chartjs-wrapper-3.1 - Color class does not implement serialisable

[pvidhey9]

Currently using chart-js-wrapper version 3.1.0 in which the Color class does not implement serialisable

As a workaround, I extended the color class and implemented serialisable. The application runs fine in sequential manner. But in browser, on clicking back button, wicket application throws an error requesting for Parent color class to implement serialisable. Any suggestions for workaround? Or it would be great if you could release the latest version of the chart-js.wrapper with the changes. Any timeline specified? Really appreciate if you could help in this

RgbColorSerial is my local class that extends serialisable Error log: java.lang.RuntimeException: Could not deserialize object from byte[] at org.apache.wicket.serialize.java.JavaSerializer.deserialize(JavaSerializer.java:143) Caused by: java.io.InvalidClassException: com.alcatel.ngna.optical.gui.network.statistics.charts.RgbColorSerial; no valid constructor

Hello @pvidhey9, this issue has already been fixed in the latest snapshot release. It would be great if you could try it out and see if you still have issues. How to use it for both Maven and Gradle is specified at the bottom of our Readme.

Hi @maximAtanasov Thanks for the immediate response. You mentioned at the bottom to import the latest SNAPSHOT release(3.2.0), but it looks like it is not available in the maven repo. Also am using wicket 6 in my application, and the snapshot refers to wicket8. And I believe Color class is part of chartjs-wrapper package if am sure. Am I missing something here? If so,how do I get the corresponding change?

The snapshot is available at the following repo: https://oss.jfrog.org/artifactory/oss-snapshot-local. You should be able to use in your pom by addidng the following to the repositories block:

<repository>
      <id>snapshots-repo</id>
      <name>snapshots</name>
      <url>https://oss.jfrog.org/artifactory/oss-snapshot-local</url>
</repository>

Have a look at this page for an example: https://maven.apache.org/guides/mini/guide-multiple-repositories.html.

You can then just add the dependency like this:

<dependency>
  <groupId>de.adesso.wicked-charts</groupId>
  <artifactId>wicked-charts-wicket6</artifactId>
  <version>3.2.0-SNAPSHOT</version>
  <type>pom</type>
</dependency>

Hope this helps.
