[Wicket-user] Adding extra row to table in ListView
I'm using a custom ListView to generate a table. The content of the
table consists of four columns of data. I have that working just
fine. But I'd like to add an additional table row on occation to
group rows of data in the table. Thus, there would be a groupRow
that specifies a date, then many availRows of data for that date, then
another groupRow, more availRows, and so forth.
Here is some example HTML. I know that this HTML and code will not
work the way it is now -- it is just meant to illustrate. The first
TR should only be displayed when the date changes. Otherwise, only
the second TR should display in each populateItem.
table
tr wicket:id=groupRow
td colspan=4 wicket:id=date/td
/tr
tr wicket:id=availRow
td wicket:id=lastName/td
td wicket:id=firstName/td
td wicket:id=startTime/td
td wicket:id=endTime/td
/tr
/table
Here is the custom ListView's populateItem:
protected void populateItem(final ListItem item) {
SimpleDateFormat dateDateFormat = new SimpleDateFormat(M/d/);
SimpleDateFormat timeDateFormat = new SimpleDateFormat(h:mma);
ReportRow rr = (ReportRow) item.getModelObject();
Date update = getStartDate(rr.getStartTime());
if (current == null || current.getTime() update.getTime()) {
current = update;
item.add(new
Label(date,dateDateFormat.format(rr.getStartTime(;
}
else {
item.add(new Label(lastName,rr.getLastName()));
item.add(new Label(firstName,rr.getFirstName()));
item.add(new
Label(startTime,timeDateFormat.format(rr.getStartTime(;
item.add(new
Label(endTime,timeDateFormat.format(rr.getEndTime(;
}
}

Re: [Wicket-user] Adding extra row to table in ListView
what you need is a lsitview in a listview
the first outputs the date row, and then a listview that outputs rows for
that date.
makes sense?

Re: [Wicket-user] Adding extra row to table in ListView
Igor,
Yes, that makes sense. However, I get the data for the list using a
single HQL query with joins and such. If I changed to a ListView
within a ListView, then wouldn't I also need to change to do many HQL
queries to build a bunch of small lists within a big list? I don't
know what the performance implications would be of making this change.
Also, last night I was working on switching it to a DataView instead
of a ListView. Could a single DataProvider supply the data for both
the outer and inner views?
Thanks!

you can still have only one list. then have an imodel implementation that
filters that list on the fly.

Re: [Wicket-user] Adding extra row to table in ListView
Igor,
Upon further thought, how can a ListView inside a ListView solve this?
Wouldn't the hierarchy cause the html to be messed up? I can't have
TRs within TRs. The inner listview isn't putting child data inside of
the TR, it needs to make TRs that are siblings of the outer listview.
The output should be like this:
table
tr wicket:id=groupView --- Outer listview
td wicket:id=groupTitle/td
/tr
tr wicket:id=dataView --- Inner listview
td wicket:id=data/td
/tr
/table
Not like this:
table
tr wicket:id=groupView --- Outer listview
td wicket:id=groupTitle/td
tr wicket:id=dataView --- Inner listview
td wicket:id=data/td
/tr
/tr
/table
What am I not getting?
Thanks,
Tauren

Re: [Wicket-user] Adding extra row to table in ListView
you dont have to attach the listview to the trs though
in 1.2.6
you can attach it to span and do dataview.newitem(..) { return super.newitem
(..).setrenderbodyonly(true);
table
span wicket:id=groupView --- Outer listview
tr
td wicket:id=groupTitle/td
/tr
span wicket:id=dataView --- Inner listview
tr
td wicket:id=data/td
/tr
/span
/span
/table
in 1.3 we have a placeholder that makes this easier
table
wicket:container wicket:id=groupView --- Outer listview
tr
td wicket:id=groupTitle/td
/tr
wicket:container wicket:id=dataView --- Inner
listview
tr
td wicket:id=data/td
/tr
/wicket:container
/wicket:container
/table
advantage of wicket:container is that it will validate markup even at design
time, and it is stripped when strip-wicket-tags option is enabled.
rarely you do hit these cases where doing this in a jsp is easier because
the jsp renders top-down, but in my experience they are few and far in
between. and more importantly we have solutions to make them work.

Re: [Wicket-user] Adding extra row to table in ListView
Sweet! I do have it working with an extra tag (where you use the
span), but I didn't like that it rendered invalid html. Didn't know
about setrenderbodyonly. Thanks for the tip! When I move to 1.3,
I'll use the container approach.
Thanks Igor!
