thingworx mashup how to disable a button if a value returned from a service is false

[zyuan1]

Use a Validator widget, create an input for it and check with expression input=false, then bind the Boolean output of the widget to Disabled input of the Button widget

Is there any place  I can read about validator in detail. my scenario is to read a property  from  a thing and validate it using the validator

Hi  @zyuan1 I am able to execute the validator but it only works once when i click one button it disables the other but for some reason it does not refresh back when I hit the second button

[zyuan1]

In your question description you just mentioned one button controlled by service result, what's your second button here for?

You can change the Validator expression to follow your business logic.

@zyuan1 I have two buttons which are start and stop I just want the functionality in such a way where  when one starts the system and other stops it  when I applied 2 validators which read the property and validate the states of these buttons the issue, however, is this process is only happening once even when I checked the auto evaluate property of the  mashup I'm unable to work it out 

[zyuan1]

When the decision process is complex, you could draw a work flow chart including [input value] [expression] [trigger event] [result] to check why it failed.

Another way around, since you need 2 buttons, you could also try the CheckBox widget (Boolean) or RadioButton widget (state definition with 2 String type, OPEN / CLOSE). Carefully design the validator expression and it could be easier than using 2 Buttons.
