Exception on Create Node Policy while uploading new version action

[hiten_rastogi1]

Hello,

I am facing exception on Create Node Policy in my project. In my behavior class I am trying to fetch the <strong>node-dbid</strong> of the doc. I am facing this issue when I try to upload the new version of the document. For e.g. I upload a normal document and change it's type to {my_type}, after editing the document properties,I have another behavior implemented OnUpdatePropertiesPolicy, I am able to generate the all the required fields including node-dbid but, when I try to upload the new version of the document from the Document Actions I get an exception.

Below is my code and exception.

<strong>custom-model</strong>

<!– DBId of the node –>
            <property name="evl:docId">
               <title>Doc Id</title>
               <type>d:text</type>
               <multiple>false</multiple>
               <index enabled="true">
                  <tokenised>false</tokenised>
               </index>
            </property>

Hello Hiten,

Try to change the <strong>NotificationFrequency.TRANSACTION_COMMIT</strong> to <strong>NotificationFrequency.EVERY_EVENT</strong>.

Thanks Sujay,

Your solution is working pretty well.
