Highlight duplicates in a table

kclark

Example showing how to highlight duplicate data in a table using a highlight rule and an ArrayList.<br />
<br />
I create an ArrayList in the beforeOpen of my data set.

array = new java.util.ArrayList();

<br />
Then I had to store the values of the column I wanted to check for later in the onFetch()

array.add(row["QUANTITYORDERED"]);

<br />
I also had to store this ArrayList as a global persistent variable from afterClose()

reportContext.setPersistentGlobalVariable("array", array);

<br />
Now that all the values are stored I can use the following scripts as expressions from the highlight rule UI.

var array = reportContext.getPersistentGlobalVariable("array");
var first   = array.indexOf(row["QUANTITYORDERED"]);
first;

<br />
Not Equal to

var array = reportContext.getPersistentGlobalVariable("array");
var last   = array.lastIndexOf(row["QUANTITYORDERED"]);
last;
