Use a Loop Macro in a Function Expression

mugicagonzalez_

Hello all

It's possible to "Generate Attribute" with a function expression that includes an attribute (for example var1 = var + 1).
If I now want to replace these variables with macros, it doesn't work (because it is seen as text, and not as a variable). (for example %{loop-var} = %{loop-var} + 1

Example in here (all imported vars starting with Wh are numerical).

<div><?xml version="1.0" encoding="UTF-8"?><process version="8.1.003"></div><div>&nbsp; <context></div><div>&nbsp; &nbsp; <input/></div><div>&nbsp; &nbsp; <output/></div><div>&nbsp; &nbsp; <macros/></div><div>&nbsp; </context></div><div>&nbsp; <operator activated="true" class="process" compatibility="8.1.003" expanded="true" name="Process"></div><div>&nbsp; &nbsp; <process expanded="true"></div><div>&nbsp; &nbsp; &nbsp; <operator activated="true" class="retrieve" compatibility="8.1.003" expanded="true" height="68" name="Retrieve values" width="90" x="45" y="34"></div><div>&nbsp; &nbsp; &nbsp; &nbsp; <parameter key="repository_entry" value="//Local Repository/data/delete_me/values"/></div><div>&nbsp; &nbsp; &nbsp; </operator></div><div>&nbsp; &nbsp; &nbsp; <operator activated="true" class="concurrency:loop_attributes" compatibility="8.1.003" expanded="true" height="82" name="Loop Attributes" width="90" x="179" y="34"></div><div>&nbsp; &nbsp; &nbsp; &nbsp; <parameter key="attribute_filter_type" value="regular_expression"/></div><div>&nbsp; &nbsp; &nbsp; &nbsp; <parameter key="regular_expression" value="Wh_.+"/></div><div>&nbsp; &nbsp; &nbsp; &nbsp; <parameter key="attribute_name_macro" value="loop_Wh"/></div><div>&nbsp; &nbsp; &nbsp; &nbsp; <parameter key="enable_parallel_execution" value="false"/></div><div>&nbsp; &nbsp; &nbsp; &nbsp; <process expanded="true"></div><div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <operator activated="true" class="generate_attributes" compatibility="8.1.003" expanded="true" height="82" name="Generate Attributes (11)" width="90" x="112" y="34"></div><div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <list key="function_descriptions"></div><div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <parameter key="k%{loop_Wh}" value="%{loop_Wh} / 1000"/></div><div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </list></div><div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </operator></div><div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <connect from_port="input 1" to_op="Generate Attributes (11)" to_port="example set input"/></div><div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <connect from_op="Generate Attributes (11)" from_port="example set output" to_port="output 1"/></div><div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <portSpacing port="source_input 1" spacing="0"/></div><div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <portSpacing port="source_input 2" spacing="0"/></div><div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <portSpacing port="sink_output 1" spacing="0"/></div><div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <portSpacing port="sink_output 2" spacing="0"/></div><div>&nbsp; &nbsp; &nbsp; &nbsp; </process></div><div>&nbsp; &nbsp; &nbsp; </operator></div><div>&nbsp; &nbsp; &nbsp; <connect from_op="Retrieve values" from_port="output" to_op="Loop Attributes" to_port="input 1"/></div><div>&nbsp; &nbsp; &nbsp; <connect from_op="Loop Attributes" from_port="output 1" to_port="result 1"/></div><div>&nbsp; &nbsp; &nbsp; <portSpacing port="source_input 1" spacing="0"/></div><div>&nbsp; &nbsp; &nbsp; <portSpacing port="sink_result 1" spacing="0"/></div><div>&nbsp; &nbsp; &nbsp; <portSpacing port="sink_result 2" spacing="0"/></div><div>&nbsp; &nbsp; </process></div><div>&nbsp; </operator></div><div></process></div>

How do I bypass this?

Thanks

Solved by using the "eval" function: eval(%{loop-var}) = eval(%{loop-var}) + 1
