#2167 ReferenceError: "importPackage" is not defined in <eval> at line number 2

[Henk van den Akker]

I could reproduce bug #2153, but did not know how to reopen it.

Freemind version: 1.3.11
Java version: 1.8.0_05
Mind you, not reproducible with older java versions, e.g. 1.7.0_65.

The actual error is:

"Error in Script"
"ReferenceError: "importPackage" is not defined in <eval> at line number 2"

There are two ways to reproduce this error:

1 Select a node or create a new node and type '=' to start a formula.
2 Select a node and choose from the menu: Tools -> Edit script...

As far as I can see the error has no impact on functionality, i.e. you can successfully enter your formula or add or edit your script.

This error did not show up in the Freeplane log file.

Ok, the Java version was the missing information - thanks for pointing that out. Unfortunately our new bug tracker has no field for the concerned Java version. Maybe we could add it.

I tracked the error down to the JSyntaxPane library that we use for the editor. I describe it to some more detail since I don't know the best solution right now and maybe Dimitry or Felix could help.

Our JSyntaxPane version includes the following script:

jsyntaxpane/src/main/resources/META-INF/services/jsyntaxpane/scripts/insertdate.js

which is configured in

jsyntaxpane/src/main/resources/META-INF/services/jsyntaxpane/syntaxkits/javasyntaxkit/config.properties

It contains the statement

importPackage(java.util);

Unfortunately this statement is only supported by the Rhino JavaScript engine that was included into Java 6 - 7 but not by the new Nashorn JavaScript engine in Java 8.

See http://stackoverflow.com/questions/22502630/switching-from-rhino-to-nashorn

We have to decide how to proceed with this problem in JSyntaxPane. We could fix it in our included library or switch to a newer JSyntaxPane version.
