I kept seeing the following exception message when trying to edit an existing FXML file: This version of NetBeans is still in beta and this FXML code completion seems a little buggy. To edit this file in XML directly as shown in the next screen snapshot, I right-clicked on the file's name in the Project browser and then selected the "Edit" option. Note that because I have SceneBuilder installed with my installation of NetBeans, simply clicking on an FXML file always brings that file up in SceneBuilder. ![]() In this case, an "import" tag is recommended. The next screen snapshot shows the FXML raw editor code completion in action. FXML does not have a defined grammar that facilitates any generic XML parser helping with code completion, but fortunately NetBeans 7.3 adds FXML completion to its repertoire (addressing NetBeans Bug 204741). One of the features I missed most when working with JavaFX in NetBeans was the inability to enjoy code completion when using FXML. This is demonstrated in the folowing three screen snapshots. NetBeans 7.3 provides this with the " Invert If" suggestion. There are times when it is helpful to invert a conditional, such as to improve readability of the code. As a side note, this NetBeans annotation has the feel of the annotations discussed in relation to the Checker Framework in the JavaOne 2012 presentation " Build Your Own Type System for Fun and Profit." Applying this annotation to a parameter of the example method shown earlier leads to the hint being displayed. Returning to the NetBeans "null deference hint," another way to demonstrate that new hint in code is via use of the NetBeans annotation. This is a handy feature for following code flow for a certain variable within static code. Clicking on any of the greater-than signs expands possibilities of where that variable is next used. These correspond to places in the code where the highlighted variable is used (class it is used in, method it is used in, and conditional within method it is used in). On the bottom of the above image, there are three greater-than inequality signs ( > following the three respective labels "SevenThree", "processNullValue", and "if (valueStr != null). This is shown in the next screen snapshot.īefore looking at another example of this hint in action, I want to first point out the new code editor Breadcrumbs feature. The "null dereference" hint warns the developer when variables that might be null in certain cases are being dereferenced. NetBeans 7.3 introduces another useful hint with the " null Dereference" hint. I'm a big fan of NetBeans's hints supports as proven by my blog posts on Seven Indispensable NetBeans Java Hints, Seven NetBeans Hints for Modernizing Java Code, Creating a NetBeans 7.1 Custom Hint, NetBeans 7.2 beta: Faster and More Helpful, and NetBeans 7.1's Unused Assignment and Dead Branch Hints. ![]() However, in this post I look at some new features outside of Project Easel that I am happy to see now available in NetBeans. NetBeans 7.3, which is now available in Beta, is already probably best known for its Project Easel features. ![]()
