In dialog there are two drop downs, values are coming from backend usingservlet call. Once the author selects the field in dropdown i need to make the call to another servlet based on first drop down selected value and show the options. How to achieve this, i am using classic ui. Please help.
As you are working in Classic UI - to perform this use case, you need to write a custom xtype. In the code of the custom xtype, you can invoke the servlet.
Details here on how to write a custom xtype that shows how to populate a 2nd field based on the 1st selection (in your use case, populate the 2nd with the values returned from the servlet):
Hope this helps....
Thanks for the prompt reply!
My query is still not resolved, i can elaborate my question more: Based on first drop down selected value i need to pass it as a parameter to the second drop down's servlet and again once the user select the second drop down value there is third drop down which makes a call to third servlet with second drop down selected value as a parameter.
