I have a component library. It has a manifest file that looks like this:

```
<?xml version="1.0"?>
<componentPackage>
    <component id="AutoComplete" class="be.edge.components.AutoComplete" />
    <!-- more components left out for brevity -->
</componentPackage>

```

I compile the library through FlashBuilder with these compiler settings:

![FlashBuilder library compiler namespace inputs](https://i.stack.imgur.com/hmKTk.jpg)

When I use the compiled library in other FlashBuilder projects everything works as expected. I get code completion and when I select a suggestion from the code completion a namespace attribute is automatically added to the component, like this:

```
<s:Skin xmlns:fx="http://ns.adobe.com/mxml/2009" 
        xmlns:s="library://ns.adobe.com/flex/spark" 
        xmlns:ns="library://ns.edge.be" >

    <ns:AutoComplete />

</s:Skin>

```

**But:** FlashBuilder automatically creates the prefix 'ns'. I would like to customize this to 'e' for instance. How can I make FlashBuilder use this custom prefix by default?

I have two reasons for this:

1. 'ns' doesn't say anything: it just says *A namespace* has been used, not what namespace.
2. when I use other libraries that also start with a url like 'library://ns.' FlashBuilder will probably start numbering the prefixes to resolve the conflict (ns, ns1, ns2, etc.), which would be even more confusing.

**EDIT:**

I also pass a config.xml to the compiler that has the following declarations relating to namespaces:

```
<compiler>
    <namespaces>
        <namespace>
            <uri>library://ns.edge.be</uri>
            <manifest>manifest.xml</manifest>
        </namespace>
    </namespaces>
</compiler>

<include-namespaces>
    <uri>library://ns.edge.be</uri>
</include-namespaces>

```
