Re: Problems with CheckGroup
so the next step is to step into convertinput() and see why its
returning a string instead of a collection.

Re: Problems with CheckGroup
Debugging the code just tells me the same as the exception does:
CheckGroup.updateModel:
public void updateModel()
{
Collection collection = getModelObject();
if (collection == null)
{
collection = getConvertedInput();
setDefaultModelObject(collection);
}
else
{
modelChanging();
collection.clear();
collection.addAll(getConvertedInput()); <-
modelChanged();
}
}
getConvertedInput() returns a String instead of a collection instance.
This just has to be wrong, because it returns T, the parameter of
FormComponent, and CheckGroup extends FormComponent>.
Removing the setType-Call doesn't help.

Problems with CheckGroup
Hi all
I'm trying to use CheckGroup, but encounter some problems. First, my code:
class NameValueListView> extends
ListView {
void displayItem(ListItem listItem, ParameterValueProvider
parameter) {
...
List enumItems = new ArrayList(parameter.getEnumCodes());
addMultiSelectPanelListItem(listItem, enumItems, labelModel, new
PropertyModel>(parameter,
"valueList"), parameter);
}
void addMultiSelectPanelListItem(ListItem listItem,
List enumItems, IModel labelModel,
IModel> model,
final ParameterValueProvider parameter) {
CheckGroup comp = new CheckGroup("value");
comp.setType(parameter.getType());
comp.setRequired(!parameter.isOptional());
comp.setLabel(labelModel);
ListView enumListView = new ListView("values", enumItems) {
@Override
protected void populateItem(ListItem item) {
item.add(new Check("check", item.getModel()));
item.add(new Label("value",
item.getDefaultModelObjectAsString()));
}
};
enumListView.setReuseItems(true);
comp.add(enumListView);
// Add panel
MultiCheckBoxPanel panelMCB = new
MultiCheckBoxPanel(COMPONENT_ID, comp);
listItem.add(panelMCB);
}
}
ParameterValueProvider has the mehtods {get,set}Value[List].
The html looks like this:
So far, so good. Values are getting displayed and the correct check
boxes are selected. However, when submitting the form, I get an exception:
---
