| Summary | 0045562: Messages, translations and lists for all modules are loaded from the database every time WebPOS is accessed or refreshed in HA | |||||||||||
| Description | Messages, translations, and lists for all modules are loaded from the database every time WebPOS is accessed or refreshed in High Availability instances As part of the initial loading steps of WebPOS, there are some pre-render actions that include loading all the messages, translations, and lists. This information is not cached so the same results are loaded from the database many times. When having two nodes for the Application Server, when we login back office on node-A, and update the translation, only node-A Labels Map cleared. The translations only affect the tills linked to node-A, the tills linked on Node-B will not be affected. | |||||||||||
| Steps To Reproduce | - Add a breakpoint in org.openbravo.mobile.core.login.LabelsComponent in functions getLabels() in line 'for (Object[] qryTrlObject : qryLists.list()) {' - Load the WebPOS login screen (the breakpoint is hit) - Refresh the page (the breakpoint is hit again) - Load the WebPOS login screen from another computer (the breakpoint is hit again) | |||||||||||

We are changing this issue to design defect. Translations are considered "sources" in OB, and that is why they are cached. It is true that as part of the caching mechanism we also introduced an event handler to reset the cache whenever possible, but this didn't change the fact that the correct way to apply a translation in a production environment in Openbravo is by installing a translation module, and this has always required a system restart. Changing this rule (so essentially removing the cache as there is no way to properly reset it in a HA environment), would be worse decisions overall than removing this limitation because of the performance penalty they would introduce, so we have decided not to change it for now. |
