I've built a plugin with no issues and registered it using plug-in registration tool with no problem but its seems like it has no effect the plug-in force calculation for a roll-up field named rejected on vacancies entity where rejected is the count of application that if status =inactive
Anyway i used a custom workflow from workflow tool CodePlex named force \recalculate roll up fields which work fine and automatically perform roll ups once status goes into inactive but the issues is when i deleted the record the workflow didn't trigger in real time which force me to make a plugin i will provide a screen shots about my plugin to explain everything
the plug-in it-self which force calculation whenever a change occur
here is how i registered the plug
in on update if attributes rejected or active changed which by them i mean the fields changed make force the roll to occur
sorry for the long question
Best Regards
