[2.3.1] Run / RunAnRender - Not the same behaviour

Erwan

Hi,<br />
<br />
First of all, i would like to apologize for my poor english.<br />
<br />
I have noticed a different behaviour between the Run and the RunAnRender tasks. <br />
<br />
My reports use libraries, external js,css and properties.<br />
<br />
When i generate a report with the RunAndRender task in pdf format, i have no error, but a script dataset doesn't work correctly. This dataset is a jdbc dataset which returns a list of authors. In the "onFetch" script function, i denormalized the query in order to store the authors in one string. This variable is used in the footer of the master page. This worked in the 2.2.2, but in the 2.3.1 the string contains only the first author ! Also, when i generate a report with the Run task i get the whole list of authors !<br />
<br />
When i generate a report with the Run task, i get the following error :<br />

I have tried to split my report in order to test where this error comes. This error appears in only some pages of my report. The pages in error use crosstabs. If i remove crosstab it works !<br />
<br />
With this erros, i can't generate any report from rptdocument !<br />
<br />
have you any idea ?
