Hi!
Thanks for pointing that out.. must have been drunk when I coded that >8-)
Here is an improved version:
/**
* @see
org.apache.wicket.markup.html.form.AbstractChoice#appendOptionHtml(org.apache.wicket.util.string.AppendingStringBuffer,
java.lang.Object, int, java.lang.String)
*/
@Override
protected void appendOptionHtml(AppendingStringBuffer buffer, T choice,
int index, String selected) {
AppendingStringBuffer tmp = new AppendingStringBuffer(50);
super.appendOptionHtml(tmp, choice, index, selected);
if (getChoiceRenderer() instanceof IStyledChoiceRenderer) {
IStyledChoiceRenderer<T> styledChoiceRenderer =
(IStyledChoiceRenderer<T>) getChoiceRenderer();
String currentOptGroupLabel =
styledChoiceRenderer.getOptGroupLabel(choice);
if (!Utils.equalsOrNull(currentOptGroupLabel,
previouslyAppendedOptGroupLabel)) {
// OptGroup changed
if (previouslyAppendedOptGroupLabel != null) {
endOptGroup(buffer);
}
if (currentOptGroupLabel != null) {
// OptGroup started
int start = tmp.indexOf("<option");
StringBuilder label = new
StringBuilder(currentOptGroupLabel.length() + 19);
label.append("<optgroup
label=\"").append(currentOptGroupLabel).append("\">");
tmp.insert(start, label);
}
}
if ((currentOptGroupLabel != null) && (index == (choices-1))) {
// Last option group must end too
endOptGroup(tmp);
}
{
String cssClass = styledChoiceRenderer.getOptionCssClassName(choice);
if (cssClass != null) {
int start = tmp.indexOf("<option");
tmp.insert(start + 7, new StringBuilder("
class=\"").append(cssClass).append("\""));
}
}
previouslyAppendedOptGroupLabel = currentOptGroupLabel;
}
buffer.append(tmp);
}
/**
* @param tmp
*/
private void endOptGroup(AppendingStringBuffer tmp) {
// OptGroup ended
int start = tmp.lastIndexOf("</option>");
tmp.insert(start + 9, "</optgroup>");
}
It produces:
<select wicketpath="ddc" name="ddc">
<option value="" selected="selected">Valitse yksi</option>
<optgroup label="group0">
<option value="0">text0</option>
<option value="1">text1</option>
<option value="2">text2</option>
</optgroup>
<optgroup label="group1">
<option value="3">text0</option>
<option value="4">text1</option>
<option value="5">text2</option>
</optgroup>
<optgroup label="group2">
<option value="6">text0</option>
<option value="7">text1</option>
<option value="8">text2</option>
</optgroup>
</select>
