How can I assign color attribute for dvt:series dynamically ?

746878Mar 4 2010
I want to assign color for dvt series.

It works good if I set a static color as followed :
<dvt:series index="0" markerType="MT_BAR" color="#000084"/>

However, it doesn't work if I set the color like that:
<dvt:series index="0" markerType="MT_BAR" color="#{mybean.color}"/>

I watched some corresponding documents. They say the color attribute doesn't support el expressions.

How can I solve this problem.


Thanks !

Please, this is not the first question you ask, follow the guidelines!!!

It is imposible to reproduce what you show in the pictures, please copy and paste CODE!!

You should consider something like:

WITH vDesiredData as (SELECT xxx, yyy, zzz FROM YourTable WHERE .....),

     vDefaultData as (SELECT  'A', 1, SYSDATE FROM DUAL)

SELECT * FROM vDesiredData

UNION ALL

SELECT * FROM vDefaultData WHERE NOT EXISTS (SELECT 1 FROM vDesiredData);

In this case if there is data that can be returned, the UNION won't add anything since the NOT EXISTS in the WHERE clause will evaluate to false.

On the other case, when there is no data on vDesiredData, the first SELECT FROM vDesiredData wont return anything but the UNION ALL will incude whatever you configured in vDefaultData

Hello Vemula,

what default value? And maybe it depends of the reason for "no match" (for example: no such emplid but assignemnt_id and assign_sts and start_dt end_dt OK for at least 1 other emplid?... )

Or simply:

WITH your_query AS
( SELECT b.project_id, ... FROM ... WHERE ... )
SELECT NVL( b.project_id, 'your_default_value' ) project_id
  FROM dual
  LEFT OUTER JOIN your_query ON 1 = 1
;

(maybe you want something like "No such combination!" as default value?

Best regards,

Bruno Vroman.
