Table newbie!
My problem is the table data is not showing up, I see no exceptions
either, simply a blank table with headers. Now to the details ...
I am using SimpleTableModel built from SimpleListTableDataModel and
SimpleTableColumnModel. The SimpleTableColumnModel is built from a bunch
of ExpressionTableColumns and one SimpleTableColumn that builds the
column manually from the row value. There is exactly one row in the list
passed to SimpleListTableDataModel and it doesn't show up. Any gotchas I
need to know?
Thanks,
Harish

Yes, that was strange, perhaps MindBridge can shed some light?

I don't know exactly why things didn't show up without an error, but
the default state manager records page and sorting information into the
session.

Ok, it had to do with the session state manager, although I have no idea
why, yet. I set the session state manager to
NullTableSessionStateManager and I see the data now. I am running
stateless, is that why, I'll have to find out.

Thanks Mindbridge! Yes I see how, now! The Table component has so many
possibilities that some of these easily go unnoticed. Oh BTW did I
mention this component rocks!

Hi Harish,
I think it should be okay to use source/columns in your case. You can do it
in two ways even:
1) 'columns' can accept (besides a string) a column model or a list of
ITableColumn objects. You can pass the SimpleTableColumnModel you have
there, no problem. I believe that should do exactly what you are doing now.
2) You can define the columns also by using a string (as in most current
examples). For the special column you can create a xxxxColumnValue block
that defines how that column should look. In there you can have a Foreach
that goes through the list, etc.
You can access the row object either by using the 'row' binding or by the
ognl expression 'components.table.tableRow' (assuming you use Table. you can
do the same if you use TableRows)
Also, if you want this column not to be associated with an OGNL expression
and thus make it non-sortable, just prepend its name with '!' in the
description string you pass to 'columns'
> On a related topic, is it possible to build a grouped-report with

The easiest way to do that, I guess, is to render Col3 using a Block and a
Foreach, so that items in the list are separated by <br> or sth like that,
and set valign for the table to be 'top' so that the other columns align in
the way you want them. That should achieve it, I think.

The problem is, I have to build one of the columns from a nested list of
data. So each row value has a list attribute that will have to read and
build a string. I didn't seem to find a way to make this work with the
simpler approach.
On a related topic, is it possible to build a grouped-report with
breaks? So in the above case, suppose I wanted to display the nested
list data as a group. Something like ...
Col1 Col2 Col3
Col3
Col3
Col3
Col1 Col2 Col3
Col3
Col3
Col3

Hi Harish,
Just to ask: have you considered using the 'source' and 'columns' bindings
to provide the data and columns instead of the 'tableModel' binding? This
combination tends to be much simpler to use and diagnose if something goes
wrong, and yet covers about 90% of the cases people have.
