Fieldmapper from Setting types does not save entered alias and static value

[etharion]

When using the 'Send form to URL' workflow, filling out the fields in the 'Fields' mapper field does not save all information. 'Alias' and 'Static value' appears empty, when you open the workflow after hitting 'Save'. The number of mappings and 'Form value' is saved.

Reproduction

Specifics

Umbraco: 8.5.5 | 8.6.1
Forms: 8.3.1 | 8.4.1

Before:

After:

Steps to reproduce

1. Make a form with name, email etc
2. Configure workflow
3. Add new workflow
4. Select 'Send form to URL'
5. Fill out required fields + add 1 or more mappings in the 'Fields' mapper field
   a. When creating mappings, fill out alias and/or static value
6. Hit 'Submit'
7. Open the added workflow
8. Alias and static value data is missing

Expected result

I expect 'Alias' and 'Static value' to save the information entered in the field after hitting 'Submit'.

Actual result

It does not save 'Alias' and 'Static value' and entered information is lost after hitting 'Submit'.

Thanks for the report @etharion. This is a duplicate of #350 which we intend to work on in the next few weeks. For now the workaround is to add a new blank mapping after the last one and then save.

Apologies for the inconvenience!

I'll close this as a duplicate of #350
