use-when

[Pierre Smits]

Hi all,

I want to have a button only visible (with use-when on a field widget in a
form) in an overview when following conditions are met:

   1. when thruDate is null or empty
   2. when thruDate is great or equal to now.

I can get the first one going, but the second and thus the combo not.

Who can help me out?

Regards,

Pierre

Try this for second condition use-when="${thruDate > nowTimestamp}".

HTH

Thanks Ankit Jain,

It worked, but with a side effect. When only your suggestion
(use-when="${thruDate &gt; nowTimestamp}") it shows the button when
thruDate is null.

Try this :
use-when="${thruDate == void @or thruDate&gt; nowTimestamp}"

Pierre,

I have already mentioned that its for second condition and for first
its already working for you so combine both the condition like this.

use-when="${thruDate==null || (thruDate &gt; nowTimestamp)}"

Nicolas, Ankit Jain,

Thanks to both of you.

The suggestion of Nicolas ( use-when="${thruDate == void @or thruDate&gt;
nowTimestamp}" ) still showed the button even when thruDate < nowTimestamp.

The suggestion of Ankit Jain ( use-when="${thruDate==null || (thruDate &gt;
nowTimestamp)}" ) works.

Regards,

Pierre
