Hello Nathan,

Yes, it's possible. By default, a form control gets its possible values from the schema. You can implement a SchemaManagerFilter [1] which reads a configuration file and contributes with values from that configuration file.

In Oxygen version 17.0 we've implemented such a SchemaManagerFilter ourselves [1] (it reads an XML configuration file) and we are already using it for DITA (amongt other frameworks). Inside the blog post Controlled Attribute Values for your DITA Project [3] you can see how this support is actually used for DITA and how you can extend it yourself (if you are using DITA).

Hi,
Would it be possible to get on-demand values for the form controls from a config file? For example: could we have set the values and labels of the oxy_combobox and oxy_editor to receive the string from a java code which reads a config file? If so, how could I go about doing this?

Thanks,

Nathan
