Populate select widget from a DB with Bonita Open Solution 6.4.2
I can't see the video because of my company proxy.
To populate a form with a database you need 2 task. In the first one, you add a database connector to select the data you need. In the second task, you use the data that you get to set the initial values in your form.
You don't need to uninstall it. You just need to install java 1.7 (if you don't have it) and change Bonita configuration. You can change the configuration in "Preferences", choose "Java" and add your java 1.7.
If the user need to choose a value before the connector, you need to create two distincts task. A first one where he choose the value. A second one where you use the connector. Using data will be your third task.
