Thanks. So what should be in method DragSource#onBeforeDrop()? I should set there transfer data: transfer.setData(drag); ? I have Wicket 1.5.4 and wicket-dnd 0.5.0. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/help-with-drag-and-drop-wicket-dnd-tp4422338p4423719.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: help with drag and drop (wicket-dnd)
Hi,
your s have to output their markup id too.
transfer.getData() allways NULL. What should be in transfer?
The transfer objects hold whatever the dragsource puts into it. If you haven't
overriden DragSource#onBeforeDrop() this is just the model object of the
dragged element.
BTW which version are you using?

bbb.setOutputMarkupId(true);
ccc.setOutputMarkupId(true);

targeted (drop)?

Re: Performance optimization
Here is how I managed to do ajax refresh:
final Component
newDummyAjaxUpdateComponentFromMarkup =
TakpPanelWithDynamicMarkup.newDummyAjaxUpdateComponentFromMarkup(freshMarkup,
markupId, false);
if (newDummyAjaxUpdateComponentFromMarkup != null) {
target.addComponent(newDummyAjaxUpdateComponentFromMarkup);
}
public static Component newDummyAjaxUpdateComponentFromMarkup(String
freshMarkup, String markupId, boolean required) {
XmlPullParser xmlPullParser = new XmlPullParser();
try {
xmlPullParser.parse(freshMarkup);
} catch (Exception e) {
throw new RuntimeException(e);
}
XmlTag xmlTag = findStartTag(xmlPullParser, markupId);
if (xmlTag != null) {
final StringBuilder stringBuilder = new StringBuilder();
final int startEndPosition;
{
final String tagAsString = xmlTag.toString();
stringBuilder.append(tagAsString);
startEndPosition = xmlTag.getPos() + tagAsString.length();
}
{
try {
xmlTag = (XmlTag) xmlPullParser.nextTag();
} catch (Exception e) {
if (required) {
throw new RuntimeException(e);
}
// else
Utils.errorLog(TakpPanelWithDynamicMarkup.class, e);
}
stringBuilder.append(xmlPullParser.getInput(startEndPosition,
xmlTag.getPos())); // Value inside
stringBuilder.append(xmlTag.toString());
}
return new TakpPanelWithDynamicMarkup(markupId) {
private transient IResourceStream markupResourceStream;
@Override
public IResourceStream getMarkupResourceStream(MarkupContainer
container, Class containerClass) {
if (markupResourceStream == null) {
final StringBufferResourceStream stream = new
StringBufferResourceStream();
stream.append("");
stream.append(stringBuilder);
stream.append("");
markupResourceStream = new MarkupResourceStream(stream);
}
return markupResourceStream;
}
};
} else if (required) {
throw new IllegalStateException("Component with markup id " +
markupId + " not found from markup stream " + freshMarkup);
}
return null;
}
It could be streamlined ofcourse.. with duality it could be native
part of wicket ;)

Hi Dan,
only a shot in the dark - but is your markup valid? validate with w3c.
PS: Is it required to add the ending slash?

Re: help with drag and drop (wicket-dnd)
Hi,
with .drag("span") you tell the drag source that drags should start on
span tags.

Do you have a span tag in your markup?
