Variable Web Block output

Variable Web Block output

  
I am trying to build a Web Block that will select a value from a Record List (using a List Box), and populate a screen field. I want to use this as a widget for several fields on the screen, each with a different Record List and screen field. I can specify the Record list as an input parameter, but how can I specify the screen field that stores the selection?
 
 
Hi.
 
You should avoid , whenever possible, RecordLists as input parameters.
 
Regarding the output (with the result of the selection), you can use the System action NotifyWidget, that way, the web block consumer will be "notified" about the user selection choice, you only need to assign the identifier to the "Message" parameter.
 
There are a few posts about how to achieve that:
