ListGridField setHidden issue

[syluster]

Good day , currently I am having an issue regarding the list grid field set hidden issue. As default, the list grid field is shown and there is a checkbox that will enable the set hidden function. When I click the checkbox, the list grid field will be hidden but when I unclick the checkbox again, the list grid field won't show again. The sample code below describe the issue that I am having.



public class home implements EntryPoint {

private ListGrid grid;
private ListGridField name;
private ListGridField discipline;

public home() {

}

@Override
public void onModuleLoad() {

VLayout lay = new VLayout();
lay.setWidth100();

DynamicForm form = new DynamicForm();

CheckboxItem check = new CheckboxItem("check","Check");
check.setShowTitle(false);
check.addChangedHandler(new ChangedHandler(){

@Override
public void onChanged(ChangedEvent event) {
// TODO Auto-generated method stub
if(event.getValue().equals(true)){
setHideGridField();

} else {
setShowGridField();
}

}

});

form.setFields(check);

grid = new ListGrid();
grid.setWidth100();

name = new ListGridField("name","Name");
discipline = new ListGridField("disc", "Discipline");

grid.setFields(name, discipline);

lay.addMembers(form, grid);
lay.setBorder("1px solid black");
lay.draw();

}

public void setHideGridField(){
GWT.log("setGridHidden");
discipline.setHidden(true);
grid.setFields(name, discipline);

}

public void setShowGridField(){
GWT.log("setShowGrid");
discipline.setHidden(false);
grid.setFields(name, discipline);
}

}


Please update me regarding this issue that I am facing now. Thank you

See docs: do not use APIs on ListGridField after they have been provided to setFields(). Use listGrid.showField() / hideField() instead.
