Hi there,
according to Bonita 5.X documentation:
Use the simple button on a form to call a Java script.
By doing this...
Click on the Details panel > General tab > Options pane and enter the Java script in the HTML attributes field.
Unfortunately Bonita 6.X documentation doesn't make any reference to this widget...so I use 5.X
First question...
is "Java Script" (as written) Java code or JavaScript (one word), I'm assuming the latter as I believe you can also use jQuery on the button...
