Did you want to do validation or just have something like a mouse over or tooltip text? We did a validation that is triggered off the complete button which we had to override the completeButton.jsp to insert a called to a javascript. That javascript is where its all done:
completeTask.setButton(true);
//completeTask.setEnabled(true);
completeTask.setTitle("Complete Task");
completeTask.setDesc("Complete Task");
completeTask.setEnabled((!myNmWorkItem.isCompleted() && !myNmWorkItem.isSuspended() && myNmWorkItem.isMine()));
//10-24-2024 addition - Parent JSP page must contain this validtion script
completeTask.setOnClick("validate_Complete()");
This calls the validate_Complete() function where in my case, I can checking to see if comments were entered for a variable called comments and that a checkbox was checked:
function validate_Complete()
{
var c=document.getElementsByTagName("textarea")
var comment;
for (var k=0; k<c.length; k++)
{
if (c[k].name.indexOf("comments")!=-1)
{
comment=c[k];
break;
}
}
if (IsEmpty(comment))
{
alert("Please enter comments");
return false;
}
c=document.getElementsByTagName("input");
for (var k=0; k<c.length; k++)
{
if (c[k].name.indexOf("Acknowledge")!=-1)
{
if (!c[k].checked)
{
alert("Please check the 'Acknowledge' checkbox to accept agreement.");
return false;
}
break;
}
}
return true;
}
You can also do this in Java code with a transition expression but that runs on server side after the button is clicked and you would trip a WTException with a helpful message.
