problem upgrading to smartgwt 4.1, toolstrip throws exception

[mathias]

Hello, as mentioned, trying to upgrade my project to 4.1 from 3.1.

I have a code segment that adds buttons to a toolstrip and adds separators between them, always worked fine:

public void addToolBarItem(CrudToolStripButton button){
        try {
            button.setShowFocused(false);
            button.setCanFocus(false);
 >>>>>>           if(toolStrip.getMembers().length >0){
                toolStrip.addSeparator();
            }
            toolStrip.addButton(button);
            toolbarItems.add(button);
        } catch (Exception e) {
            e.printStackTrace(); 
        }
    }

but when i now shifted my jars to 4.1, i get a weird exception, complaining about the marked line in my code segment above.

I have no idea what is is, pointers much appreciated. Stack trace below:

Hey guys,

any chance of a response to this? Would be great to hear you're looking into it. We use that method in quite a few places in our app.

as one of the other thread headers say: "Exception in method getMembers() class ToolStrip" is the issue.


There are two other threads on the same topic, so i'm not the only one:

This is already being looked into.

This problem is proving a bit elusive, but we are continuing to investigate.

Hello, I have the same problem:

toolStrip.getMembers() fails with java.lang.AssertionError

you posted that promblem was fixed in 4.1p release, but i download latest build (2014-06-07) and it still fails

A test case constructed from the code above no longer crashes. Let us know if you can produce a ready-to-run, minimal test case where there is still an issue.
