So what is the approach or suggestion that you will make to me, I can't let the user click the button if the condition is not going, I used the Show Message to let the user know, but I need sometime else.
If your use case permits it, you can bind the visibility property of the button to the output of your validator widget. If the output is true, the button will be visible, and if it if false, it will now.
Yes I did it before, that's what i don't want to, anyway I created a selective child mashup, but I could avoid reworking if that enable / disable property were there.
The other way to do this, if the click ability is condition based, you can allow the click, but use a Validator Widget to either return a message that the condition is not yet met, or execute the actual service if it has been met.
