Comparing module-level attributes?

Hey all,

In my process of comparing two versions of the same module, I want to also compare module-level attributes - I wrote a function to do so.

void compareModuleAttributes(Module newer, Module older) {
 ModuleProperties newModProp
 ModuleProperties oldModProp
 ModuleVersion newModVers
 ModuleVersion oldModVers
 string attr

 newModVers = moduleVersion(newer)
 oldModVers = moduleVersion(older)
 getProperties(newModVers, newModProp)
 getProperties(oldModVers, oldModProp)

 for attr in oldModProp do {
  bool canMod = canModify(oldModProp.attr)
  if (canMod == true) {
   print "Attr: " attr "\n"
   newProp = newModProp.attr ""
   oldModProp.attr = newProp
  } else {
   print "Can't be modified: " attr "\n"
  }
 }
}

This works to find the module level variables and check if they're there, but the strange thing related to this is that none of these objects apparently can be modified - without the checks on it DXL throws errors claiming I have no access to those objects. Is anyone familiar with why this could be happening? I have access to each individual module which I am comparing and can successfully modify attributes to individual objects perfectly fine, but in DXL I have no access to module-level attributes. I'm even able to edit them in the GUI perfectly fine.

Thanks!

To modify a module level attribute you need to open the module in edit mode and use the Module handle to modify it. Like this: 

AttrDef ad; for ad in older do {
    bool isModule = ad.module;
    if (isModule) {
        string aName = ad.name; 
        module.aName = "Changed!"; 
    }
}

The module properties (getProperties) can only be used to read the properties of a module without opening it (which is considerably faster than opening the module to read the values).
