Caching Problem with BIRT Viewer [message #254458]

BIRT-Viewer is caching report values.

Problem:
I am using dynamic Scripted Data Source for BIRT. If I view the report in
Report-viewer, it shows me the old output unless I hit "Run Report with no
parameters" button at the navigation bar which runs the report again.

Is it a caching problem? If yes, then is there a way to turn caching off?

Speedy reponse will be appreciated.

Thanks,
Swapnil.

Swapnil,

It is caching the report data, but I do not think there is a way to turn
this off. If you select the preview with the Web Viewer icon in the
toolbar it should rerun every time. It should also run every time when
deployed to viewer unless you specify that you want it to use an
existing report document.

Jason,

Thanks for the speedy reply.

I know I can call getStyle() on RowInstance as depicted in the following
code but how should I call getStyle() on IDataItemInstance, there seems to
be no method associated with it. Sorry if I am missing something here.

import
org.eclipse.birt.report.engine.api.script.eventadapter.RowEv entAdapter;
import org.eclipse.birt.report.engine.api.script.IReportContext;
import org.eclipse.birt.report.engine.api.script.ScriptException;
import org.eclipse.birt.report.engine.api.script.instance.IRowInsta nce;
import org.eclipse.birt.report.engine.api.script.IRowData;
import org.eclipse.birt.report.engine.api.script.element.ICell;

public class RowEH extends RowEventAdapter {
public void onCreate(IRowInstance row, IReportContext context) {

IRowData data = row.getRowData();
double minThresh = 0.0;
double expectedThresh = 100.0;
try {
minThresh =
((Double)data.getColumnValue(("row[\"ServiceValueMinimum\"] "))).doubleValue();
expectedThresh =
((Double)data.getColumnValue(("row[\"ServiceValueExpected\ "]"))).doubleValue();
} catch (ScriptException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try
{
for (int i = 0 ; i <= data.getColumnCount(); i++){
if (data.getColumnName(i).equalsIgnoreCase("ServiceExpected") ||
data.getColumnName(i).equalsIgnoreCase("Minimum")
|| data.getColumnName(i).equalsIgnoreCase("CustomerName"))
if (((Double) data.getColumnValue(i)).doubleValue() >= expectedThresh
&& ((Double) data.getColumnValue(i)).doubleValue() > minThresh ) {
row.getStyle( ).setBackgroundColor("#80FF80");
}else if (((Double) data.getColumnValue(i)).doubleValue() >= minThresh
&& ((Double) data.getColumnValue(i)).doubleValue() < expectedThresh ) {
row.getStyle( ).setBackgroundColor("#FEA342");
}else if (((Double) data.getColumnValue(i)).doubleValue() <
expectedThresh && ((Double) data.getColumnValue(i)).doubleValue() <
minThresh ) {
row.getStyle( ).setBackgroundColor("#FF4040");
}
}

} catch (Exception e) {
e.printStackTrace();
}
}

Jason,
Thanks for the reply.
Can you please tell how I should specify about not using existing report
document so that report will be run every time?
I have a static designer file but dynamic scripted datasource.

Swapnil.

Using the __overwrite=true in the url when deployed to the viewer will
do this. There is also a setting in the web.xml that does this
automatically. I do not think it is possible in the preview tab.
