I am trying to see configuration page of the KNIME node which i just published to my KNIME analytics tool.

Getting error "Error while creating node dialog for 'Readadwords': The configName must be a non-empty string" where Readadwords is my node dialog class which i created in eclipse.

Either in my Nodemodel or Nodedialog there is not a single config and i have defaulted it some or other string value.

Can some one help me where to look to fix my error and also please let me know if i can debug my knime plugin from eclipse rather than doing it in Analytics tool.

Debugging is explained in their developer guide, this page is the most relevant for that.

When you save your settings you have not specified the key for your config, that is what this error message is about. Like in this place assuming "" were used instead of "colName", I would expect a similar error message.

Issue is KNIME is not picking up the changes i have done to the code and i had to change version in plugin.xml file then it started working after copying new jar file to dropins folder of KNIME
