How to check if dynamic multiline textfield is empty
Hello everyone.
My question is quite simple although I can't find a good answer... I want to be able to check whether a multiline textfield is empty or not.
I tried this, but without result.
If (my_txt.text! = "")
{
do something;
}
If (my_txt.text.length! = 0)
{
do something;
}
Non of these work. I searched other forums and I realized that it could operate only on the single line textfield. But what about multiline?

function stripWhiteF(s:String):String {}
While (s.substr(s.Length-1) is"" | ") s.substr(s.Length-1) == '\r ' | s.substr(s.Length-1) == "r" | {s.substr(s.Length-1)=="\t")}
s = s.substr(0,s.length-1);
}
return s;
}

How to check if an input field is empty or without signs
Well, then I'm doing a connection. How can I check to see if something is typed in all in the chain.
You can test the length of its text property.
If (String (tField.text) .length > 0)... There is something typed into it.
You can exit without cast a string, [if(tField.text.length > 0)...] but I show for the sake of form.

Hi friends,
Jdev: 11.1.1.7

I need to display the ToolTip on mouseover this link. To display the ToolTip, I used the popup. How to find the dynamic ID inside the af: foreach in java.
If I bind the comonent, it does not work inside foreach.
Try this way, root.findComponent("r1:it2"); it is in taskflow. On popufetchlistener you call a method to get the id of the component to get the book desc.

Hi, I have "roll-over" event listener and I wish that only works with music videos (without textfields etc.). I would write something like this:

This does not work properly.

iPod Classic stopped display work. Work displayed in iTunes. Updated iTunes to 12.4 but did not help. I can see how to check and uncheck "Display work" in iTunes but not how on the iPod as others have suggested. Need to perhaps restore and recharge.
Long ago with including works on devices was optional, and you can sometimes fix cache work on a device by not including and then add it again. This choice has long since disappeared. A complete restoration and reloading is now the only method to recreate the cache.
