Question

I have a multivalue field on my document that I would like to remove a value based on the value.

I came up with this:

var doc:NotesDocument = rowData.getDocument();
var item:NotesItem = doc.getFirstItem("ValidProjects");
var a:Array = item.getValues()

for (var v in a)
dBar.info("Before removed V=" + v );

removeFromArray(a,compositeData.ProjectID);
doc.replaceItemValue("ValidProjects",a );

for (var v in a)
dBar.info("After removed V=" + v);


doc.save();


function removeFromArray(arr, val) {
for(var i=0; i<arr.length; i++) {
    dBar.info("Value = " + arr[i] + " Remove = " + val);
    if(arr[i] == val) {
        dBar.info("Removing " + i)
        arr.splice(i, 1);
        break;
    }
   }
}

The removeFromArray is being called successfully and I can see the “Removing 0” message displayed in the debugbar as expected but the array does not change at all and the value is not removed. Any ideas?

Answer 1

Treat the ItemValues as Vector.

function removeFromItemValues(java.util.Vector vector, val) {
      // see http://docs.oracle.com/javase/6/docs/api/java
      vector.remove(val);
      return vector; //Optional
}

Hope that helps
