How to hide userdefiened menu item under search menu in Eclipse PDE

Can someone tell what is wrong with the below code. It is not working. When perspective changes it should hide respective menu item.
<extension point="org.eclipse.ui.menus">
<menuContribution locationURI="menu:org.eclipse.search.menu?after=xxxGroup">
<command commandId="com.xxx.udt.ui.xxxOpenFileSearchPage"
label="XXFS"
mnemonic="%XXXOpenFileSearchPage.mnemonic"
icon="icons/full/search/XXXSearchDialog.png"
helpContextId="file_search_action_context">
<visibleWhen
checkEnabled="false">
<with
variable="com.XXX.udt.ui.serviceprovider.ShowActions">
<equals
value="showAction">
</equals>
</with>
</visibleWhen>
</command>
</menuContribution>
</extension>
<extension
point="org.eclipse.ui.handlers">
<handler
commandId="com.XXX.udt.ui.MCPOpenFileSearchPage"
class="com.XXX.udt.ui.MCPOpenFileSearchPage">
</handler>
</extension>
The visibleWhen expression to check the current perspective is something like:
<visibleWhen>
<with
variable="activeWorkbenchWindow.currentPerspective">
<equals
value="org.eclipse.pde.ui.PDEPerspective">
</equals>
</with>
</visibleWhen>
This particular expression is testing for the Plug-in Development perspective.
Please refer to https://wiki.eclipse.org/Command_Core_Expressions for clear usage of visible-when and enable-when conditions..

How to hide tabs in search widget based on activePerspective in Eclipse PDE?

I'm trying to hide tab created by us in search widget when perspective changed to some other perspective. I trying put some condition in plugin.xml page but didn't succeed in that. Below is the extension I have to hide.
<extension
point="org.eclipse.search.searchPages">
<page
canSearchEnclosingProjects="true"
class="com.xxx.udt.ui.MCPFileSearchPage"
icon="icons/full/search/xxx.png"
id="com.xxx.udt.ui.page2"
label="MCP Search"
showScopeSection="false"
tabPosition="1">
<!-- <enabledWhen>
<with variable="com.xxx.udt.ui.serviceprovider.ShowActions">
<equals
value="showAction">
</equals>
</with>
</enabledWhen> -->
</page>
<enabledWhen>
<with variable="com.xxx.udt.ui.serviceprovider.ShowActions">
<equals value="showAction"/>
</with>
</enabledWhen>
The org.eclipse.search.searchPages extension point does not support hiding pages based on the perspective (or anything else).
Steps to hide menu item in search menu :
1>Create a menu contribution.
2>create a command for the same.
<extension point="org.eclipse.ui.menus">
<menuContribution locationURI="menu:org.eclipse.ui.main.menu?after=navigate" >
<menu label="Search"
id="org.eclipse.search.menu"
>
<command commandId="com.unisys.udt.ui.OpenFileSearchPage"
label="%action.FileSearch"
mnemonic="FS"
icon="icons/full/search/SearchDialog.png"
id="com.unisys.udt.ui.OpenFileSearchPage">
</command>
<visibleWhen
checkEnabled="false">
<with
variable="com.udt.ui.serviceprovider.ShowActions">
<equals
value="showAction">
</equals>
</with>
</visibleWhen>
</menu>
</menuContribution>
</extension>
3>create a handler.
<extension
point="org.eclipse.ui.handlers">
<handler
class="com.udt.ui.handlers.OpenFileSearchHandler"
commandId="com..udt.ui.OpenFileSearchPage">
</handler>
4>create one activitypattern binding for the same.
<activityPatternBinding
activityId="xxx.contributions"
isEqualityPattern="true"
pattern="com.udt.ui/com.udt.ui.OpenFileSearchPage">

How to add an item to the refactoring popup menu in Eclipse plug-in

I have written a simple Eclipse plug-in and wanted to extend the Refactor (alt+shit+T) menu with a new item that would invoke my code.
Unfortunately, after having spent hours researching the possible solutions, I have failed.
I tried some solutions suggested online, but none worked, maybe because I'm using the latest Eclipse Luna and from what I understand the refactoring menu is (was?) defined as something called action sets, and it's apparently deprecated now.
I was able to extend the top-level popup menu using the new commands API, but that's not what I want.
I would just love to see a working example of plugin.xml that adds a custom item to the Refactor popup menu.
Just for the reference, this doesn't work:
<extension point="org.eclipse.ui.menus">
<menuContribution locationURI="menu:org.eclipse.jdt.ui.refactoring.menu?after=typeGroup">
<command
commandId="mycommandid"
label="mycommandlabel">
</command>
</menuContribution>
</extension>
<extension point="org.eclipse.ui.commands">
<command
id="mycommandid"
name="mycommandname">
</command>
</extension>
<extension point="org.eclipse.ui.handlers">
<handler
class="MyHandlerClass"
commandId="mycommandid">
</handler>
</extension>
Try this
<extension
point="org.eclipse.ui.popupMenus">
<objectContribution
id="org.forsp.StringHelper.contribution1"
nameFilter="*.*"
objectClass="org.eclipse.ui.IEditorInput">
<menu
id="org.forsp.StringHelper.menu1"
label="Menu"
path="additions">
<separator
name="group1">
</separator>
</menu>
<action
class="org.forsp.stringhelper.popup.actions.NewAction"
enablesFor="1"
id="org.forsp.StringHelper.newAction"
label="New Action"
menubarPath="org.forsp.StringHelper.menu1/group1">
</action>
</objectContribution>
</extension>

Contribute a menu item to the "Configure" menu item/group in Project Explorer

I'm trying to contribute a menu item to the Configure menu item/group in Project Explorer.
The following snippet adds my menu item to the same level. Adding <menu label="Configure" /> between <menuContribution ...> and <command ...> creates a duplicate Configure menu item.
What am I doing wrong?
<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.4"?>
<plugin>
<extension point="org.eclipse.ui.menus">
<menuContribution locationURI="popup:org.eclipse.jdt.ui.PackageExplorer">
<command commandId="com.example.convert" label="Convert to XXX Project..." />
</menuContribution>
</extension>
<extension point="org.eclipse.ui.commands">
<command id="com.example.convert" defaultHandler="com.example.ConvertAction" name="Convert to XXX Project" />
</extension>
</plugin>
Using org.eclipse.ui.menus is the more future-safe way so I prefer that whenever I have a choice.
Set the locationURI to popup:org.eclipse.ui.projectConfigure
If you need to find the locationURI of any menu press Alt+Shift+F2, then open the menu as usual and click where you want to insert.
You should be using org.eclipse.ui.popupMenus extension point and adding an objectContribution.
Here's a simplified snippet in the plugin.xml that we are using inside of AJDT to contribute to the configure menu. You should be able to use something like this for your project.
<extension
point="org.eclipse.ui.popupMenus">
<objectContribution
objectClass="org.eclipse.core.resources.IProject"
adaptable="true"
id="iprojectcontributions">
<menu
label="%org.eclipse.ajdt.ui.tools"
id="org.eclipse.ajdt.ui.project.tools">
<separator
name="group0">
</separator>
</menu>
<visibility>
<and>
<objectState name="nature" value="org.eclipse.jdt.core.javanature"/>
<not>
<objectState name="nature" value="org.eclipse.ajdt.ui.ajnature"/>
</not>
<objectState name="open" value="true"/>
</and>
</visibility>
<action
label="%convertToAJP"
class="org.eclipse.ajdt.internal.ui.actions.AddAJNatureAction"
menubarPath="org.eclipse.ui.projectConfigure/additions"
id="addajnatureaction">
</action>
</objectContribution>
</extension>
