Eclipse Code Assist with Composite Component and Custom Namespace fails - eclipse

Question

I made a composite component and declared a custom namespace in my taglib like this:
[...]
<namespace>http://www.#####.info/components</namespace>
<composite-library-name>composites</composite-library-name>
[...]
Now when I use that namespace:
xmlns:wb="http://www.#####.info/components"
Everything 'works Runtime' but Eclipse wont show any Code assist like when I use the 'default' namespace:
xmlns:wbcomposites="http://java.sun.com/jsf/composite/composites"
Is this a normal Eclipse behaviour or did I do something wrong ?
Edit:
For example when i write:
<wb:
And then press [STRG] + [SPACE] the code assist shows me that there are no components.
I think this behaviour would make the "user" think that he has done something wrong ...
I hope there is a way to fix this from my side..

Answer 1

The problem was that i mixed a normal component and a composite in the taglib:
<facelet-taglib xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facelettaglibrary_2_0.xsd"
version="2.0">
<namespace>http://abc/components</namespace>
<composite-library-name>composites</composite-library-name>
<tag>
<tag-name>something</tag-name>
<component>
[...]
Now i splitted them into to taglibs and two namespaces ...
This solved also bugs were the normal component was looked up as composite ...
