GWTP & Singleton

[Лешик Иванов]

I have simple presenter. Announce the call to the class of singleton

private RandomString randomString = RandomString.getInstance();

When assembling maven I have error

[INFO]             [ERROR] Error injecting by.gwttest.client.client.application.packet.PacketPagePresenter$MyProxy: Unable to create or inherit binding: No @Inject or default constructor found for by.gwttest.client.client.application.packet.PacketPagePresenter$MyProxy

RandomString ...

    private RandomString() {

    }

    private static class RandomStringHolder {
        private final static RandomString instance = new RandomString();
    }

    public static RandomString getInstance() {
        return RandomStringHolder.instance;
    }
...

With what it can be connected? Without declaring RandomString project going

Can you provide more info? Can you share the presenter how you coded it and where in it are you creating the randomString. The error can come due to many reasons- primarily if the binding fails. Are you sure you have binded the presenter correctly in presenter module? If yes, there will be some other error causing the binding the fail. Is this the full error stack or was there more to it?

[Christian Goudreau]

That kind of stack trace happens most of the time when the present isn't correctly bound or written, could you provide the presenter, the view and the gin module binding?

Error was in this code

	private String convertMStoTime(long millis) {
		//return null;
		 return String.format(
		 "%02d:%02d:%02d",
		 TimeUnit.MILLISECONDS.toHours(millis),
		 TimeUnit.MILLISECONDS.toMinutes(millis)
		 - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS
		 .toHours(millis)),
		 TimeUnit.MILLISECONDS.toSeconds(millis)
		 - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS
		 .toMinutes(millis)));
	}

TimeUnit.MILLISECONDS.toHours

dont't realese in GWT

Damn, must have been hard to debug! Your IDE didn't warned you about the class being not compatible with GWT?
