Issue/Introduction
A custom action created with the SDK was working fine with agent version 6.7 or earlier
But since upgrade of agent to version 6.8.*, SDK custom action fail with error :
Error occurred during action execution: _log
On Agent in log nolio_all.log there are these lines :

Environment
Release Automation 6.8, 6.9
Cause
In Release Automation 6.7 and earlier, NolioAction interface has _log member defined like this :
static org.apache.log4j.logger _log
In SDK documentation :
But since Release Automation 6.8, _log member has been removed from NolioAction.
The field _log was removed from the interface NolioAction intentionally and permanently, by architectural reasons. Having such static fields in interfaces is a generally bad pattern, making confusions and complications in further development.
Resolution
The solution is to change the custom SDK codes by adding a member _log for every action class
Add this line :
import org.apache.log4j.Logger;
And create the logger field
protected static transient Logger _log = Logger.getLogger([ActionClassName].class);
In the end we should get something like that:
package my.package.name
import com.nolio.platform.shared.api.*;
import org.apache.log4j.Logger;
/**
*
* <p>Date:
*
* @author
*/
@ActionDescriptor(
name = "Class Name",
description = "",
category="")
public class MyClassName implements NolioAction {
private static final long serialVersionUID = 1L;
protected static transient Logger _log = Logger.getLogger( MyClassName.class);
@Override
public ActionResult executeAction() {
return new ActionResult(true, "Action completed");
}
}
Another solution is to apply patch 6.8.4 and 6.9.1 as _log member will be added again in the class NolioAction.
Additional Information
Example :
- This class was created with SDK and working fine with agent 6.7 but no more with agent 6.8 due to line "_log.debug ("This is a log writing from custom action");"
package com.mycompany.testjy7;
import com.nolio.platform.shared.api.*;
/**
* An example Nolio action
*
* <p>Date: Mar 12, 2024</p>
*
* @author jy
*/
@ActionDescriptor(
name = "Hello Action",
description = "This action receives a name and returns a welcome greeting.",
category="Greeting.Hello" /* Parent category is greeting, and sub category is Hello */)
public class testjy7b implements NolioAction {
private static final long serialVersionUID = 1L;
@ParameterDescriptor(
name = "Username",
description = "The name of the user",
out = false, // Whether parameter is an output.
in = true, // Whether parameter is an input.
nullable = true, // Whether parameter can have a null value. Must be true if a default value exists.
defaultValueAsString = "jy", // Used as the default value of this parameter.
order = 1 // Indicates the order of the parameters in the UI
)
private String username = "jy";
@ParameterDescriptor(
name = "Welcome String",
description = "Welcome greeting",
out = true,
in = false)
private String welcomeString;
@Override
public ActionResult executeAction() {
if ("error".equalsIgnoreCase(username)) {
return new ActionResult(false, "Error occurred. sorry!");
} else {
welcomeString = "Hello " + username;
_log.debug ("This is a log writing from custom action");
return new ActionResult(true, "Hello " + username);
}
}
}
And here the updated code to make it working with Agent 6.8 and higher
package com.mycompany.testjy7;
import com.nolio.platform.shared.api.*;
import org.apache.log4j.Logger;
/**
* An example Nolio action
*
* <p>Date: Mar 12, 2024</p>
*
* @author jy
*/
@ActionDescriptor(
name = "Hello Action",
description = "This action receives a name and returns a welcome greeting.",
category="Greeting.Hello" /* Parent category is greeting, and sub category is Hello */)
public class testjy7b implements NolioAction {
private static final long serialVersionUID = 1L;
protected static transient Logger _log = Logger.getLogger(testjy7b.class);
@ParameterDescriptor(
name = "Username",
description = "The name of the user",
out = false, // Whether parameter is an output.
in = true, // Whether parameter is an input.
nullable = true, // Whether parameter can have a null value. Must be true if a default value exists.
defaultValueAsString = "jy", // Used as the default value of this parameter.
order = 1 // Indicates the order of the parameters in the UI
)
private String username = "jy";
@ParameterDescriptor(
name = "Welcome String",
description = "Welcome greeting",
out = true,
in = false)
private String welcomeString;
@Override
public ActionResult executeAction() {
if ("error".equalsIgnoreCase(username)) {
return new ActionResult(false, "Error occurred. sorry!");
} else {
welcomeString = "Hello " + username;
_log.debug ("This is a log writing from custom action");
return new ActionResult(true, "Hello " + username);
}
}
}
