Fixes

Designer

• Fixed a memory leak in the Desktop Preview
• Fixed a memory leak in the UI Editor
• Fixed an issue where Web Preview performance degraded over time
• Fixed a potential exception that could occur when using the redo action while setting actions in the drawing view definition panel
• Fixed a potential exception that could occur when editing a template in the UI Editor

Model

• The $numberBetween() function works properly when using the optional parameters
• Fixed a potential exception when the $listToString() function contains a null value

Views

• Charts
  • Fixed a potential exception that could occur when no integrator data is used in a chart view
  • Fixed a potential exception that could occur when a data point is not mapped to a model element
  • Fixed an issue where the chart did not fit properly
  • Fixed occasional synchronization issues with drawing views
  • Fixed a potential exception that could occur when the x value of a data point is null
  • Fixed an issue where nonnumerical x values show strange results

• Drawings
  • Fixed an issue where tooltips could appear away from the correct drawing element
  • Fixed a tool selection issue after using the Delete key
  • Fixed a potential issue in web applications where node images could be missing in rare situations
  • Fixed a potential exception that prevented SVG images from loading in web applications
  • Fixed an issue where mouse actions generated unnecessary server requests in web applications
  • Fixed an issue where drawing margin spacing was ignored
  • Fixed a potential exception that could occur when applying an undo action after deleting all elements in a web application
  • Fixed a hit-testing issue in image map applications
  • Fixed an issue where hit-testing did not work on visual cues in image map views
  • Fixed an issue where the viewport was empty after using the Go to Child action several times
  • Fixed an issue where connectors and labels were moved after unrelated changes

• Maps
  • Fixed an issue where markers are placed in the wrong position
  • Fixed a potential exception when selecting a tool in the toolbar

Integrators

• Fixed a SQL integrator issue that could occur when retrieving the quote type using a connection pool
• Fixed a potential infinite loop when refreshing an Excel integrator
• Fixed a potential exception in the text integrator when handling data conflicts

Licensing

• Fixed an issue where automatic user registration could fail for an already registered user
• The licensing system now works more efficiently in terms of application response when connection to the Tom Sawyer license server experiences interruption

Issues

• During development, if you recompile your custom code, you may need to restart the Designer, reopen the project, and preview your application again.
• To use a Google Map view within a deployed application, an API key is now needed. To add this into a Tom Sawyer Perspectives project, get the API key from developers.google.com, and then set the Client ID preference of your map view to "&key=YOUR_API_KEY".
