Extension point no extensible is same plugin ? [message #137307]

I've create an extension point in my plugin (under development).
It's seems that I can't extends this point in same plugin, plugin.xml
parser
barks "Unknown Extension Point:..."

It is a limitation of the plugin engin ?

No. Maybe you might have misspelt your extension point name.
For e.g.
<extension-point id="statuschangelisteners" name="XYZ Change Status
Listener"

schema="schema/statuslistener.exsd"/>

<extension

point="xyz.statuschangelisteners">

<statuschangelistener

class="xyz.views.MyStatusChangeListener">

</statuschangelistener>

</extension>

xyz is the name of the plugin

Thanks a lot Balaji !

I'd just to know the extension must start attribute point with the plugin
id 'xyz' before name.

In addition extension-point id seems to no support '.' character in their
names.

Thanks.

It would be helpful to append the definition of the extension point and
the usage of the extension point and the header element from your
plugin.xml so that we can see if there is semantic error here.

I am curious, why would you want the plugin that provides the extension
point to extend itself via an extension in the plugin.xml? Couldn't you just
code it to do this without declaring it as an extension?

That's one of Eclipse's fundamental design principles:
Whenever we open up an implementation (by creating a new extension point) so
that others can provide their own extensions, we play by the same rules and
use that extension point ourselves. There should be no first class
citizens...

But adherence isn't 100%, is it? Does Eclipse (the team) have a count of the
instances where Eclipse (the software) violates the rule? No measure, no
management.

Sure, for this rule: 0
