Toolbar and command doesn't appear on custom view. [message #490321]

In my plug-in, I intend to add a toolbar to my view and a couple of commands (push-buttons) to that toolbar.
I add a command and a handler to plugin.xml as :

        <command
            id="myorg.plugin.bottomView.filter.command"
            name="Filter">
     	</command>

         <handler
               commandId="myorg.plugin.bottomView.filter.command"
               class="com.myorg.eclipse.filterCommandHandler">
         </handler>

To add this command to a toolbar and that (toolbar) to my view I add this menucontribution to plugin.xml as :

<menuContribution locationURI="toolbar:myorg.plugin.bottomView">
	<toolbar id="myorg.plugin.bottomView.toolbar?after=additions">
            		<command
	                  commandId="myorg.plugin.bottomView.filter.command"
	                  icon="icons/filter.gif"
	                  tooltip="Filter results"
	                  style="push">
		</command>
            </toolbar>
</menuContribution>

My command and the expected toolbar doesn't appear on my view.
If I change my locationURI to following the command with it's icon shows up properly in main toolbar next to run command.

<menuContribution locationURI="toolbar:org.eclipse.ui.main.toolbar?after=additions">

I believe there is something wrong in the locationURI. myorg.plugin.bottomView is the id of my view.
I didn't find a document that describes correct syntax of the same.
So, what is wrong in here?
It'll be a great help if any expert tells me what it is.

Thanks.

Adding the command directly to the menuContribution (without the
toolbar) should work.

Hi Prakash,

Believe me I had tried that y'day but a typo - view name spelled wrong -caused all this exercise. Fresh day fresh outlook solved this in minutes.

Thanks anyways.

Sometimes it's necessary to customize the behavior of the existing i.e. the eclipse provided commands according to the business logic of the rcp application.

Example:

Let's say in general "Paste" command pastes the text from the clipboard. Now I want the paste command should paste text from clipboard with a prefix of "Hello".

Answer
The solution is to override the default handler with a custom one. But the problem with that is you can not declare a custom handler for existing command directly. It will raise a conflict.

So what we will do is we will activate the custom handler by activating a context.

Now, declare the custom handler like shown below:

<handler

class="<custom handler>"

commandId="<standard / existing command id>">

<activeWhen>

<with

variable="activeContexts">

<iterate

ifEmpty="false"

operator="or">

<equals

value="<custom context name>">

</equals>

</iterate>

</with>

</activeWhen>

</handler>

The above declaration will activate the custom handler when the declared context will be activated.

Now at the start up of the application you can activate the context by using following code.
Hope it did add some value.Any suggestions are welcomed.

Thanks

IContextService contextService = (IContextService) PlatformUI.getWorkbench().getService(IContextService.class);

contextService.activateContext( <custom context name> );

So now the above declared command will use the custom handler.
