How Can I access to IPR file value in AnAction Class

Are you sure that "readExternal" is getting called before "run"? Without seeing more of your code there is no way to know. Your implementation for "readExternal" looks correct. But I see "writeExternal" is empty. IDEA tends to call both "read" and "write" often. Having an empty "writeExternal" will result in all your elements disappearing.

I suggest you add a log message at the start of both "readExternal" and "writeExternal" to see if and when they are called.

Plug-In Components Lifecycle
The components are loaded in the following order:

1. Creation - constructor is invoked
Initialization - the initComponent method is invoked
2. Configuration - the readExternal method is invoked (if component implements JDOMExternalizable interface) <- invoked
For module components, the moduleAdded method is invoked to notify that a module has been added to the project
For project components, the projectOpened method is invoked to notify that a project has been loaded
The components are unloaded in the following order:
