             Summary: [Playground] Fix synchronous validators
                 Key: BEAM-13360
                 URL: https://issues.apache.org/jira/browse/BEAM-13360
             Project: Beam
          Issue Type: Bug
          Components: beam-playground
            Reporter: Ilya Kozyrev


For validators, we start a single goroutine for validateFunc in which we loop through all validators synchronously. 

 
{code:java}
go validateFunc(successChannel, errorChannel, valResChannel)
// Validate returns the function that applies all validators of executor
func (ex *Executor) Validate() func(chan bool, chan error) {
    return func(doneCh chan bool, errCh chan error) {
        for _, validator := range ex.validators {
            err := validator.Validator(validator.Args...)
            if err != nil {
                errCh <- err
                doneCh <- false
                return
            }
        }
        doneCh <- true
    }
}
{code}
 

Instead of that, we should start goroutines for each loop step. And control results for each validator with separate channels.
