"Read Constructions Error: variable pi already exists"

Illya

Hello

I have a problem with the Read Constructions. This operator reads a simple file with the attributes that  are constructing  attributes as itself:

<?xml version="1.0" encoding="UTF-8"?>
<constructions version="5.1">
    <attribute name="M_SO2" construction="M_SO2"/>
    <attribute name="M_RAD" construction="M_RAD"/>
    <attribute name="M_UWIND" construction="M_UWIND"/>
    <attribute name="M_VWIND" construction="M_VWIND"/>
    <attribute name="SIN_YEAR" construction="SIN_YEAR"/>
    <attribute name="COS_YEAR" construction="COS_YEAR"/>
</constructions>

The indicator is always yellow and I receive this error::
PM WARNING: Error occurred and will be neglected by Handle Exception: Variable pi already exists.

I don't have it when the Read Construction is disabled.
Thank you in advance for your help and suggestions

Best,
Illya

For what it is worth, I have this problem as well.

Thanks Marco.  I downgraded to 5.2.008 and don't see the problem, so it's definitely a problem with 5.3.

Hi,
thanks for your quick reply!
The  installation of 5.2.000 was not successfull. In this case i can't proof the idea with downgrade. I think it is the best quick fix of the problem in this time (thanks to srt19170)
Marco, how can I know, if the problem is fixed and where can I download the fixed drivers?

Hi,

once this issue has been fixed, I will post an update in this thread. It might take a while before this makes in into a release though. If you cannot wait, you could download the RapidMiner sources and fix the issue for yourself

Any update on this issue?  It's blocking everyone who uses "Read Constructions" from upgrading, so it's a very serious problem.
