How to access a dynamic created attribute in a context node?

Question

<i>Hello,</i>
<i>who could help? I can't set a value for a dynamically created attribute which is bind to a table.</i>
<i>My context of the view looks as follow (is defined in NetWeaver):</i>
  - Context
     - Availability (Node)
         - vctxService (Attribute)
         - vctxServiceDesc (Attribute)
         - ... (further predefined attributes)
         - ... (some have to be set dynamically as follows)
<i>Then I have added attributes dynamically in the wdDoModifyView(...) - method, as follows:</i>
for (int i = 0; i < max; i++) {
   // some code to dynamically create table columns
   // adding attributes dynamically
   IWDAttributeInfo attrInfo =       wdContext.nodeAvailability().getNodeInfo().      addAttribute("vctxAvailability_" + i, "ddic:com.sap.dictionary.string");
   tv.bindText(attrInfo); // bind to TextView in table
<i>In the method onPlugFrom... I tried to set the values for the attributes "vctxAvailability_ + i" as follows:</i>
for (int i = 0; i < max; i++) {
   IAvailabilityElement newAvailNodeElement =     wdContext.createAvailabilityElement();
   // some values will be set for the
   // predefined attributes of AvailabilityNode
   // newAvailNodeElement.set...( value );
   // newAvailNodeElement.setVctxService( xy.getServ() );
   // now the values of dynamically created and added
   // attributes in AvailabilityNode will be added
   // THIS DOESN'T WORK
   newAvailNodeElement.setAttributeValue    ("vctxAvailability_" + i, "value" + i);
<i>It would be great if someone could help me.
Thanks in advance.
Kind regards,

Carsten,
Here is a sample code that creates context attributes dynamically and also sets values:
//Creates a node
IWDNodeInfo nodeInfo = wdContext.wdGetAPI().getRootNodeInfo().addChild("TestNode", null, true, true, false, true, false, true, null, null, null);
//If you want to bind the node to a model node then the
//second argument to the above method should be the
//model class.
//Creates an attribute under the node just created.
IWDAttributeInfo testAttrib = wdContext.wdGetAPI().getRootNodeInfo().getChild("TestNode").addAttribute("testAttrib", "ddic:com.sap.dictionary.string");
IWDNodeElement testNode = wdContext.getChildNode("TestNode", IWDNode.LEAD_SELECTION).getCurrentElement();
IWDNode testNode2 = wdContext.getChildNode("TestNode", IWDNode.LEAD_SELECTION);
//Now you can bind testNode with the Model Node
//You can also set a value to the newly created attribute
testNode.setAttributeValue("testAttrib", new String("Value"));
Hope this helps.
