Description of problem: BPMN2 specifies (among other things) how the nodes should be drawn. The editor in eclipse does not respect these requirements. This may cause confusion when customers come from Guvnor web-based editor to JBDS and vice versa.
I created a list of problems following the BPMN2 specification: * The marker for a Task that is a multi-instance MUST be a set of three vertical lines. (there is nothing in eclipse) * A Business Rule Task is a rounded corner rectangle that MUST be drawn with a single thin line and includes a marker that distinguishes the shape from other Task types. (there is no mark in eclipse) Also the markers are different (but I don't know whether that is a part of specification) - user task, script task, timer node, signal node. Nodes that are not supported by eclipse editor are (naturally) not drawn correctly. This category contains (but is not limited to): different types of start/end/intermediate/boundary events, ad-hoc processes, swimlanes.
We're not planning to improve the "old" eclipse process editor (Drools Flow / RuleFlow) anymore and this will be addressed in the new Eclipse BPMN2 modeler. So closing this one as won't fix.
