Fixing FontAwesome for Windows 10

I ran into an issue with FontAwesome a few months back, where a NoCache header was being injected at the server and FA was broken for any partial refresh. I convinced the admin to reverse that setting and all was well until last week... We had some users who were not getting any icons to appear. Ever. We tracked it down to a new Windows 10 setting for IE11 which disallows untrusted fonts. Since we do not set security protocols for our users, and there is no chance of ever convincing those admins to change this policy that they explicitly turned on, I had to find a new solution. I did some searching and it turned out to not be too difficult. First, here is the original implementation. The theme: <control> <name>Icon.Search</name> <property mode="override"> <name>tagName</name> <value>i</value> </property> <property mode="concat"> <name>styleClass</name> <value>fa fa-search&

Rows per page selection: Part 2

I was asked to create a control that would allow users to select the number of rows per page in a view/repeat control (the application uses both). It seemed simple at first, but I ran into a few issues that I thought I'd share the solutions to. Problem 2: When the page refreshed, the combobox value always reverted back to the default It turns out that the Integer value stored in the viewScope doesn't get run through the converter back to a string before being compared to options. I needed a way to calculate the option values so that they would be Integers. This is also not the first time I've run into issues where I need a value to be of a different type, and I see questions like this on StackOverflow from time to time. I attempted a few minor things before I realized I needed to break out my old stand-by, the GetMap . The GetMap is just a fake Map implementation that takes the key and transforms it or uses it to look up some other value. In this case, we are doing the f

Rows per page selection: Part 1

I was asked to create a control that would allow users to select the number of rows per page in a view/repeat control (the application uses both). It seemed simple at first, but I ran into a few issues that I thought I'd share the solutions to. First, lets start at the beginning. I went through the relevant design elements and set row="#{viewScope.tableRows}" , and I created an xp:comboBox with value="#{viewScope.tableRows}" and added items for 20, 30, 50, and 100, and I assigned it an onChange event handler that did a partial execution and partial refresh of a div containing the combo box, pager and the table. Then I started fixing all the problems. Problem 1: The combobox value was a string, but the rows parameter requires an integer. This was causing IllegalArgumentException / java.lang.String incompatible with java.lang.Integer. I added a NumberConverter, but this only slightly changed the exception message to java.lang.Long incompatible with java.lang.
