The injection configuration for parameter <parameter> is specified through both attributes and child value elements

I'm getting this error when trying to resolve a type:

public sealed class CustomApplicationUpdateProvider : ApplicationUpdateProvider
{
    IUpdateProviderController controller;

    public CustomApplicationUpdateProvider(IUpdateProviderController controller)
    {
        this.controller = controller;
    }
    //more code here ....
}

using this configuration:

  <Unity>
    <typeAliases>
      <typeAlias alias="IUpdateProviderController" type="example.IUpdateProviderController, example" />
      <typeAlias alias="UpdateProviderController" type="example.UpdateProviderController, example" />
    </typeAliases>
    <container name="RealContext">
      <register type="IUpdateProviderController" mapTo="UpdateProviderController"/>
      <register type="CustomApplicationUpdateProvider">
        <constructor>
          <param name="controller" parameterType="IUpdateProviderController">
            <dependency/>
          </param>
        </constructor>
      </register >
    </container>
  </Unity>

I'm using Uni开发者_JAVA百科ty 2.0

any ideas?

Remove parameterType="IUpdateProviderController" attribute.
