Improving error messages from backend to cell popover ------------------------------------------------------ Key: DROOLS-3992 URL: https://issues.redhat.com/browse/DROOLS-3992 Project: Drools Issue Type: Enhancement Components: Scenario Simulation and Testing Affects Versions: 7.22.0.Final Reporter: Yeser Amer Assignee: Yeser Amer Priority: Minor Labels: ScenarioSimulation, drools-tools Aim of this ticket: - Improve error messages sent by server to the cell popover in case of specific errors: eg. [~kkufova]: I noticed that Impossible to parse as boolean message keeps getting displayed instead of an actual help. For example, I used falsee instead of false. I think in this case we definitely need The expected value is 'false' but the actual one is 'falsee'. Another scenario: if the expected value is null but I enter [] instead, the error message is Error with this value: Impossible to parse as boolean. It doesn't say anything about the actual value being null. - Improving exceptions handling related to this part: at the moment, any type of exception could be sent to the popover (eg. OutOfMemory). Only a subset should be managed. Related to https://issues.jboss.org/browse/DROOLS-3838
