Change name of primary button from "Next" to "Submit"

You can change it but that will change it in all forms as explained here: forum.appian.com/.../4341

The updated path for the internationalization bundle is: <APPIAN_HOME>\\ear\\suite.ear\\resources\          ext\\jsp\\forms\          emplates\\controls

We have had the same issue, and our solution to this is that we have two constants for the button's label and value.

Constant for button label: "Submit "
Constant for button value: "Submit"

By putting a space in the label will prevent Appian from renaming it to Next.

For more details, go to forum.appian.com/.../Button_Field_Input
In the documentation, this might be what you want to read:

If you do not modify the Label value and the form is for an attended node that is activity-chained to the next node in the process model, the label will display to users as Continue on Tempo forms and Next on legacy forms.

Hope it helps.
