B4J Question strange setautocomplete problem

[tufanv]

Hello,

In one of my projects this works fine :

Sub SetAutoComplete(Items As List, Field As TextField)
    Dim jo As JavaObject
    jo.InitializeStatic("org.controlsfx.control.textfield.TextFields")
    jo.RunMethod("bindAutoCompletion", Array(Field, Items))
End Sub

SetAutoComplete(listbittrex,txtcoin)

in another project with the same code i keep getting the error for the line

 jo.InitializeStatic("org.controlsfx.control.textfield.TextFields")

Error occurred on line: 83 (Main)
java.lang.ClassNotFoundException: org.controlsfx$control$textfield$TextFields

Am I missing stg ?

an #additionaljar line maybe?

 

[tufanv]

an #additionaljar line maybe?

in the other project which is working , I have only

    #AdditionalJar: bcprov-jdk15on-159
    #AdditionalJar: sqlite-jdbc-3.7.2

but I dont think they are related. I also tedted with these.

Have you tried adding jControlsFX library, without it I get the same error as you.

Yes ! this fixes the problem. By chance , my other project had that enabled. Thank you !

You really should do more debugging when you have such an error. For me it looks more like you are waisting our time because you are too lazy to search for the problem

Can you help me learn how could i do more debugging on this as I tried some hours trying to figure out the problem without posting here , I also checked my previous projects. I would be very happy if i can learn how could I do it better so next time I can figure the problem myself ?

This line in your stack trace is the clue to the problem:

java.lang.ClassNotFoundException: org.controlsfx$control$textfield$TextFields

Most clues will be found in your stack trace. In this case, the JVM can't find a class (ClassNotFoundException) and we know the package that contains the missing class (org.controlsfx...) so we can infer that the jControlsFX library is missing.
