Hi,

Try using this condition as

if ((wdContext.currentContextElement().getVa_Input().trim().equalsIgnoreCase(" ")) ||

(wdContext.currentContextElement().getVa_Input()!=null)||

(wdContext.currentContextElement().getVa_Input().trim().equalsIgnoreCase(""))){

//Your code here

}

Hi,

What happens if you do not enter the value and then hit the button?

hi,

if i dont enter value and hit the button it gives a message like" please enter some value " and will not allow user to goahead.

if (wdContext.currentContextElement(). .getVa_comments().equalsIgnoreCase(" ")) {

wdComponentAPI.getMessageManager().reportWarning(

"please enter valid reason");

}
