B4J Question TabPane problem

[micro]

I have a TabPAne named Tabmain with four TabPage ("tab1", "tab2", "tab3", "tab4") designed with javafx scene builder.
If in my code insert this:

Log(Tabmain.Tabs.Get(0)) 'first TabPage = "tab1"

The program crash with this log:

Error occurred on line: 122 (main).

This works for me with B4j V1.50:

Dim T As TabPage = TabMain.Tabs.Get(0)
    Log(T.Text)

What version of B4j are you using?

You can set the selected TabPage using:

TabMain.SelectedIndex = 1

for page 2.

B4J version: 1.50
and so does not work
rechecking.......

If you can please upload your project (File - Export as zip).

Hola por favor ayuda con el uso de TabPane cada uno con su propio modulo, como llamo al modulo y este a la vez al layaut correspondiente. Gracias
Tengo 5 Code Module y con cada uno de ellos tengo un layout lo que quisiera es ocupar el TabPane.

Hola!

recuerda que tienes el foro en español:
https://b4x.com/android/forum/forums/spanish-forum.12/

Donde tambien se pueden resolver problemas de B4J.

para tu duda:

Creas una instancia de TabPage, la inicializas
Creas una instancia de PInterno que va a fungir como el panel interno del TabPage
El Panel lo pones como content de la TabPage
y con eso ya puedes hacer un loadLayout.
Por ultimo, mete el TabPage al TabPane

        Dim menuPage As TabPage
        menuPage.Initialize
        Dim pInterno As Pane
        pInterno.Initialize("")
    
        menuPage.Content = pInterno

        menuPage.Text = "Información"
        menuPage.Content.LoadLayout("layoutinformacion")

        principalTab.Tabs.Add(menuPage)
