After visiting the OPP/APEXPosed conference in Brussels I decided to write a post on how to create a relatively simple dynamic action in APEX. When you are working with password fields your only visual check to see if the entered text in both fields match may be the number of characters entered. Of course you can check for equality on submit but that may be a bit too late for the user.
For this post I will work with a textfield instead of a password field, but both will work the same.
A simple blank page will do.
When you open the context menu on the region you can choose to create a Page Item:
For the demonstration we will choose Text Field (that way what we enter will be visible)
Repeat these steps for the second page item:
Then select the kind of Dynamic Action you wish to create. We will be creating an Advanced Action
Then select the kind of page elements you want to be affected by this dynamic action.
