ListView in Forms
hi,
first, i'm a very newbie to wicket... I want to add a ListView in a Form.
The ListView has two Texfields and one Checkbox each row. When i submit the
form the values are still the old ones.
here the code:
private class InputForm extends Form {
IModel pluginPropertiesModel;
public InputForm(String id, IPlugin plugin){
super(id);
final IPlugin Iplugin = plugin;
pluginPropertiesModel = new LoadableDetachableModel(){
public Object load()
{
log.debug("load the Model");
Iplugin.loadPluginProperties();
return pluginProperties;
}
};
ListView propertiesList = new ListView("pluginRepeater",
pluginPropertiesModel) {
@Override
public void populateItem(ListItem item)
{
PluginProperties pluginProperties =
(PluginProperties)item.getModelObject();
TextField propertiesName = new TextField("name",new
Model(pluginProperties.getName()));
TextField propertiesValue = new TextField("value",new
Model(pluginProperties.getValue()));
CheckBox propertiesDefault = new
CheckBox("defaultProperty",new Model(pluginProperties.isDefaultProperty()));
item.add(propertiesName);
item.add(propertiesValue);
item.add(propertiesDefault);
}
};
propertiesList.setReuseItems(true);
add(propertiesList);
add(new Button("saveButton"));
}
public void onSubmit()
{
List<PluginProperties> pluginProperties =
(List<PluginProperties>)pluginPropertiesModel.getObject();
for(PluginProperties property:pluginProperties){
info(""+property.getName()+": "+property.getValue()+" ==
"+property.isDefaultProperty());
log.debug(""+property.getName()+": "+property.getValue()+"
== "+property.isDefaultProperty());
}
}
}
thanks in advance

There are a few things going on here... try this and see if it does what you
want it to do. If so reply back and I'll explain what the underlying issue
was:
TextField propertiesName = new TextField("name",new
PropertyModel(pluginProperties, "name"));
TextField propertiesValue = new TextField("value",new
PropertyModel(pluginProperties, "value"));
CheckBox propertiesDefault = new CheckBox("defaultProperty",new
PropertyModel(pluginProperties, "defaultProperty"));

well, it is the way you setup the model by doing new model(value), so
the model acts as the container for the value rather then some glue
between value and some other container such as a class field. see the
models page on the wiki.

Re: ListView in Forms
Posted by Markus Haspl <m....@gmail.com>.
no, there aren't any errors.
but i don't understand why i have to use propertiesName.getModelObject(); in
the onSubmit() method. Because there may be hundrets of propertiesName in
the ListView/Form.
Would it be better to make a Forms in a ListView? But then i need for every
Form a submit-button. that wouldn't be so nice...
thanks

Re: ListView in Forms
Posted by Igor Vaynberg <ig...@gmail.com>.
if there are no errors then you are not using your models properly
TextField propertiesName = new TextField("name",new
Model(pluginProperties.getName()));
to get a value back with a model like that you would have to call
propertiesName.getModelObject()

Why do you use propertiesList.setReuseItems(true)?

Subject: ListView in Forms
hi,
first, i'm a very newbie to wicket... I want to add a ListView in a
Form.
The ListView has two Texfields and one Checkbox each row. When i submit
the form the values are still the old ones.
here the code:
private class InputForm extends Form {
IModel pluginPropertiesModel;
public InputForm(String id, IPlugin plugin){
super(id);
final IPlugin Iplugin = plugin;
pluginPropertiesModel = new LoadableDetachableModel(){
public Object load()
{
log.debug("load the Model");
Iplugin.loadPluginProperties();
return pluginProperties;
}
};
ListView propertiesList = new ListView("pluginRepeater",
pluginPropertiesModel) {
@Override
public void populateItem(ListItem item)
{
PluginProperties pluginProperties =
(PluginProperties)item.getModelObject();
TextField propertiesName = new TextField("name",new
Model(pluginProperties.getName()));
TextField propertiesValue = new
TextField("value",new Model(pluginProperties.getValue()));
CheckBox propertiesDefault = new
CheckBox("defaultProperty",new
Model(pluginProperties.isDefaultProperty()));
item.add(propertiesName);
item.add(propertiesValue);
item.add(propertiesDefault);
}
};
propertiesList.setReuseItems(true);
add(propertiesList);
add(new Button("saveButton"));
}
public void onSubmit()
{
List<PluginProperties> pluginProperties =
(List<PluginProperties>)pluginPropertiesModel.getObject();
for(PluginProperties property:pluginProperties){
info(""+property.getName()+": "+property.getValue()+" ==
"+property.isDefaultProperty());
log.debug(""+property.getName()+":
"+property.getValue()+"
== "+property.isDefaultProperty());
}
}
}
thanks in advance
markus
