GroovyExecutionScope

CHANNEL_PRODUCT

A ChannelProductContext-instance containing the current product during rule execution.
Attributes can be unwrapped using the following patterns:
def product = GroovyExecutionScope.CHANNEL_PRODUCT.getProduct();
def attribute = product.getAttribute("ATTRIBUTE_ID");

followed by one of the following:

attribute.getValue() // get value of attribute as string
attribute.getValue(String attributeId) // get nested attribute in composite
attribute.getMultiValue() // get iterator over values (String) in multi valued attribute
attribute.getMultiValue(int index) // get the index-th value (String) of multi valued attribute
attribute.getMultiValue(String attributeId) // get iterator over nested attribute in composite in multi valued attribute
attribute.getMultiValue(String attributeId, int index) // get nested attribute in the index-th composite in multi valued attribute

errors

A map containing (String attributeId, String errorMessage) key-value pairs. It can be used in one of the following ways:

GroovyExecutionScope.errors.put("ATTRIBUTE_ID", "Attribute has an error ... [add explanation]");  
return !GroovyExecutionScope.errors.isEmpty();
