rmarkdown automatically loads the hyperref package. You can't load it again with conflicting options.

You can change its settings with \hypersetup{...}:

I copied your code into my Eclipse IDE. A class was missing, so I couldn't see what your GUI looks like.

So I created this GUI.

I left off the loyalty card button.

Oracle has a helpful tutorial, Creating a GUI With Swing. Skip the Learning Swing with the NetBeans IDE section.

I use the model-view-controller (MVC) pattern when creating a Swing application. The name implies that you create the model first, then the view, then the controller.

The application model consists of one or more plain Java getter/setter classes.

The view consists of one JFrame, one or more JPanels, and Swing components.

Each Action or ActionListener class makes up the controller. There's usually not one controller to "rule them all".

The first model class I created is the Item class. The Item class holds a name and a price. The price is specified in pence. Using an int field to hold the price makes the calculations easier. I translate the pence into pounds when displaying the prices.

The second model class I created is the VendingMachineModel class. The VendingMachineModel class holds a java.util.List of items, a java.util.List of coins, an int balance field, and an int change field.

Your view was easy to follow and well structured, so I don't have a lot of comments here. I used a ButtonGroup to limit the JRadioButtons to one selection.

Don't make all the Swing components class fields. It's confusing for readers of your code. Class fields should only be used for fields needed in more than one method.

Order your methods within a class from the most important method to the least important methods. This makes the code easier for people to read and understand.

I used lambda expressions for all the JButtons except the purchase button. That ActionPerformed method was too large for a lambda expression, in my opinion, so I created a PurchaseListener class.

Here's the complete runnable code. I made the additional classes inner classes so I could post the code as one block.

I've figured out what caused the problem:

There was a linebreak \n in one of the cells of "tot_cost3" causing the table format to break apart when using pack_rows or collapse_rows!

LaTeX, somehow shows surprisingly high tolerance on that, which is quite unusual. As a result, it won’t throw an error if you are just using kable to make some simple tables. However, when you use kableExtra to make some advanced modification, it will start to throw some bugs

from Hao Zhou's "Create Awesome LaTeX Table with knitr::kable and kableExtra" (http://haozhu233.github.io/kableExtra/awesome_table_in_pdf.pdf) Tutorial provided me with the hint to look for formatting issues in the table content itself...

The property is called "sonar.coverage.jacoco.xmlReportPaths" (note the "s"). Your text and your code sample specify different property names and values for this. Figure out where it is and use that. Different build configurations might put it in a different place. Look in the workspace of your build to see where the file was created.

There's probably a way of doing this using reflection — but that should only be a last resort. (It's likely to be long-winded, fragile, slow, hard to maintain, and insecure. Handy for frameworks, plug-ins, and compiler tools; but for general programming there's usually a better approach.)

One approach here would be to store a reference to the function it should call, in addition to the name.

You could use a simple class like this to store them:

Problems and corrections for your XSD and XML follow.

Your XSD has a number of problems:

1. XML and XSD are case sensitive, so change xs:Sequence to xs:sequence.
2. closes the element before including the intended following xs:complexType definition. This happens again with availablecolors.
3. You have missing xs:sequence elements under xs:complexType.
4. It fails to accommodate multiple link elements.
5. It is missing a declaration for tophp.

You can not use category to filter in pages = Page.objects.filter(category). It is not clear for what field you would filter the page, you thus need to specify the field that links to the category, and filter with:
