Hi i am using vaadin 7.4.3 with dragdroplayouts addon 1.1.3 version it is working fine. but when i changed vaadin version to 7.6.1 and dragdroplayout 1.2 it is not working.

java.lang.ClassCastException: fi.jasoft.dragdroplayouts.client.ui.formlayout.DDFormLayoutState cannot be cast to com.vaadin.shared.ui.orderedlayout.FormLayoutState at com.vaadin.ui.FormLayout.getState(FormLayout.java:78) at com.vaadin.ui.FormLayout.getState(FormLayout.java:34) at fi.jasoft.dragdroplayouts.DDFormLayout.getState(DDFormLayout.java:244) at fi.jasoft.dragdroplayouts.DDFormLayout.getState(DDFormLayout.java:49) at com.vaadin.ui.AbstractOrderedLayout.setSpacing(AbstractOrderedLayout.java:291) at com.vaadin.ui.FormLayout.(FormLayout.java:38) at fi.jasoft.dragdroplayouts.DDFormLayout.(DDFormLayout.java:49)

please give solution

Can you verify that you are actually using dragdroplayouts 1.2 and don't have duplicate versions on your classpath? Also did you re-compile the widgetset after you updated?

Since 1.2 DDFormLayoutState extends FormLayoutState so you should not be able to get that excecption if you are using the right version.

Cannot reproduce this and closing this as this is most likely an issue with the setup (multiple ddlayouts versions on the classpath).
