REST service with optional parameter -> misp2 doesn't generate an additional empty option tag for select-box

[aasaru]

I have a REST search service with optional header parameter of type enum:

        - in: header
          name: personType
          description: Filter by person type
          required: false
          schema:
            type: string
            enum: [INDIVIDUAL, LEGAL_ENTITY]

MISP2 generates the following SELECTbox out of this:

 <div class="field">
   <label>Filter by person type</label>
   <select name="personType" data-rf-param-location="header">
      <option value="INDIVIDUAL">INDIVIDUAL</option>
      <option value="LEGAL_ENTITY">LEGAL_ENTITY</option>
   </select>
 </div>

But Misp2 doesn't add empty option to the front (for the case if I don't want to specify anything).

The required behaviour would be that since the element is declared as required=false there should be an additional option tag in the front:

<div class="field">
    <label>Filter by person type</label>
    <select name="personType" data-rf-param-location="header">
      <option value="">--</option>
      <option value="INDIVIDUAL">INDIVIDUAL</option>
      <option value="LEGAL_ENTITY">LEGAL_ENTITY</option>
   </select>
 </div>

Thank you for reporting this problem to us.

I have created a backlog item in our JIRA to tackle this: https://nordic-institute.atlassian.net/browse/MISPDEV-85

Unfortunately, I can not offer a timeline for when we can introduce this improvement to MISP2 at this time.
