Hi there,

I am developing an URCap to control a gripper.

In the ToolbarContribution.java file we have the following code:

```
toolToolbarContribution(ToolbarContext context) {
    context_ = context;
    installation_ = context_.getAPIProvider().getApplicationAPI().getInstallationNode(toolInstallationNodeContribution.class);
    keyboard_factory_ = context_.getAPIProvider().getUserInterfaceAPI().getUserInteraction().getKeyboardInputFactory();
    view_builder_ = context_.getAPIProvider().getSystemAPI().getSoftwareVersion().getMajorVersion() >= 5 ? new ViewBuilder5() : new ViewBuilder3();
  }

```

while in ProgramNodeContribution.java file we have:

```
public toolProgramNodeContribution(ProgramAPIProvider api_provider, toolProgramNodeView view, DataModel model) {
    api_provider_ = api_provider;
    installation_ = api_provider.getProgramAPI().getInstallationNode(toolInstallationNodeContribution.class);
    view_ = view;
    model_ = model;
...
}

```

We have seen that when loading an existing **.installation** file which differs from the default one, in the toolbar the `installation_` variable is not updated, while the one in the programNode is correctly updated.

Does anyone faced this problem? Do you have any suggestion? Are there any differences between the two `getInstallationNode` methods?

Thank you in advance,

Umberto

Probably because the code who set the variable in ProgramNodeContribution has been executed after the .installation file has been loaded ??
