Pentaho Data Access Wizard
Role in this project:Back-end Developer
Back-end DeveloperContributions:42 commits in 1 year 7 months
Contributions summary:Jeffrey's commits primarily focused on addressing issues related to data source access within the Pentaho Data Access Wizard. They modified code to restrict access based on user permissions and prevent unauthorized access to the data source wizard. The changes involve the modification of Java files within the `src/org/pentaho/platform/dataaccess/datasource/ui/selectdialog` and `src/org/pentaho/platform/dataaccess/datasource/wizard` packages, which suggests that their work directly impacted the data access and security aspects of the application. The user also added conditional visibility to the UI elements based on the access permissions.
