EventHoverHTMLEvent - GWT Compiler Warning - Referencing deprecated class

[ex70375]

hi isomorphic,

i get this gwt compiler warning

Warnings in 'jar:file:/..../smartgwtpower-4.1p/lib/smartgwtpower.jar!/com/smartgwt/client/widgets/calendar/Calendar.java'
Referencing deprecated class 'com.smartgwt.client.widgets.calendar.events.EventHoverHTMLEvent'

with every build. As you can see -in the ant task javac- I just use the deprecated method Page.RegisterKey and not the class EventHoverHTMLEvent. In my application I use the class EventHoverHTMLEvent never directly.

This is just an information to you. I have no problem with that.

i used: Isomorphic SmartClient/SmartGWT Framework (v9.1p_2014-03-11/PowerEdition Deployment 2014-03-11)

Best regards,

[Isomorphic]

There do not appear to be any internal references to this class.

If you can show how to get a deprecation warning without referencing this class in your own code, please let us know.

[ex70375]

you use the deprecated EventHoverHTMLEvent code in your deprecated addEventHoverHTMLHandler code :-)

please have a look at line 3287 within com.smartgwt.client.widgets.calendar.Calendar.java at build v9.1p_2014-03-11/PowerEdition Deployment 2014-03-11

    public HandlerRegistration addEventHoverHTMLHandler(com.smartgwt.client.widgets.calendar.events.EventHoverHTMLHandler handler) {
        if(getHandlerCount(com.smartgwt.client.widgets.calendar.events.EventHoverHTMLEvent.getType()) == 0) setupEventHoverHTMLEvent();
        return doAddHandler(handler, com.smartgwt.client.widgets.calendar.events.EventHoverHTMLEvent.getType());
    }

I think that's the problem

[Isomorphic]

That would be why addEventHoverHTMLHandler() is also deprecated.

Don't call this (deprecated) method and you will not receive deprecation warnings.

[klop]

My build produces the same warning, though there is no reference in my application to com.smartgwt.client.widgets.calendar.anything.

Using gwtc in GWT 2.5.1.

Using SmartClient Version: v9.1p_2014-03-03/Pro Deployment (built 2014-03-03)

[Isomorphic]

We're not reproducing that. Try creating a standalone test case.

[ex70375]

steps to reproduce:
1) Download and unzip Smart GWT Power Edition (2014-03-11 nightly)
2) Import BuiltInDS example into eclipse
3) change build.xml:
3a) inside task "javac": change to source="1.6" target="1.6" and insert <compilerarg value="-Xlint:deprecation"/>
3b) inside task gwtc: insert <arg value="-strict" />
3c) insert gwt.sdk path (optional)
5) run the build task in eclipse

as you can see, the method is used nowhere!

I am still not able to reproduce this. I've tried both with power edition and the enterprise eval. What version of GWT are you using? Is it customized at all?

did you delete your gwt-unitCache directory before? I found out that the message only appears if the directory has been recreated.
