In the LLBLGenPro Designer v3.1 I'm allowed to have two model views with the same name (e.g. "Test") and when I try to reopen the "llblgenproj" file, it generates an ArgumentException "An item with the same key has already been added" as attached below. It took me some time to discover the correlation between the two.

Shouldn't non-unique identification of model views (or other objects for that matter) be disabled?

Exception information.

Inner exception: <null>

I reproduce it. It's no admitted to have the same name on Model Views. It should be a check when you create one.

We will look into it. In the meantime, as you can't open your project, open it in a notepad, then browse your model views and rename one:

  <ModelViews>
    <ModelView Name="Xyz">
      <EntityDefinitions>
        <Entity Name=":Customer" />
        <Entity Name=":Order" />
      </EntityDefinitions>
      <Documentation><![CDATA[]]></Documentation>
    </ModelView>
    <ModelView Name="Xyz">
      <EntityDefinitions>
        <Entity Name=":Product" />
        <Entity Name=":Region" />
        <Entity Name=":Shipper" />
      </EntityDefinitions>
      <Documentation><![CDATA[]]></Documentation>
    </ModelView>

then save and reopen your project. We will look into this.

Ah, I see where the issue is. Normally, one creates a modelview by selecting the entities, then specifying the modelview, and if you specify an existing one, it will add the entities to that modelview. Creating a new one uses a different codepath for creating the modelview. We'll add a check there, it's an oversight.

Fixed in next build.

Excellent, thanks!
