Hi,
The below explanation is also related to another message that appeared
on the list a bit earlier.
It is important to remember the below principle when working with
contrib:Table (and I am making a point to emphasize it in the docs).
There are two distinct aspects of a table column:
- The first one is the value used for sorting. This is the OGNL
expression given in the 'columns' string.
- The second one is the visual representation of the column. By default
that is simply the string representation of the value used for sorting,
as the two often coincide. Nevertheless, it is possible to define a more
elaborate representation by declaring a Block with a name
<column_id>ColumnValue.
To apply those principles, here is how I would approach what you want to do:
In the .page/.jwc:
<binding name="columns">
accountNumber, firstName, lastPurchase:amount, visitCnt, lastDate
</binding>
In the .html:
<span jwcid="[EMAIL PROTECTED]">
$<span jwcid="@Insert"
value="formatCurrency(components.membersTableView.tableRow.amount)"/>
</span>
<span jwcid="[EMAIL PROTECTED]">
<span jwcid="@Insert"
value="formatNumber(components.membersTableView.tableRow.visitCnt)"/>
</span>
<span jwcid="[EMAIL PROTECTED]">
<span jwcid="@Insert"
value="formatDate(components.membersTableView.tableRow.lastDate)"/>
</span>
In .properties:
accountNumber=Account Number
firstName=First Name
lastPurchase=Last Avg Purchase
visitCnt=Number Visits
lastDate=Last Date
In that way the columns will be sorted properly, there is more freedom
to make them look like it is needed, and column titles can contain
random symbols and are internationalizable.
Please note that the code has not been tested and may contain bugs here
and there -- best to just extract the principles from it. There are
other less verbose ways to do the above (e.g. with a 'row' property),
but that is an optimization.

I'm trying to get the contrib:table to format my data (date, currency,
numbers, etc) then be able to sort it.
I'm using Tapestry 4 beta 2.
I'm able to get it to format properly, probably not the "correct" way - I
use a method from my bean that is being rendered in my table to format the
value and return it as a String. The problem I have now is that when I
sort, I'm sorting strings, when it really needs to be sorting number, dates,
etc.
Here's what I have in my .page file:
<component id="membersTableView" type="contrib:TableView">
<binding name="source" value="ognl:members" />
<binding name="columns">
Account Number:accountNumber, First Name:firstName, Last
Avg Purchase:"$" + formatCurrency(amount), Number
Visits:formatNumber(visitCnt),
Last Date:formatDate(lastDate)
</binding>
</component>
<component id="membersTableColumns" type="contrib:TableColumns" />
<component id="membersTablePages" type="contrib:TablePages" />
<component id="membersTableFormRows" type="contrib:TableRows"></component>
<component id="membersTableValues" type="contrib:TableValues" />
The methods (formatCurrency, formatNumber, formatDate) are in my "Member"
bean that the table is rendering. So this works for the format, but when I
sort by clicking on the column headers they are now strings, which doesn't
work as needed.
Any advice is greatly appreciated.
Thanks,
Joe
