Almost.... still needs some tweaking:
org.apache.wicket.WicketRuntimeException: Unable to find the markup
for the component. That may be due to transparent containers or
components implementing IComponentResolver: [MarkupContainer
[Component id = -]]

org.apache.wicket.MarkupFragmentFinder.find(MarkupFragmentFinder.java:125)
at org.apache.wicket.Component.locateMarkupStream(Component.java:3813)

>> Hi!
>>
>> Can a wicket component be rendered to string in the following use case:
>>
>> 1. I have a table (multiple columns and rows). Each row corresponds to
>> a person. The columns could represent for rexample a calendar for the
>> person. Monda, tuesday, etc.
>>
>> 2. For each row, I have summary information. I have a SummaryPanel
>> that can show this information at the footer of the table.
>>
>> 3. In addition to the footer, I would like to show the SummaryPanel
>> contents as a tooltip.
>>
>> 4. I would like to attach the tooltip onto an icon in each column for
>> each row (tooltip content different for different rows, same for
>> different columns on the same row).
>>
>> 5. Ideally I would do like this:
>> populateitem(ListItem item) {
>> item.add(new Tooltip("tooltip", new AbstractReadOnlyModel<String>()
>> { public String getObject() { RenderUtils.renderToString(new
>> SummaryPanel("dummy-id")) } });
>> }
>>
>> I.e., I need to render a panel to a string during an ongoing render.
>>
>> I have found an example for rendering a wicket PAGE

>> Furthermore, I have found an example about rendering using a new request
