estoy usando la clase, mostrada aca https://www.b4x.com/android/forum/t...-cross-platform-customlistview.84501/#content
el tema es que se crea sin problemas la lista, pero cuando quiero obtener los datos de la lista, tengo los objetos en blanco.
el problema en especifico lo tengo en el btnMas_Click, en esa fila tengo dos botones, uno para sumar y uno restar, deberia retornar el valor de los dos labels y yo poder sumar y agregar la suma en edittext...
pero el getvalue viene en blanco
