When pushing a content item through a workflow, the user is presented with a workflow comment UI with a textbox. We need to increase the number of allowed characters to something closer to 1024 characters. The number of allowed characters is not configurable under Rhythmyx 6.7.
The best option would be to make this a configuration option, defaulting to 255 characters. Otherwise, we’ll probably make another feature request at some point in the future, asking you to increase the allowable size again.
