They way I got mine to work (I think my thread was the one you were
referring too) was initialize the table in pageAttached() and used @Persist
for the source/column getters.
So something like:
@Persist
public abstract ITableColumnModel getColumns()
public abstract void setColumns(ITableColumnModel foo)
@Persist
public abstract IBasicTableModel getTableModel()
public abstract void setTableModel(IBasicTableModel bar)
Then in pageAttached (that's what I did) {
setColumns(new Foo());
setTableModel(new Bar());
}
You could also initialize in some method like "activatePage" or whatever and
have a Link listener called the method to initialize the data.
I dunno if this is the proper way of doing things (I fairly new to
Tapestry), but it works for me with caching/no-caching modes.

Yes I did check those examples out. And indeed they were useful. And I
still have problems.
This morning I realized I had forgotten to put my source's data property
persistent in the session.
And bumped into another problem. Now I don't even see my table on the
first load, but have this exception:
Either the tableModel parameter or both source and columns parameters must
be specified by component Results/resultsTable.tableView
This issue has been discussed on this mailing-list, but I couldn't find a
solution to my problem so far :(
My source is in an object called dOsList of type java.util.List.
I lazy-initialize this object in its getter method.
Thus my pageBeginRender() method is empty (the dOsList being null on first
load is handled by the getter).
I have in my page specification <property name="dOsList"
persist="session"/>
So that in my HTML template I have: source="ognl:dOsList" for my table
component.
I know (with the debugger) that my getDOsList() on my page is *not*
called. I just can't figure out why.
I can also see from the Tapestry exception page that my dOsList property
is not stored in the session.
I call it a bad day. Any thoughts?

Subject: contrib:Table : advices requested
Hi folks!
I'm using the contrib:Table for the first time. I'm using the source and
columns parameters (and therefore not the tableModel parameter).
My source is a List of DOs, where each DO contains some fields (Date,
double, int, etc.) with getters.
--
Q1: My table does show up as expected, with the page navigation system.
But when I'm trying to change the page, I have this error:
Failure invoking listener method 'public void
org.apache.tapestry.contrib.table.components.TablePages.changePage(org.apache.tapestry.IRequestCycle)'
on [EMAIL PROTECTED]/resultsTable.tablePages]: 1
and that's an ArrayIndexOutOfBoundsException: 1.
I have a similar error when I'm trying to sort a column. It really does
sound easy to solve, but I'm stuck.
--
Q2: I have a column which displays a price. So quite naturally the field
in my DO is a double. I want a string in front of my double, so I
figured I needed to have a column with a custom ColumnEvaluator.
Something like this:
public ITableColumn getPriceColumn() {
SimpleTableColumn priceColumn = new SimpleTableColumn("priceId",
"Price", new PriceColumnEvaluator(), true);
return priceColumn;
}
private static class PriceColumnEvaluator implements
ITableColumnEvaluator { public Object getColumnValue(ITableColumn
objColumn, Object objRow) {
DO row = (DO) objRow;
String output = row.getCurrency() + " " + row.getPrice();
return output;
}
}
However, I suspect my price sorting does not work anymore because now
the data type for my price column is a String (since my Evaluator
returns a String). I was not comfortable with doing this formatting
thing (adding the currency sign) in my evaluator in the first place,
since it was not "pure data" stuff. Would you have implemented it
elsewhere?
Related to this, I will need another column in which I'll have to
display a little picture (which will be a link) and a few other things.
Is using a customColumnEvaluator the preferred way to do it?
Again, any hints appreciated.
/Martin
