SmartGWT Version: Smart GWT Pro Edition 4.0p (2013-12-18 nightly)
We are migrating to SmartGWT Pro 4.0 and have encountered a NullPointerException in the com.smartgwt.client.data.Criterion class. In our case the this.getCriteria() call returns null, which causes the "this.getCriteria().length" call in the else block to throw a NullPointerException.

if (opString != null && opString.equals(OperatorId.AND.getValue())) {
appendToCriterionList(c);
} else {
if (this.getAttributeAsObject("value") != null || this.getCriteria().length != 0) {
Criterion thisCopy = new Criterion(this);
JSOHelper.deleteAttributeIfExists(jsObj, "fieldName");
JSOHelper.deleteAttributeIfExists(jsObj, "value");
Criterion[] criteriaList = { thisCopy, c };
buildCriterionFromList(OperatorId.AND, criteriaList);
} else {

}
}
}
public Criterion[] getCriteria() {
JavaScriptObject[] jsCriteria = JSOHelper.getAttributeAsJavaScriptObjectArray(getJsObj(), "criteria");
if (jsCriteria == null) return null;
Criterion[] criteria = new Criterion[jsCriteria.length];
for (int i = 0; i < jsCriteria.length; i++) {
criteria[i] = Criterion.getOrCreateRef(jsCriteria[i]);
}
return criteria;
