may help you . After more investigation on some of the Test Complete forums, it seems this is a known issue. So this really has nothing to do with JavaScript/JScript. This is shown in some forum posts here,

I hope this helps . Not exactly, but there is a way to catch every exception that isn't handled:
code :
>>> import sys
>>> 
>>> def handler(type, value, traceback):
>>>     print "Blocked:", value
>>> sys.excepthook = handler
>>> 
>>> def foo(value):
>>>     print value
>>> 
>>> foo(x)
Blocked: name 'x' is not defined

help you fix your problem After error_log(); in the first try-catch, type throw $e; (on a new line). This will throw the error again, and the outer try-catch will handle it.

Does that help I'm building a custom exception class to manage all exceptions: , You need
code :
try {
   try {
      $this->db = new PDO('mysql:host=localhost;dbname=db;charset=utf8', 'user', 'pass');
   } catch (PDOException $e) {
        throw new MyExceptions($e);
   }
} catch (MyExceptions $f) {
    echo 'caught!';             
}

Any of those help I think the clean way to do this would be using async/await. But before going there, is your question how to not run the outer promise when the inner promise fails?
The example below:
code :
const fun42 = () => {
    return new Promise((resolve, reject) => {
        setTimeout(() =>{
            resolve(42)
            reject('something at fun 42 went wrong')
        }, 500)
    })
}

const fun32 = () => {
    return new Promise((resolve, reject) => {
        setTimeout(() =>{
            //resolve(32)
            reject('something at fun 32 went wrong')
        }, 500)
    })
}

fun32().then(x => {
    console.log(x)
    return fun42()
}).then( y => {
    console.log(y)
}).catch (e => {
    console.log(e)
})
In Java, if a general exception is caught and rethrown, will outer methods still be able to catch specific exceptions?

hop of those help? re-throwing an exception does not change anything about it (it's still the same object originally thrown).
