DataClass setAttribute NPE

Smart GWT Technical Q&A

This code presumes that value is never null. If I want to clear an attribute (ie, set it to null) then these methods will blow up. There should be an null check.

    public void setAttribute(String property, DataClass value) {
        JSOHelper.setAttribute(jsObj, property, value.getJsObj());
    }

    public void setAttribute(String property, BaseClass value) {
        JSOHelper.setAttribute(jsObj, property, value.getOrCreateJsObj());
    }

Good point - we’ll make sure this change is made for the upcoming release.
