Populate Listbox Dynamically through Connected tool

The Listbox (interface macro) is currently populated statically when sourcing values through a Connected tool. Whatever, I configure in the macro is retained. When I use the macro in a workflow the LIstbox values are not updated when the fields in the connected tool are changed. This practically limits my capabilities to build a truely dynamic macro/app.

The Listbox should be able to show dynamically the fields coming in through the connected app.

how are you connecting the macro input to the listbox tool?

Hi GarthM,


I am using like this:



The input from Macro input you have showed works just fine(1st case) (which is a different from "Fields from Connected tool") but it is the data stream input, e.g. a select tool like here which does not update the list box. I still get the old values in the macro when used in a workflow.

gotcha. if you want to update the listbox dynamically you need a 'Q-to-Q' connection (i.e., Macro Input Q-Out.PNG to ListBox Q-In.PNG ). when you have a static list of values that will be used to populate a list you would create an "Anchor-to-Q" connection (i.e., Anchor-Out.PNGto Q-In.PNG).

yes, that's correct. But what if I want to update the list box based on some data stream but not macro input. The reason is because in case of macro input I would have to break it into 2 macros and connect them externally. I want to retain a single workflow and still want to update the list box dynamically. 

Please correct me if I am wrong.
