Hi

Apart from the previous reply ,Optimum solution for this is create a dedicated view and window ,define one method in Component Controller with String and IWDWindow parameter (which take care of LifeSpan of dialog window and Messages including validation feild) and called it throughout the component.So just pass the validation message which will change in each case remaining things will same

Hi,

it's possible for you to validate the field after entering values and before submition of form.

Even you can open one exrternal window with the help of IWDWindow and pass error parameter which you can display.

IWDWindow window = wdComponentAPI.getWindowManager().createModalWindow(windowInfo);

window.setWindowPosition (300, 150);

window.show();

In Web Dynpro java you can validate the field viause node's attirbure value attached to it and display error msg using MessageManager and you can use message pool too.
