Duplicate Markup Ids
I am getting components with duplicate markup ids in my label
components. What can cause this to happen?
I am letting Wicket set the markup ids. Only one user is setup in a
manner that creates the problem, so in general there is not a
duplication problem. As I understand it the markup id number is coming
from the Session's nextSequenceValue method, so I don't see how it could
be duplicated. The components are getting built by multiple instances
of the same class and added into the same array. Here is an example
reduced down to the basic parts:
Several classes build the MyDisplayRow objects and add them to the same
ArrayList...
for (DataRow data : myData)
{
MyDisplayRow row = new MyDisplayRow();
row.setLabelComponent(new Label("headerLabel", data.getTextColumnData());
getMyRowArrayList().add(row);
}
...
ListView<MyDispayRow> repeater = new ListView<MyDisplayRow>("repeater",
myRowArrrayListModel)
{
protected void populateItem(ListItem<MyDisplayRow> item)
{
// Here is where I see the duplicate markup ids
log.debug(item.getModelObject().getLabelComponent().getMarkupId());
item.add(item.getModelObject().getLabelComponent());
}
}

The actual object I am working with is more complex than my code
example. There was a merge row function that was merging rows
together. The merge had a bug where it was merging the row and, in some
scenarios, creating a new row at the same time. This meant that both
the merged row and the extra row had the same component. It was blowing
up because I was adding the same component to different rows in the
repeater. Doh!

I found the problem. It was not a Wicket bug as expected. Thanks for
taking the time to look at this anyway.

The HTML markup is always <span wicket:id="headerLabel"></span>, so I
think the answer is no. I end up with a markup id like "headerLabel8f".

Do you have markup ids pre-defined in your html markup?
