Array returns "undefined".

[Victor Ruiz]

Attempting to retrieve a list of CI's but the second Glide query returns undefined, what am I missing?

var appsArr = [];

var gr2 = new GlideRecord('task_ci');
gr2.addQuery('task', current.sys_id);
gr2.query();
while(gr2.next()){

appsArr.push(gr2.ci_item.toString());

}

var applications = [];

for(var i=0; i<appsArr.length; i++){

var gr = new GlideRecord('cmdb_rel_ci');
gr.addQuery('child',appsArr[i]);
gr.query();
gs.log(gr.parent); //RETURNS UNDEFINED
while(gr.next()) {

applications.push(gr.parent.toString());
}
}
current.addQuery('sys_id','IN',applications.toString());

use gs.log(gr.parent); inside the while block. 

you can not access value before the iteration 

var appsArr = [];

var gr2 = new GlideRecord('task_ci');
gr2.addQuery('task', current.sys_id);
gr2.query();
while(gr2.next()){

appsArr.push(gr2.ci_item.toString());

}

var applications = [];

for(var i=0; i<appsArr.length; i++){

var gr = new GlideRecord('cmdb_rel_ci');
gr.addQuery('child',appsArr[i]);
gr.query();

while(gr.next()) {

gs.log(gr.parent); 

applications.push(gr.parent.toString());
}
}
current.addQuery('sys_id','IN',applications.toString());

its returning null even though I can see the values of the array.

try now

var appsArr = [];

var gr2 = new GlideRecord('task_ci');
gr2.addQuery('task', current.sys_id);
gr2.query();
while(gr2.next()){

appsArr.push(gr2.ci_item);

}

var applications = [];

for(var i=0; i<appsArr.length; i++){

var gr = new GlideRecord('cmdb_rel_ci');
gr.addQuery('child',appsArr[i]);
gr.query();

while(gr.next()) {

applications.push(gr.parent.toString());
}
}
current.addQuery('sys_id','IN',applications);

Removing toString() only retrieves one value in the array.
