Hi,

dot (.) is a string concatenation operation, so line

data=cfunctions.getToken(data);

concatenates value of variable cfunctions (likely null) with returned array, which resulted in a null converted to string concatenated with array converted to string.

Best regards,
Victor

It all makes sense now. So easy when master explains it.

Thank you.

Can you replicate the problem in a simple to use function?

So it sounds like your problem is somewhere else.

Thank you for your reply. You are right. I tried your suggestion of simple function and it worked, so I tracked the problem to calling my function by library_name.function_name(), instead of just function_name().

I don't know if this other syntax of calling ( lib.fn() ) should work or not. I mean, in my code, the correct function was called even with lib.fn() syntax, and it did it's job, just the returning of an array was a problem. (I tested returning just a string and that worked fine).

Do you think this was just mistake in my code and it half-worked by accident, or is this a bug and I should report it somewhere? Anyway, thank you for your help.

Hi. I'm new to NetXMS and I'm loving it - it's great.
I'm using ver 2.0.2, and I'm trying to write function for a common task in script library which should return array. However returned value is string with text that looks like it is reference to the array or similar. So I have in one script library called cfunctions:

sub getToken(data) {
text=data[1];
delimiter=data[2];
position=data[3];
i=index(text,delimiter,position);
if (i==0) {
token=substr(text,position);
position=null;
} else {
token=substr(text,position,i-position);
position=i+1;
}
return %(text,delimiter,position,token);
}

then in another script i have:
use cfunctions;
t="aa,bb,cc,dd";
delimiter=",";
position=1;
array data;
data[1]=text;
data[2]=delimiter;
data[3]=position;
data[4]="";1

data=cfunctions.getToken(data);
...

If I try to use data[1] after call to my function I get error that object is not a container, if I print typeof(data) I get that it is string, and if I print variable data  I get someting like: [A@0x7ff74c30c9f9].

I also tried to create array in getToken function and populate it one by one (array retr; retr[1]=..., retr[2], .... return retr;) but I get same problem.

So how can I return and use returned array from my function.

Thank you.
