is Call.xml reserved?

Hi,

When I create a new layout named as “Call.xml” and add this page to my workplace I receive the following error (I tried with different projects/workplaces):


java.lang.StringIndexOutOfBoundsException: String index out of range: -1

Is Call.xml a reserved page :?: Following is my code to add this page to my workplace (no need to mention that I add all other pages similarly and get no error!):


final MFWorkplaceInfo inf = new MFWorkplaceInfo(EMPTY_PAGE);
final MFWorkplaceTopic topic = new MFWorkplaceTopic ("sampleTopic", inf, "sampleTopic");
final String img = "../SampleProject/images/sampleImage.gif";
final MFWorkplaceTreeNode subnode = new MFWorkplaceTreeNode (MFWorkplaceConstants.TYPE_CIPAGE, "samplePage", img, img, "/SampleProject/Call",true, true);
final TREECollection tc = topic.getTree();
tc.addTopNode(subnode, true);
tc.openAllNodes();
