How to avoid errors raised by Java code which collecting RH_1 information
Hi All,
I need to track updates to Decision Tables etc., and created the following 2 Rules:
(1) Trigger that tracks saving to those Rule instances
(2) Logging Activity which is kicked by the Trigger above
Java code in (2) is below:
-----
PublicAPI tools = (PublicAPI) ThreadContainer.get().getPublicAPI();
// ClipboardPage stepPage = tools.getStepPage();
ClipboardPage clipboardValue = tools.findPage("RH_1");
// generate json from this template
com.pega.dsm.dnode.util.ClipboardPageJsonConverter converter = new com.pega.dsm.dnode.util.ClipboardPageJsonConverter(false);
converter.setPrettyPrint(true);
java.nio.ByteBuffer json = converter.asJson(clipboardValue);
String jsonString = new String(json.array());
// remove pxObjClass
jsonString = jsonString.replaceAll("\"pxObjClass\"\\s*?:\\s*?\".*?\",?\\s+", "");
content = jsonString;
-----
However, when these were Checked-In in the development environment, several problems(for example, as follows) occurred:

However, when these were Checked-In in the development environment, several problems(for example, as follows) occurred:
* It becomes impossible to import a language pack file. Import process will be not progress when the progress reaches 10%
* It becomes impossible to save rules such as Decision Table. Check-Out, Check-In, Save etc. raise errors
* When editing and saving parameters of "Property-Set" Method or "StringBuffer-Append" Method of Activities, a message is displayed that WrongModeException has occurred.
* Others ...
These bugs are not occured when commenting-out the Java source code in Method "Java", but I don't know what part is the problem, and how to solve it.
I would appreciate it if you could give me any advices.

Hello everyone,
The cause of the failures was identified, so I will report about it.
The cause was that NullPointerException occurred in Java code in Logging Activity.
The place is the 3rd line in Java code as following:
ClipboardPage clipboardValue = tools.findPage("RH_1");
According to Javadoc, tools.findPage() may return null value.
By performing a null check on this return value, the failures were resolved (At least, Import of Language Pack and Check-out, Save etc. of Decision Table can be executed without problems).
I hope that it will be helpful for those who are in trouble for the same reason.
Thanks a lot.
