I found a problem in the org/netbeans/modules/viewmodel/TreeModelNode.java at line 2127 in the updateShortDescription the method model.getValueAt is called passing the JTooltip instead of the Node Object. This is going to cause a Illegal Cast Exception in our client code. Of course we will protect our code checking the instance of the object before to cast it, but I think this method is used improperly in the case. Here the code. private String updateShortDescription() { try { javax.swing.JToolTip tooltip = new javax.swing.JToolTip(); String sd = null; try { tooltip.putClientProperty("getShortDescription", object); // NOI18N Object tooltipObj = model.getValueAt(tooltip, id); if (tooltipObj != null) { sd = adjustHTML(tooltipObj.toString()); } return sd; } finally { // We MUST clear the client property, Swing holds this in a static reference! tooltip.putClientProperty("getShortDescription", null); // NOI18N synchronized (properties) { properties.put (id + "#shortDescription", sd); } } } catch (UnknownTypeException e) { // Ignore models that do not define tooltips for values. return null; } } Thanks -Paolo
