Manula Chathurika Thantriwatte commented on STRATOS-1108:
---------------------------------------------------------
Hi,
This issue was fixed in Stratos 4.0.0. Here I have attached the CEP extension
patch. We need to apply the patch changes to Stratos 4.1.0 as well. This fix
depends on the siddhi core fix which was done to the
siddhi-core_2.0.0.wso2v4.jar. So we need to wait for the CEP release because
the fix done to the siddhi-core_2.0.0.wso2v4.jar is currently not available in
nexus.
Thanks !
