Hi, I have some questions about JBPM/JPDL Api (maybe a minimal part question of a very long future list of questions... sorry) I'm rewriting a task "to do list"... like the jbpm-console. Why ? 1) Because jbpm-console doesn't manager authorizations (http://www.jboss.com/index.html?module=bb&op=viewtopic&t=141654) 2) Because I want a standard user interface between my ERP and WorkFlow system .... about point 2): 2.a) how can I get a task/process instance image rappresentation ? I know I can get the jpg image of the process definition using ProcessDefinition vPD = vJbpmContext.getGraphSession().loadProcessDefinition(aProcessDefinition); vBytes = vPD.getFileDefinition().getBytes("processimage.jpg"); and there is a very good example for process instance at http://www.jboss.com/index.html?module=bb&op=viewtopic&t=102817 (thank you very much Mr. dleerob). But.. there is a more simple way ? like the getBytes("processoimage.jsp" ... directly from standard jpdl api? Will be implements in a future release? 2.b) I can define variables. It is possible to define 3 properties : "required", "read", "write" What's about nature of the field ? e.g. a list of value or if it is a number (and maybe the precision) or is a string, a date and so on? If it is possible to define this additional properties... how can I get it from jpdl api? I'm try also to get a look to java source code of the jbmp-console, but it is not so simple to found all response thank you to all.
