Although I define multi-instance parameters they are not contained in the resulting .bpmn process definition file. After re-opening the process, the respective fields in the subprocess' properties are empty. If you add the respective XML element manually, the fields in the subprocess' properties will contain the parameters, but they will be lost upon saving the file.
The link instructs on how to run the plugin as an eclipse project. I actually would like to build the plugin and update from my local filesystem. Is there any way of doing it? The updatesite package contains a site.xml which references a jar which is not built by the commands explained in the developer guide. What should I do to have my own local site and upgrade the installed plugin I have in my normal workspace? Thanks!
