Alternate Filtering Configuration File Example
The out-of-the-box file for configuring the alternate Option filtering behavior is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<FilterStrategy handler="com.ptc.windchill.option.filter.DefaultFilterStrategyHandler">
<FilterNode type="wt.option.ExpressionAssignable">
<ExpressionPolicy advanced="true" mode="STANDARD,UNDEFINED"/>
<FilterNode type="wt.option.ChoiceMappable">
<ExpressionPolicy advanced="false" mode="STANDARD,UNDEFINED"/>
Note that the only difference with the standard filtering mode is that a filter node will be filtered out if the expression contains an undefined choice or it evaluates to false.
