<p>Hi there,</p>
<p>I'm pretty new to BIRT and absolutely new to this community. First of all, thank you all for the hard work needed to create such a great platform and for the support thru this community – I really appreciate your efforts.</p>
<p> </p>
<p>So, that said here is my problem. I’m currently using the BIRT designer via eclipse and have created multiple data sources, data sets, a library and a few reports based on the library. Except for some quirks i had while creating the reports (mostly because I’m new to all the BIRT stuff) everything works as expected. The next step I wanted to do, is using the designed reports from a separate, custom Java program via the BIRT report engine API. The Problem arises if I try to get the default values of a report parameter that originally comes from my library. With a minimum example I verified that the general actions that are performed via the java code are working well, and I can retrieve the default value of a parameter that was created directly in the report. I’m using the following method (i tied multiple variants but all lead to the same result):</p>

<p> </p>
<p><span style="color:#000000;"><span style="font-family:consolas;"><span style="font-size:10pt;">This doesn’t work for me if I try it with fresh included parameters from my library. The default value is always returned as null then. If I modify the configuration of the parameter (not actually changing anything) so that it is not a bare reference but saved to the report itself – everything works fine. </span></span></span></p>
<p><span style="color:#000000;"><span style="font-family:consolas;"><span style="font-size:10pt;">Is this the expected behavior? What should I do for not having to “pseudo-modify†all parameters in every report to make it work? Is there some flag to check if the parameter comes from another file (the library) so I can use the original definition <span style="color:#000000;"><span style="font-family:consolas;"><span style="font-size:10pt;">in that case</span></span></span>? Or is it a bug <span style="color:#000000;"><span style="font-family:consolas;"><span style="font-size:10pt;">actually</span></span></span>? (I don’t think so :P)</span></span></span></p>
<p> </p>
<p>I hope someone can help me with that. Thank you!</p>
