look in -->C:\Program Files (x86)\IBM\Lotus\Notes\Data\IBM_TECHNICAL_SUPPORT

might be different based upon your install, but sort by date and look for the stack trace in either the console log or the exec file and provide that.

Seems to be an issue with setting the array value.

Does error CLFAD0134E: Exception processing XPage request mean anything?

However, when you look at the crash it states:

Error while executing JavaScript action expression
put(int index,FBSValue value) not supported in JavaWrapperObject

I assume the put(int index) is the attempted replace of the indexed element for the field.  Is my coding correct?  Is there another way to replace an element in an existing multivalue field?  Currently I'm using

            catStatus[bci] = 'CO';  where catStatus is the multivalue field, and bci is set to 1. 

Jst for grins I also changed the code to catStatus[1] = 'CO  and it also crashed.

Any other suggestions?
      

Don't know what you mean by the "exec file"  Where's that?

This should sove your probliem; just one solution.

var Field_Arr = new Array(document1.getItemValue("Fieldname"))
Field_Arr[0] = "new Value";
document1.setValue("Fieldname",Field_Arr)

I replaced my code with

print ("found bci match");
print ("catStatus = " + catStatus[bci]);
var Field_Arr = new Array(doc.getItemValue("Status"))
Field_Arr[0] = "new Value";
print ("field array is now assigned " + Field_Arr[0]);
doc.setValue("Status",Field_Arr)
print ("past crash");

I get this far in the log

selected BC is 20110155RAS-1
09/10/2013 08:25:38 AM  HTTP JVM: length of barcodes is 5
09/10/2013 08:25:38 AM  HTTP JVM: bci = 0
09/10/2013 08:25:38 AM  HTTP JVM: found bci match
09/10/2013 08:25:38 AM  HTTP JVM: catStatus = Avail

and this error

Error undefined (Error calling method 'setValue(string, Array)' on an object of type 'lotus.domino.local.Document [Static Java Interface Wrapper, lotus.domino.local.Document: lotus.domino.Document]')

Shouldn't if be:

doc.replaceItemValue(...)

rather then doc.setValue()

?

Of course replaceItemValue 

The problem appears to be my not setting the array.  Your code

var Field_Arr = new Array(doc.getItemValue("Status"));  solved it.

I was just setting var Field_Arr = doc.getItemValue("Status");

Many thanks for the help!
                  

I battled with this issue, with much the same results. I posted a question to StackOverFlow with teh question which is most effecient doc.getItemValue("Field") or getComponent("Field").getValue() The answer was NEITHER

Here is a link to the answer:

http://stackoverflow.com/questions/18303862/which-is-the-most-efficient-way-to-access-the-value-of-a-control

If working with the document you must use getItemValue(), however, the most effecient way to access the backend document is by using the NotesDataSource object set to document1 by default but might be different and then use document1.getValue("Field")

working directly with the array in within the NotesDocument or the DataSource does not work in either JS or LS. I believe the most effecient method would be were document1 is the datasource

var myArray:Array = document1.getValue("SourceArray");

myArray[3] = "Some Value";

document1.setValue("SourceArray",myArray);

I have a process that cycles through a bunch (a technical term) of access to the backend document and I noticed an improvement in speed when I accessed the fields through the getValue in the datasource rather than getItemValue in the document. I am no expert in how the XPages works under the covers but the explaination in the stackoverflow make a lot of sense. I went through my code and change most of it to access the dataSource rather than the doc (got to love the search of the source code in XPages). I found a few places where I still needed to use getComponent (whcih if I read it right should actually be your last choice) or doc.getItemValue.

Hi, Robert.

As for me, I am also testing the related barcode reader these days. Do you have any ideas about it? Or any good suggestion? I am totally a green hand on this barcode reading field. Any suggestion will be appreciated. Thanks in advance.
