Group reaction error

Post by agustin bruzzese » Tue Jun 07, 2016 5:38 am

this is a simple group reaction between two particles, where im trying to make a group out of them:

<reaction>
<name>AA</name>
<type>group</type>
<educts>
<educt type="particle">A</educt>
<educt type="particle">A</educt>
</educts>
<products>
<product type="group">AA</product>
</products>
<k_forward>100</k_forward>
<k_backward>1</k_backward>
</reaction>

And i get the following error


top: 'step 74000'
action
<ExtendedIdAndType group=false id=0 type=0/>
<ExtendedIdAndType group=false id=1 type=0/>
action2
Exception in thread "main" java.lang.NullPointerException

thanks for your help :)
