Marcin Palka updated WICKET-2043:
---------------------------------
Description:
I use a DropDownChoice with a model of SelectOption objects and a
ChoiceRenderer (see code below).
This is how I create a DropDownChoice instance:
DropDownChoice separatorDropDown = new DropDownChoice(
"separatorDropDown",
new PropertyModel(this, "separator"), //separator is a field in
my class
new Model(new ArrayList(Arrays.asList(separators))),
//separators is an array of SelectOption objects
choiceRenderer);
This is how the SelectOption looks like:
class SelectOption implements Serializable {
private String key;
private String value;
public SelectOption(String key, String value) {
this.key = key;
this.value = value;
}
public String getKey() {
return key;
}
public void setKey(String key) {
this.key = key;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
@Override
public String toString() {
return getKey();
}
}
And this is how choiceRenderer looks like
ChoiceRenderer choiceRenderer = new ChoiceRenderer("key", "value");
These are the values that my model consist of:
private SelectOption[] separators = new SelectOption[]{
new SelectOption("comma", ","),
new SelectOption("semicolon ", ";"),
new SelectOption("dot", "."),
new SelectOption("tab", "\t"), //causes null
new SelectOption("tabandtex", "\ttext"), //causes null
new SelectOption("space", " ")};
Whenever any item containing a \t (tab character) in its value field is
selected, the separator field that PropertyModel points to becomes null.
Otherwise correct SelectOption instance is being set into separator.
I noticed that tab characters are missing from the output markup generated by
wicket.
<select wicket:id="separatorDropDown" ...>
<option selected="selected" value=",">comma</option>
<option value=";">semicolon </option>
<option value=".">dot</option>
<option value=" ">tab</option>
<option value=" text">tabandtex</option>
<option value=" ">space</option>
</select>
