In certain MF activities (e.g. logging and dialogs), native widgets and also in pluggable widgets we have the option to use the so-called TextTemplate property/parameter.
Edited: Removed the request for java actions as Ivan pointed out that already exists.
I believe it was originally introduced in 8.5 with bunch of extra features down the line:
Hi Ivan, Thank you for pointing that out, I noticed it is new to Mx 8, would you know which release this came with?
Mendix already provides this feature for Java actions. See: https://docs.mendix.com/refguide/java-actions#string-template-type
Thank you Andreis, I did see the other ideas pass by when checking if anyone already thought of my request.
Extending the possibilities for parameters on MF/NF/widgets/java actions would be awesome. I noticed that the pluggable widgets are already an improvement in that area.
Nice one feature request!
It would fit into larger goals; to see the combination of all possible parameters of the Actions and Pluggable widget merge.
Including; Optional parameters for actions, Including default values.
