It should be possible to add conditions in Buttons (like in Rules).
There is no possibility to add a condition when programming a button… or did I miss something?
For instance, I have a 1to1 relation (Sale Opportunity – Feasability Study). When using the button, I want to create a “Feasability Study”. But if it is already created, the button should do nothing (or, better, be unclickable but that’s not the point here).
The only way to do that is through a script. But since everything is already in place for Rules, why is it not available for Buttons?
