Update the project

Warning message will appear if existing project structure differs from uploaded one.

Dependency manager support for Java code

Dependency manager will propagate all imported packages from dependency modules. All imports will be inherited by module from its dependencies and import instructions are not required to be repeated.

Management page for Web Service application

OpenL Tablets Web Service application replaces the default page from CXF to contain all the deployed services with their methods in more appealing UI, removing not essential technical details and adding time stamp when the service was started.

Auto detection of Spreadsheet cell types

Spreadsheet table will autodetect the type of its cells with OpenL formulas in them. In previous versions OpenL Tablets always assumed that the type of formula was DoubleValue and explicit type definition for the cell was required in case of other type. By default the behavior of previous versions is used in this release. In future releases the default behavior will be changed to allow auto detection of cell types.

To switch on auto detection for the cells the new property “Auto Type Discovery” (autoType) for Spreadsheet table should be set to ‘true’. In future releases the property default value will be changed to ‘true’.
