B4J Question java.lang.reflect.InvocationTargetException if to make CallSub2

[peacemaker]

Hi, All

A class has internal HTTP requests and with callbacks:

Sub handleRequestUploadPath(Job As HttpJob, res As String)
    Dim parser As JSONParser
    parser.Initialize(res)
    Dim root As Map = parser.NextObject
    root.Put("Tag", Job.Tag)
    If SubExists(Me, "meyadisk_RequestUploadPath") Then
        CallSub2(Me, "meyadisk_RequestUploadPath", root)    'ME - it's the class itself
    End If
End Sub

And in DEBUG mode sometimes i have error in this CallSub2 line:

Error occurred on line: 245 (yadisk)

Mostly all works OK.
But sometimes is this error, what does it mean ? The class itself always exists...

I don't understand that code. As you are writing the class you should know whether the sub exists or not and you can call it directly.

If you intend to catch it with Wait For then you should use CallSubDelayed.

CallSubDelayed

Yes, helped, thanks !
