Version 3.1.10 of Obba brings the following changes:
- Improved startup of local server from Microsoft Excel.
Version 3.1.9 of Obba brings the following changes:
- Fixed a bug which resulted in a manually started server shutting down when the client disconnects. The server now keeps on running. Note: The behavior can be customized in the servers Obba.properties file.
- Fixed a bug which resulted in an error when creating an array consisting just on one element.
- Some improvements to error messages.
Version 3.1.7 of Obba brings the following changes:
- obGet makes a default conversion to a string (using the toString-method on the specific object), when calling obGet on an object for which no corresponding or suitable spreadsheet datatype is available.
Version 3.1.6 of Obba brings the following changes:
- Stability improvements to the OpenOffice version.
Version 3.1.2 of Obba brings the following changes:
- Ability to dynamically compile a class from Java source (provided as a spreadsheet string) and instantiate objects from it (using the spreadsheet function obMake): Obba now includes a utility class (info.obba.javatool.Compiler) which allows to dynamically compile a class from a string source. Obba's obMake accepts object handles to java.lang.Class object to specify the class. See "04 - Class to Object Demo" in the "Demos" folder.
Version 3.0.12 of Obba brings the following changes:
- Stability improvements to the OpenOffice version. In some situations an odt sheet failed to load external JARs through the spreadsheet function right after opening. A forced manual re-calculation was necessary. (Note that it is no longer recommended to load a JAR via a spreadsheet function. Instead place all JARs side by side to the server and lauch the server manually).
Version 3.0.8 of Obba brings the following changes:
- Rewrite of Obba add-ins for Microsoft Excel and OpenOffice / LibreOffice / NeoOffice.
- Allows to run the Obba server Java virtual machine in a separate process (run "java -jar Obba.jar").
- Allows to run the Obba server Java virtual machine on a remote machine (edit the ip address in ObbaClient.properties).
- Easier creation of java.util.Date form Excel Date / OpenOffice Date using obMake(;"Date";...).
- Added conversion from java.util.Date to Excel Date / OpenOffice Date via obGet.
- The Excel functions obLoadObjects / obSaveObjects were renamed to obLoad / obSave respectively (to create compatibility with the OO implementation).
- Added support for Excel 2010 64 bit.
- Worked around a problem resulting in Obba Control Panel not showing up under OS X.
- Fixed a bug resulting in a hang of OpenOffice (once) after installing Obba.
- Improved error / exception handling: much clearer log output of Java exceptions.
Version 2.2.15 of Obba brings the following changes:
- The Obba properties file allows to disable the access to the Obba control panel via "controlpanel=disallow".
- The Obba properties file allows to hide the Obba menu in Excel via the "menu=hide".
Version 2.2.10 of Obba brings the following changes:
- Obba for Excel now prints the calling spreadsheet cell to the log file, when a Java exception occurs. This may come in handy when debugging spreadsheets.
Version 2.1.8 of Obba brings the following changes:
- Complete rewrite of Obba logging.
- Added a log window to the Obba Control Panel (enable it via Window -> Show Log Window)
- Many improvements to the diagnostic output.
Version 1.9.34 of Obba brings the following changes:
- Fixed a problem which prevented loading of some classes. The current thread's context class loader was null. This appears to be a problem with the Java plugin. A workaround was created. Note: This problem resulted in the XMLDecoder not working.
- Fixed a problem which prevented installation of Obba for OpenOffice.
- More improvements for OpenOffice
Version 1.9.29 of Obba brings the following changes:
- Arrays of objects can be created using obMake with a class name of ClassName[] where ClassName is the component type (see documentation for an example).
- Added a demo sheet showing how to access data from finance.yahoo.com. Include the Java source code for the class handling the web access.
Version 1.9.13 of Obba brings the following changes:
- Added a window to the Obba Control Panel which visualizes the objects and their dependencies in a graph. The dependencies are determined by the objects used during construction an object.
- Improved the handling of transient object handles.
Version 1.8.26 of Obba brings the following changes:
- Invocation of static methods (class methods) now uses dynamic method lookup (before this was only supported for methods on objects)
Version 1.8.25 of Obba brings the following changes:
- Bug fix. Accessing elements of an array of primitives returns a primitive (before the wrapper object was returned)
Version 1.8.21 of Obba brings the following changes:
- Access fields of an object directly through a spreadsheet function call using 'obCall'. In this case the method name has to be dot + fieldname (e.g '.myMember').
- Access elements of an array through a spreadsheet function call using 'obCall'. In this case the method name has to be '[]' and the argument of the call is integer specifying the index. Element of multi-dimensional arrays can be accessed likewise.
- Vector arguments can be passed as arbitrary ranges (columns, rows or two dimensional ranges which are then flattened using row major).
