You class is already configured as spring bean so object will be available to activiti for execution.</SPAN><BR /><BR /><SPAN>Please let me know if this idea works.</SPAN><BR /><BR /><BR /><SPAN>Edit 1: Please ignore above ideas.</SPAN><BR /><BR /><SPAN>There are 2 ways to achieve this.</SPAN><BR /><SPAN>1. Use Delegate Expression</SPAN><BR /><SPAN>2. Use Expression.</SPAN></BODY></HTML> Sat, 26 Nov 2016 23:57:30 GMT https://connect.hyland.com/t5/alfresco-archive/javadelegate-injecting-filed/m-p/244705#M197835 anilmann 2016-11-26T23:57:30Z
