This is a design limitation in RPE. A library script cannot use variables or data properties. If so, RPE will not use the script as library.

You should see the following message logged in console:
CRRPE3615E The script with id xx has data or variable references and cannot be used as a library.

Though you could use the library script function within try catch block, it is as good as calling a function that is not defined and hence it will be caught.

Yes Prasad, it is the limitation.

>>> I ran a quick test. Though I could use the library script function within try catch block, the output does not contain what is expected from the function.
Are the data properties evaluated correctly during document generation? or is just during the "Test script"?

Dmitry A. Lesin commented Aug 10 '18, 8:14 a.m.

Yes, thanks

I checked the same, and it's correct. And even, try...catch block isn't required if any variables are excuded because there's no error.

Did you check the "library script" property?



Thanks,

 Yes, exactly!

Checked library setting

And I can find and insert this function in another element by CTRL-SPACE.

 I'm working with RPE v6.0.5!

Dmitry A. Lesin commented Aug 07 '18, 12:31 p.m.
But I found that it catches an error that  "displayAllTCNames" is not defined when I try to use it. It's strange, may be there's a bug in RPE because I can not use it in the same template, isn't there?
Thank you

Could you try this in the text element? 

try{
    displayAllTCNames()
}
catch(e){
    //catch and just suppress error
}
