All these properties works at component level. Like after component edit is completed, or delete etc. My requirement is lets say i have 2 widgets in component , after editing the value in first widget i am setting values for 2nd widget that is dropdown(multifield dropdown). These values are not picked at runtime, page need to be refreshed for this. So i want the things to work without refreshing the page. Isn't AEM has anything workaround for this problem?

This is not working. Once i refresh the page then it is loading the new values in the dropdown. I am looking something which can be achieved without closing the dialog and page refresh.

I don't remember full but there is js code which makes ajax call to pulldynamic values and populated them using jquery and coral ui.

I had set default value(i have shared all my code in post), still i have to open the configuration and save once to bring servlet in satisfied state.

I finally solved this, though it was very weird, first we have to save the configuration then servlet will become in 'satisfied' state.Once servlet is in satisfied state we can call the same in url.Thanks everyone for helping me on this.Regards,Pradeep

Hi Donald,No luck,  same error,  servlet is in unsatisfied state.

Hi Donald,In AEM 6.4 There is a entirely different approach to read config values. That i am trying to understand how to implement it.

I followed the same link, not working in  sling servlet.
