workbench.xmi is not written in my e4 app [message #1034414]

I am trying to implement persistance for my e4 app.
What could be the reason for my app for not to create/read the "workbench.xmi"

What I did:
I removed -persistState - @Inject@Named(E4Workbench.PERSIST_STATE) is true.
I removed -clearPersistedState - @Inject@Named(E4Workbench.CLEAR_PERSISTED_STATE) is false.

Are you sure you are not cleaning the workspace in your launch
configuration? Please also note that those values can maybe be found in
your plugin.xml where you configure your product!

Hey Tom:

I am injecting the following:

    @Inject
    @Named(E4Workbench.PERSIST_STATE)
    private boolean persistState; //true

    @Inject
    @Named(E4Workbench.CLEAR_PERSISTED_STATE)
    private boolean clearPersistedState; //false

I unchecked RunConfiguration> Main > Clear (Workspace Data)
I unchecked RunConfiguration> Configuration> Clear te configuration area before closing

so I asume, that the workbench is not cleared.

I found, that the workbench.xmi is created in the folder I wrote down in "Runtime Configuration > Workspace Data" at application runtime,

but it is deleted, when the app is closed again.

Does it make any sence?

I had a similar issue to yours. The trick is that there are 3 different places to modify:

1) Run Configurations/Arguments tab: Remove -clearPersistedState from your Program arguments textbox.
2) Run Consigurations/Main tab: Uncheck Clear
3) plugin.xml: Remove this element:

<property name="clearPersistedState" value="true"></property>

I fixed number three in the tooling so if you generate a new sample e4 app you won't get the 3) by default.
