Regarding this issue, we have fixed the problem by adjusting the jsp
template
/system/modules/com.alkacon.opencms.formgenerator/pages/form.jsp
lines 85ff. (which should probably be moved into the Java classes, but we
just tried this for a quick fix directly in the jsp for now):

              [...]
		// loop through all form input fields 
		I_CmsField field = (I_CmsField)fields.get(i);
		
		// --- Begin: SYSVISION modification ---
		List items = new ArrayList();
                CmsMacroResolver macro =
CmsMacroResolver.newInstance().setCmsObject(cms.getCmsObject());
		Iterator it = field.getItems().iterator();
                while (it.hasNext()) {
                    CmsFieldItem curOption = (CmsFieldItem)it.next();
                    if (CmsMacroResolver.isMacro(curOption.getValue())){
                        String value =
macro.getMacroValue(CmsMacroResolver.stripMacro(curOption.getValue()));
                        items.add(new CmsFieldItem
(value,value,curOption.isSelected(),curOption.isShowInRow()));
                    } else {
                        items.add(curOption); 
                    }
                }
                field.setItems(items);
		// --- End: SYSVISION modification ---
				
		if(i==n-1)place=1; //the last one must close the tr
                [...]

This is the code of the DynamicFieldResolver implementation; but the field
still just doesn't get rendered when displaying the form.

package com.company.intra.controller.formgenerator;

import com.alkacon.opencms.formgenerator.CmsDynamicField;
import com.alkacon.opencms.formgenerator.CmsForm;
import com.alkacon.opencms.formgenerator.I_CmsDynamicFieldResolver;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

public class CmsDynamicFieldResolver implements I_CmsDynamicFieldResolver {

    protected final Log logger =
LogFactory.getLog(CmsDynamicFieldResolver.class);

    public String resolveValue(CmsDynamicField field, CmsForm form) {

        logger.info("DYNFIELD field.getType(): " +  field.getType() );

        // just for debugging - these values are already set in the webform
config itself
        field.setLabel("TEST");
        field.setMandatory(true);
        field.setValue("whatever");

        return "My value";

    }

}
