Dymo labels javascript (API) issue

Question

Hi all.
APEX 4.2
11gR2 XE database.
I'm trying to print labels directly from APEX via a JS library from DYMO (DYMO label framework for javascript).
I would like to fetch the XML for the label layout dynamically from the database instead of fixed assigning this in JS, that way I can store all the templates for labels in the database and fetch the appropriate one for the task I'm doing ).
If I use the fixed code it works fine, code looks like this ( label XML layout is assigned to labelxml variable in the first few lines ) :
function printadres(labeltext )
    try
var labelxml = '<?xml version="1.0" encoding="utf-8"?>\
    <DieCutLabel Version="8.0" Units="twips">\
        <PaperOrientation>Landscape</PaperOrientation>\
        <Id>Address</Id>\
        <PaperName>30252 Address</PaperName>\
        <DrawCommands/>\
        <ObjectInfo>\
            <TextObject>\
                <Name>Text</Name>\
                <ForeColor Alpha="255" Red="0" Green="0" Blue="0" />\
                <BackColor Alpha="0" Red="255" Green="255" Blue="255" />\
                <LinkedObjectName></LinkedObjectName>\
                <Rotation>Rotation0</Rotation>\
                <IsMirrored>False</IsMirrored>\
                <IsVariable>True</IsVariable>\
                <HorizontalAlignment>Left</HorizontalAlignment>\
                <VerticalAlignment>Middle</VerticalAlignment>\
                <TextFitMode>ShrinkToFit</TextFitMode>\
                <UseFullFontHeight>True</UseFullFontHeight>\
                <Verticalized>False</Verticalized>\
                <StyledText/>\
            </TextObject>\
            <Bounds X="332" Y="150" Width="4455" Height="1260" />\
        </ObjectInfo>\
    </DieCutLabel>';
          var label = dymo.label.framework.openLabelXml(labelxml);
          // set label text
          label.setObjectText("Text", labeltext);
          // select printer to print on
          // for simplicity sake just use the first LabelWriter printer
          var printers = dymo.label.framework.getPrinters();
          if (printers.length == 0)
               throw "No DYMO printers are installed. Install DYMO printers.";
          var printerName = "";
          for (var i = 0; i < printers.length; ++i)
               var printer = printers;
               if (printer.printerType == "LabelWriterPrinter")
                    printerName = printer.name;
                    break;
          if (printerName == "")
               throw "No LabelWriter printers found. Install LabelWriter printer";
          // finally print the label
          label.print(printerName);
     catch(e)
          alert(e.message || e);
but when I try to fetch the same XML from a text field on my form it fails with a "getObjectByNameElement(): no object with name 'Text' was found" error which is a custom error from the DYMO library.
I'm unable to find the big difference in the 2 approaches. If I test the variable labelxml by putting it in an alert the value seems fine ( it contains the XML string which is in P11_LABELTEMPLATE which is exactly the same as the static assigned text in the previous example ).
The code then looks like this :function printadres(labeltext )
try
          var labelxml = $v('P11_LABELTEMPLATE'); // This is the dynamic assigment which somehow fails
          var label = dymo.label.framework.openLabelXml(labelxml);
          // set label text
          label.setObjectText("Text", labeltext);
          // select printer to print on
          // for simplicity sake just use the first LabelWriter printer
          var printers = dymo.label.framework.getPrinters();
          if (printers.length == 0)
               throw "No DYMO printers are installed. Install DYMO printers.";
          var printerName = "";
          for (var i = 0; i < printers.length; ++i)
               var printer = printers[i];
               if (printer.printerType == "LabelWriterPrinter")
                    printerName = printer.name;
                    break;
          if (printerName == "")
               throw "No LabelWriter printers found. Install LabelWriter printer";
          // finally print the label
          label.print(printerName);
     catch(e)
          alert(e.message || e);
I'm not sure if this is an APEX or JS question/problem but I hope someone can point me in the right direction.
Regards

Answer 1

Hello Bas,
>> P11_LABELTEMPLATE
There is a possibility that the actual value of P11_LABELTEMPLATE is escaped. Try to use the Session popup window to check the value of the item.
