MWLUG Slides – AD114 Take Your XPages Development to the Next Level

In this session at MWLUG 2015, Paul Calhoun and I dug into a number of features already available in XPages, but not as widely used.

We only had time to cover half of the sections, but the full set of slides is available here

Topics include:

  1. Application Responsiveness (primarily JSON RPC)
  2. SSJS Tips
  3. Modifying Component output
  4. Java Tips
  5. Custom Controls (including dynamic field binding to make reusable fields)
  6. Resources for learning more
  7. Debugging Tips
  8. Event handlers
  9. Dojo

Updating Select2 Styling to Match Bootstrap Fields

Select2 is an awesome jQuery plugin to enhance the functionality of combo boxes. But if you implement it in an application with a Bootstrap UI, you’ll notice that the styling is not consistent. In this post, I’ll show how to make the styling of Select2 fields consistent with other fields on the form.

Bootstrap Default Styling

Here’s an example of a simple Bootstrap form, including two combo box fields. The styling is very consistent across all of the fields.

Select2 A - Default Drop-Down

Select2 Default Styling

Once I implement Select2 and add the code to initialize combo boxes as Select2 fields, they styling changes. The width and internal padding and line spacing are not consistent with other bootstrap fields. (Click image to enlarge in order to see the difference more clearly.)

Select2 B - Default Select2 Style

Consistent Styling

Fortunately, by inspecting a standard bootstrap field either in the bootstrap CSS or in the browser’s developer tools, I can see the styles in use and replicate them for a more consistent look.

Select2 C - Consistent Select2 Style

Here is the CSS required to make it happen:

.select2-container {

.select2-container a.select2-choice {
  font-size: 14px;
  height: 38px;
  padding: 8px 12px;
  line-height: 1.42857;

.select2-container .select2-choice .select2-arrow {

The first rule makes the field width use 100% of the size of its container, as bootstrap fields do.

The second set of rules sets the font and field styling to make them consistent.

The third rule vertically centers the drop-down arrow for the larger field.

Fixing an Issue with Glyphicons with a Bootswatch Theme in XPages

In this post, I’ll describe an issue that I had with glyphicons when using a Bootswatch theme in XPages and how to fix it.

When you use a Bootswatch theme, you do not need to separately include the original
bootstrap.css file. In fact, it would be inefficient to do so, because the styling is provided by the Bootswatch CSS file.

When adding any additional Javascript libraries or CSS to an XPages application, I generally put them in their own folder under WebContent and then include the library or stylesheet via the application theme.


However, I noticed an issue when doing this recently. The Bootswatch theme styling loaded fine, but glyphicons on the page were
not displayed properly; the unrecognized font character symbol was displayed instead.

Glyphicons are loaded as a font (much like Font Awesome), so I looked through the stylesheet to see how the font was included. As you can see, the reference is relative to the current directory, assuming a standard Bootstrap directory structure.

@font-face {
  font-family: 'Glyphicons Halflings';
  src: url('../fonts/glyphicons-halflings-regular.eot');
  src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff2') format('woff2'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons_halflingsregular') format('svg');

There are two ways to go about fixing this:

  1. You can update the font references to be relative to the actual directory structure.
  2. Much more simply, you can move the bootswatch CSS file into the css directory under the bootstrap directory so the relative font file references work without being modified.
