This question is both related to Seam and Richfaces. I'm not sure which fourm should I post this question on so I just posted on both.
I'm using Seam 3 and Richifaces 4
I have on page named 'report.jsf'. It has a parameter 'id'.
The url is like: report.jsf?id=123
On the page, there is a view action
<s:viewAction action="reportManager.loadReport" />
This method will fetch report from DB according to the id.
Also on this page, I used
<a4j:mediaOutput element="img" cacheable="false" session="false"
to display a JFreeChart. The paint method will dynamically create a chart according to the report info got from DB.
In loadReport method it will get data from DB which will be used by paint method.
Here is the problem:
The report page displays the report info correctly but the chart does not. The chart is always empty.
I guess reportManager.paint is called before loadReport fetches the data to generate the chart.
How to lodaReport firstly and then paint the chart?
Can anyone show me an example which uses a view action to load data and dynamically generate a JFreechart and display in medialOutPut?
Retrieving data ...
