Hello

If you have followed the above link, then its well and good.

I ll try to simpify it. Follow these steps

1. In the message pool of your DC/project declare a Message Key 'Missing_Input' having Message Type 'error', Message Text 'Please enter the '.

2. In the action handler of your 'Save' button write the following code

String name = wdContext.<get the value>;

if(null == name || "".equals(name ) || "0000000000".equals(name ) || name .length() <= 0)

{

IWDAttributeInfo nameInfo = wdContext.node<name>().getNodeInfo().getAttribute("<attribute name>");

msgMgr.reportContextAttributeMessage(wdContext.current<node name>Element(),nameInfo ,IMessage<ComponentName>Component.MISSING__INPUT,new Object[] { "<Name of attribute>" }, true);

}

Try this. I hope it helps you.
