parameter (corresponding to MI data output) 5. perform git commit&push the changes to upstream(Business Central) 5. open modified process and confirm properties of MI Sub Process the followings are not set.(5-after-git-push.png) MI data input MI data output
