There is a problem that has occured while building on top of Eclipse plugins.
I have isolated the problem and was able to re-create it using PDE-Example.
Scenario:
1. Create a Hello World Sample (Plug-in Project with a View) inside the PDE 
environment perspective.
2. A plugin project should be created with plugin.xml and the extension point 
for the view looks something like this:
   <extension
         point="org.eclipse.ui.views">
      <category
            name="Sample Category"
            id="HelloWorld">
      </category>
      <view
            name="Sample View"
            icon="icons/sample.gif"
            category="HelloWorld"
            class="HelloWorld.views.SampleView"
            id="HelloWorld.views.SampleView">
      </view>
   </extension>

3. Create a plugin.properties file in the plugin project with the following 
entry:
Helloworld.sample = Sample View 100
4. Now update the extension point for the view in plugin.xml file with this:
   <extension
         point="org.eclipse.ui.views">
      <category
            name="Sample Category"
            id="HelloWorld">
      </category>
      <view
            name="%Helloworld.sample"
            icon="icons/sample.gif"
            category="HelloWorld"
            class="HelloWorld.views.SampleView"
            id="HelloWorld.views.SampleView">
      </view>
   </extension>

Note: The name for the view is referencing the key in the properties file.
5. Now Bring up the Runtime workbench and you should see the Sample View 100 by
going to Window --> Show View --> Other... --> Sample Category --> Sample View 
100 click on it and bring up this Sample View 100.
6. Now bring down the runtime workkbench
7. Change the value in the plugin.properties file as follows and save:
Helloworld.sample = Sample View 200
8. Bring up the workbench and the Sample View 100 is seen but not the Sample 
View 200 as the property has been changed in the plugin.properties
9. Tried a variation now by changing the plugin.xml extension point as follows 
and it worked once when I re-bring up the workbench:
   <extension
         point="org.eclipse.ui.views">
      <category
            name="Sample Category"
            id="HelloWorld">
      </category>
      <view
            name="Sample View 300"
            icon="icons/sample.gif"
            category="HelloWorld"
            class="HelloWorld.views.SampleView"
            id="HelloWorld.views.SampleView">
      </view>
   </extension>
10. But now if I repeat step 4, I would see it still works and I see "Sample 
View 200" as specified in the properties file.
11. Now if I repeat step 7 and change the value in the properties file to
Helloworld.sample = Sample View 400
and bring up the workbench it again fails to pick up the Sample View 400 but 
stays at Sample View 200.

I know the problem seems to be a little tricky to reproduce, I tried to explain 
it as clearly as I could, if there are any other questions please feel free to 
contact me.
We need this name of the view in plugin.properties as we need the name of the 
view to be transalted.
Hoping to hear back from some one soon. Thanks.
