SectionStack.create() causes warning messages in hosted mode shell

[tomhj]

I'm experimenting with SmartGWT after downloading the 1.0b1 release yesterday - so far it looks very nice.

I coded up a prototype which uses among other things a SectionStack. It seems to behave as expected, but I see a bunch of warning messages on the hosted mode development shell window:

Malformed JSNI reference 'constructor'; expect subsequent failures.

The detailed stack trace shows:

[WARN] Malformed JSNI reference 'constructor'; expect subsequent failures
java.lang.NoSuchFieldError: constructor

My code looks like this:

        SectionStack filtersStack = new SectionStack();
        filtersStack.setHeight100();
        filtersStack.setWidth100();
        filtersStack.setVisibilityMode(VisibilityMode.MULTIPLE);
        
        SectionStackSection findTerm = new SectionStackSection("Find Term");
        findTerm.setExpanded(true);
        findTerm.addItem(new Label("find term stuff goes here..."));
        filtersStack.addSection(findTerm);
        
        SectionStackSection hideDocuments = new SectionStackSection("Hide Documents");
        hideDocuments.setExpanded(true);
        hideDocuments.addItem(new Label("hide documents goes here..."));
        filtersStack.addSection(hideDocuments);
        
        SectionStackSection filterByDate = new SectionStackSection("Filter by Date");
        filtersStack.addSection(filterByDate);

        hLayout.addMember(filtersStack);

I'm running GWT 1.5.3 on a Windows XP machine if that matters.

Any ideas?

thanks,
Tom

Yeah, this is something that I'm aware of and also the reason behind it. Hopefully the next release will have it resolved but you can safely ignore it for now. Besides being annoying and something that is specific to running in hosted mode, it has no negative consequence.
