RE: Dynamic link Action

I do not see any obvious reason for it to not work.

Could it be that you created the local first without assigning a value (zero)? In Appian, trying to add 1 to NULL evaluates to NULL. To make sure this is not the case, refresh the interface by clicking the "TEST" button.

Simple example:

a!localVariables(
  local!finalCount: 0,
  a!linkField(
    links: a!dynamicLink(
      label: "+1",
      value: tointeger(local!finalCount) +1,
      saveInto: local!finalCount
    ),
    instructions: local!finalCount
  )
)

RE: Dynamic link Action

Stefan Helzle — Wed, 19 Jul 2023 09:02:12 GMT

In general that would require a simple local variable that you initialise with zero. In the dynamic link, you assign the value of the local variable + 1 and save it into local variable.
