Re: The following required parameter is missing: [IN]

You should use two different request-map entries pointing at the same view:

  <request-map uri="CreatePersonForm">
      <security https="true" auth="true"/>
      <response name="success" type="view" value="createPerson"/>
  </request-map>


used when you visit the page; and:

  <request-map uri="createPerson">
      <security https="true" auth="true"/>
      <event type="service" invoke="createPerson"/>
      <response name="success" type="view" value="createPerson"/>
  </request-map>



used when you post data

I've added the IN parameters but still I get the error. I think I know
what happens but don't know how to fix it.

I get the error on the moment I enter the page. When I fill the
firstname en lastname field and press submit the error disappears and
the person is added to the database. So, I think that the service is
also called on the moment I enter the page.

Could my analyses be right? And how can I fix it?

Hello Roel,

In Your Service Definition you have not defined the in Parameters.

Also In controller entry you dont need to make enrty for Handlers and

Pre-processors as you have included common-controller and this entries are already their. Please see my amendment inline. Also write code for creating Party first and then go for creating Person.Also see example component for

reference as suggested by Pranay.

I made a form to add a basic person ( firstname, lastname). But
(Although the main functionality of the form works, it's adding a
person) the following errors occur:

The Following Errors Occurred:
The following required parameter is missing: [IN]
[createPerson.firstName]
The following required parameter is missing: [IN]
[createPerson.lastName]

Why do they occur?

Form:
<form name="createPerson" type="single" target="createPerson">
    <field name="firstName"><text/></field>
    <field name="lastName"><text/></field>
    <field name="submit"><submit/></field>
</form>

Widget:
<screen name="createPerson">
