Last modified attribute

Hello,

I am quite new to DXL development, and I got this ideea that will make my life a lot easier... that being to be able to return the name (and date) of the last modified attribute? I was thinking that a trigger might be able to write this info into an attribute, but for me triggers are uncharted territory.

Does anyone have an ideea on how I can reliably return the last modified attribute and date of modification?

Help is much appreciated.

Dan.

Seems you want to search through History, something like this

History hst
HistoryType ht
string NameAttr = "", NameUser = ""
Date   datHist  = null
for hst in current Module do
{  ht = hst.type
   if (ht == modifyObject)
   {  NameAttr = hst.attrName
      datHist  = hst.date
      NameUser = hst.author
   }
}
print "Last modification\ton: " datHist "\tof: " NameAttr "\tby: " NameUser "\n"

Yes, avoid triggers for now.

Thanks Louie,

I just opened the page to post a solution i found, only to find that you answered my question.
What's funny though is that i used a very similar approach, using hystory, but I was thinking that the attribute "Last modified on" changes on any modification of an object and by comparing the history date with the last modif. i can assume that the respective attribute was the last one modified... anyway this is my code... feel free to comment
 

string checkMod(){
    string retVal = ""
 
        /*                      modify code here                */
        History h 
        string att 
        Date dt, lm
        for h in o do {
                HistoryType ht = h.type 
                if (ht==modifyObject) { 
                        att = h.attrName 
                        if (att == "Object Text"){
                                dt = dateOnly(h.date)
                                lm = o."Last Modified On"
                                if (dt == lm){
                                        print (o."Pool-ID")": "dt " vs " lm"\n"
                                        retVal = "changed"
                                }else{
                                        retVal = "same"
                                }
                        }
            }
        }
        return retVal
}
