Hi,

Change the selection cardinality of the node bound to the DropDownBy<Key/Index> UI element to 1...1.

Hi,

Set the selection cardinality of the node bound to your drop down by index to 1..n, so that the empty row is removed.

Why 1:N and not 1:1?

public void wdDoInit()

{

//@@begin wdDoInit()

wdContext.currentContextElement().setName("12345");

IPrivateTestWdView.ITable1Node node1=wdContext.nodeTable1();

IPrivateTestWdView.ITable1Element ele1;

for(int i=0;i<4;i++)

{

ele1=wdContext.nodeTable1().createTable1Element();

node1.addElement(ele1);

}

IWDAttributeInfo attributeInfo_skillarea = wdContext.getNodeInfo().getChild("table1").getAttribute(IPrivateTestWdView.ITable1Element.COL3);

ISimpleTypeModifiable skillarea_Type = attributeInfo_skillarea.getModifiableSimpleType();

IModifiableSimpleValueSet valueSet_skillarea = skillarea_Type.getSVServices().getModifiableSimpleValueSet();

valueSet_skillarea.put("Select","Select");

valueSet_skillarea.put("ZOBJID","ZQKTEST");

IPrivateTestWdView.IDropdown1Node dnode=wdContext.nodeDropdown1();

IPrivateTestWdView.IDropdown1Element dele;

dele=wdContext.nodeDropdown1().createDropdown1Element();

dele.setAttr1("123");

dnode.addElement(dele);

dele=wdContext.nodeDropdown1().createDropdown1Element();

dele.setAttr1("456");

dnode.addElement(dele);

dele=wdContext.nodeDropdown1().createDropdown1Element();

dele.setAttr1("789");

dnode.addElement(dele);

//@@end

}

this coding is for drop down by index.try this,Also use try catch block.
