Alternating colours on table rows. [message #152573]

Originally posted by: stuart.roe.ovic.co.uk

I have managed to get colours to alternate on table rows via row[0]%2==0
in highlights. But the evaluation appears to occur at an odd time.

I have a List object bound to a table returning a result set listing
item references. The Highlights of the List object has been configured
to vary the background colour according to row[0]%2.

If I place a Data object to display row["item_ref"] in the List's
Detail, the item_ref is shown and field's background colour varies as
expected.

If I modify the object to be bound to a new data source (using item_ref
as a parameter) and display a data item from the new source, the
required data is returned but the alternating colour stops working. I
suspect that the expression is incorrectly using the row[0] value from
the Data object's result set and not the result set from the List
object, where the expression is defined.

Am I doing something wrong? Is BIRT doing something wrong? Does anyone
have a work around, other than writing my SQL to include the item's name
in the first place?

Can you post your design file?

Stuart,
Try adding another list or table in the detail of the outer list
where you have row["entity_name"]. I believe the reason this is not working
is because row[0] is tied to the table or list, and when you changed the
binding I dont think its available anymore. Another option is to use a
global script variable and I have attached an example of this.

Jason

Look at this example, it should run in your designer.
