v 1.2 comes with
.palm-dialog-box .label.left.mv-picker-label {
display: none;
}
in global-widget-mvpicker.css
to overcome this changed in your css:
.palm-dialog-box .label.left.mv-picker-label {
display: block;
}
SDK version 1.2 issue
The problem happens when you try to call those dialogs from within a dialog created via
this.controller.showDialog(...) with preventCancel: true.
changing it to preventCancel: false Fixed the problem.
