Hi,
I have a problem with saving (using Remember operator) and retrieving (using Recall operator) data set into the object store. Here is the XML:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.0">
<context>
<input>
<location/>
</input>
<output>
<location/>
<location/>
</output>
<macros/>
</context>
<operator activated="true" class="process" expanded="true" name="Process">
<process expanded="true" height="521" width="643">
<operator activated="true" class="recall" expanded="true" height="60" name="Recall" width="90" x="500" y="30">
<parameter key="name" value="data_name"/>
<parameter key="io_object" value="ExampleSet"/>
</operator>
<operator activated="true" class="generate_data" expanded="true" height="60" name="Generate Data" width="90" x="112" y="30"/>
<operator activated="true" class="remember" expanded="true" height="60" name="Remember" width="90" x="246" y="30">
<parameter key="name" value="data_name"/>
<parameter key="io_object" value="ExampleSet"/>
</operator>
<connect from_op="Recall" from_port="result" to_port="result 1"/>
<connect from_op="Generate Data" from_port="output" to_op="Remember" to_port="store"/>
<portSpacing port="source_input 1" spacing="0"/>
<portSpacing port="sink_result 1" spacing="0"/>
<portSpacing port="sink_result 2" spacing="0"/>
</process>
</operator>
</process>
When running this simple code, I always get com.rapidminer.operator.UserError exception, process fails with the reason "No object with data_name was found during retrieval from the object store", where the offending is the Recall operator. Is this a bug or am I doing something wrong? Do I have to configure object store somehow? I am using RM 5.0.3 on WinXP.
Thanks
Dan
