Double Query execution in RunTask and RenderTask

Rainer

Hi all,<br />
<br />
I integrated ReportEngine in Web Application. After migrating to 2.5.2 I am using IProgressMonitor zu log status of report execution. Report execution is done by RunTask writing rptdocument and then RenderTask to render the output in the desired format. I checked the records that IProgressMonitor writes into the logfile and it seems that both RunTask and RenderTask execute all defined report Queries.<br />
<br />
This is the output I got from logfile. <br />
<br />
DEBUG 11:03:40,552 btpool0-7 - <span style='color: #FF0000'>Starting Run Task</span><br />

<br />
I thought rptdocument would contain data from query execution and further operations on database<br />
are not nessessary.<br />
Its only very little time that is spent in RenderTask because data in this case come<br />
from Query Cache but in my eyes redundant. Does RenderTask execute report Queries? and if so,<br />
is there way to avoid it?<br />
<br />
