Process transitions in a state machine
Author: By
Last change: 2.4 2019-12-26
* 2.2 2019-10-22
* Updated eftec/MiniLang (dependency) from 2.9 => 2.12
* Updated eftec/pdoone (dependency) from 1.11 => 1.12
* Added dependency/documentstoreone (dependency) to 1.11 (it allows to use the filesystem as database)
* New methods setDocOne(), getDocOne()
* Now the library allows to use pdo (mysql database) or a file system (documentOne) for the persistence.
* Fixed a problem with the UI (it only executed the last job)
* Added changes to the UI. Now, it is possible to view and change the current job.
* Fixed a problem with the creation of table. Now the column TEXT_JOB is always created.
