i quite new in developing for CRM WebUI. In my first project i face a problem with subscribe an event from BP_HEAD. I need do receive an event if the Save Button is press to save change. I build a "Z"-component that i add via ComponentUsage to BP_HEAD. Bind PARTNER Context in the BP_HEAD-Component Controller via IV_USAGE->BIND_CONTEXT_NODE was no problem. But how can i subscibe an event from BP_HEAD to trigger my Z-Component to save BPARTNER independent Data? I'm unable to get a referenz of my z-component in the Method "WD_USAGE_INITIALIZE" of the BP_HEAD-Component Controller.
Hope somebody can give me a hint.
