Bug in node - g

[mathias]

version: v9.1p_2014-11-24/Pro Deployment (built 2014-11-24)


I just upgraded to latest nightly, and our reports code, which has been static for like 2 years, broke.

We have a method to manually set group headers in a grouped grid. like in the code below. The TreeNode method GetIsGroupSummary() now throws a NullPointer. The node is not null (we've debugged), it's something inside the node code that throws the exception.

Our method:

private String findGroupSummaryField(Tree tree, TreeNode parent, String attribute) {
        for (TreeNode node : tree.getChildren(parent)) {
            if (node.getIsGroupSummary()) { <<<< NULLPOINTER
                return node.getAttribute(attribute);
            }
        }
        return null;
    }

Some ideas on how to proceed would be appreciated.

Edit: ran it with try-catch around just to get some text out in deployed mode:

(TypeError) line: 2589 column: 128 sourceURL: http://localhost:8080/xxx/E3FC7492BA...510.cache.html __gwt$exception: : null is not an object (evaluating 'oVb(d.j,'isGroupSummary',true).b') ; com.google.gwt.core.client.JavaScriptException: (TypeError) line: 2589 column: 128 sourceURL: http://localhost:8080/xxx/E3FC7492BA...510.cache.html __gwt$exception: : null is not an object (evaluating 'oVb(d.j,'isGroupSummary',true).b')

...reverted back to the version we ran previously,

4.1-p20140608.

Works fine again, no null pointer exceptions. So there's something wrong here.

We see the problem and will update this thread when we've decided how to resolve it.

The fix should be in the next nightly builds of SGWT 4.1p and nwer.
