[ https://issues.jboss.org/browse/DROOLS-3152?page=com.atlassian.jira.plugi... ] Michael Anstis commented on DROOLS-3152: ---------------------------------------- Sorry [~tari_manga] but your _fix_ for DROOLS-3116 has caused this regression. The problem is that we need [this|https://github.com/kiegroup/kie-wb-common/commit/ba5aefec948af9f1167...] to ensure there is an expression on a {{ContextEntry}} (and other cases) when the file is saved. However we want to be able to differentiate [here|https://github.com/kiegroup/kie-wb-common/commit/ba5aefec948af9f1167...] between the mock {{LiteralExpression}} added in the foregoing (i.e. really there was a {{null}} expression) and a {{LiteralExpression}} that has an empty value. Trisotech manage this in the follow way: 1) {{null}} Expression (i.e. empty {{ContextEntry}}) {{<dmn11:literalExpression/>}} (No *ID*) 2) Empty (no text, {{null text}}) {{LiteralExpression}} {{<dmn11:literalExpression id="_6e353f23-efd5-4ee7-98e6-3593c7152555"/>}} (Has *ID*) 3) Empty String ({{""}}) {{LiteralExpression}} {code} <dmn11:literalExpression id="_8d494cba-437c-46d6-ab72-7d5a743335f0"> <dmn11:text>""</dmn11:text> </dmn11:literalExpression> {code} -- This message was sent by Atlassian Jira (v7.12.1#712002)
