KB-2029 Unable to save value in Interface Designer when rule input is named "action"

Symptoms

When setting a save into value for a rule input named ri!action, the value is not saved in the Interface Designer rule input.

The SAIL code resembles this:

saveInto: ri!action

Users will also see this behavior when using the Interface Designer to add and map a button to a rule input labeled as ri!action.

Cause

The "action" keyword disables the Interface Designer from saving the value properly. The actual function of the code works fine in process, just not in the Interface Designer. This issue has been reported to the Appian Product Team. The reference number for this issue is AN-109013.

Workaround

The most straight-forward workaround is to rename the rule input to something other than "action."

Another workaround to this issue is to use a!save like so:

saveInto: a!save(
ri!action,
save!value
)

This explicitly defines the target and the value to be saved.

Affected Versions

This article applies to Appian 17.4 and later.
