Hi Everybody,

I'm new to eclipse plug-in development. I have created a plug-in and it has some configurations - saved as preferences-. I want to export and import these preferences using the eclipse export preferences dialog.

I tried using org.eclipse.ui.preferenceTransfer extension point but nothing appears in the preferences list when I open Export preferences dialog. Here's how I used it:

<extension point="org.eclipse.ui.preferenceTransfer">
      <transfer id="com.anas.assets.tool.preferences.transfer"
            name="Tool Configurations">
         <mapping scope="instance">
            <entry node="com.anas.assets.tool">
               <key match="prefix" name="com.anas.assets.tool.">

Any ideas what may be the problem? Should the node in <entry node="com.anas.assets.tool"> match a specific object ID in the plug-in? I used the plug-in ID as in the Manifest file.

Any samples of using this extension point or providing similar functionality is appreciated.

The key com.anas.assets.tool. is causing the problem. I don't know why but when I changed it to more specific key (com.anas.assets.tool.colors) it worked fine.

I don't know why?!!! but it finally worked.

Appreciate if someone can clarify why this may happen.
