Problem with naming a custom property "size"

By
I ran into this issue today and thought I'd share:

I created a custom control, and for that custom control I created a few custom properties. One of these properties was unfortunately named "size". There isn't any warning that size would be a bad name for a property, but that causes a problem. It causes a problem because compositeData is just a Map, and size is a method of Map.

So what you wind up getting for some reason, is the entire javascript array instead of the value you are looking for. Something like this:

{size=md, label={columns=2, text=test}, input={dataBinding=null, columns=10}}

I haven't tested it, but I suspect it would be the same with properties named values and clear, among others.

However, if you rename the size property, everything works just fine.

Pass data between XPages and existing LS scripts

By
I'm working on modernizing a fairly hefty application with a lot of existing script libraries which we want to leverage within the XPages environment. Here is a technique that works very well. First, create an in-memory document in SSJS. We can set any input values needed for the back end. Then we pass that document to a LS Agent which can work it's magic using the values set in SSJS and use the same document to return values back to the XPage. Here is how it works in detail:

Rows per page selection: Part 1

By
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....

Quick tip: Convert a number to String in EL

By
I just had a need to do this and a Google search didn't immediately turn up a solution. So I thought for a couple of minutes and came up with this: value="0#{numberVar}" This takes advantage of the way Java auto-converts objects to strings when doing a concatenation. So if your number is 13, Java EL turns this into new String("0"+13), which becomes "013". You can then strip off the leading zero or just parse the string back into a number.
