Adding multiple watchers to a task with a postfunction

[Rebecca haviv]

I have successfully used the following script to add multiple users as watchers to a task as a post function of a transition:

function SetWatchers() {

if(field1 == "ABC")

    watchers = addElement(watchers, "xyz1");

}

When I tried to add different options as below, I recieive an error which says "Encountered else in line xxx. Was expecting <EOF> :

   else {

if(field1 == "DEF")

    watchers = addElement(watchers, "xyz2");

    } else {

if(field1 == "GHI")

    watchers = addElement(watchers, "xyz3");

}

What am I missing?

The answer is to remove the "else" from the script and it works fine.

Some braces, try this:

if(field1 == "ABC") {
    watchers = addElement(watchers, "xyz1");
}  else { 
    if(field1 == "DEF") {
    	watchers = addElement(watchers, "xyz2");
    	} else {
		    if(field1 == "GHI") {
		        watchers = addElement(watchers, "xyz3");
		    }
    	}
    }

HTH,

The additional brackets returned more errors, but removing "else" did work.

A follow-up question - do you know how I can define more than one watcher?

watchers = addElement(watchers, "xyz1" + "xyz2"); does not work and does not add any watchers at all.

if i put

if(field1 == "ABC")

    watchers = addElement(watchers, "xyz1");

    watchers = addElement(watchers, "xyz2");

} {

if(field1 == "DEF") {

    watchers = addElement(watchers, "xyz3");

}    

The additional watcher is added to ABC, but also to DEF and any subsequent field1's.

What several errors do you get? Create an array with the watchers you want to add and then use arrayUnion  to add them all to watchers.

Multiple Users: I tried by calling a string where I defined users per each option for field one, but that behaved the same way as just adding another user to the the Watchers = watchers = addElement(watchers, "xyz1" + "xyz2");  I will try creating an array tomorrow and get back to you.
