Hi Leshek,
this is a log trace saying that the FirstStepsApplication class does
not have a public contructor with a Context parameter.
In this case, the default constructor is called followed by a call to
the "setContext" method.
I've added this contructor and updated both source and pages.
However, it shows me that I've missed to update the parent's context
of the application with the component's context:
// Attach the sample application.
component.getDefaultHost().attach(
new FirstStepsApplication(component.getContext()));
It avoids the application to benefit of some component's services.
Thanks again for your report.
best regards,
Thierry Boileau
