You CAN’T throw an error or errors from a cfscript without defining your own throw function. But this is pretty easy to do. Somewhere else in your code, just write a <cfunction name=”throw” etc. and in this function just put a <cfthrow tag that throws the error you want to be thrown. A good practice would be to include a throw function in a utility cfc that you could invoke wherever you needed to throw an error in a cfscript.<\/p>\n

See the example code below. Note the interesting syntax for catching in a cfscript where you do catch(ERRORTYPE CFCATCHVARIABLE). So catch(database e), catch(any e) would be some common ones. And then you could access e.Message, e.Detail, etc.<\/p>\n

try
\n{
\n \/\/nothing below the throw would execute in this example.
\n \/\/But I left the rest for syntax reference.
\n somethingWrong=true;
\n if(somethingWrong){
\n throw("ExampleErrorType","Example Error message.");
\n}
\n \/\/save the reactor record without interfering with custom transaction
\n template1.save(useTransaction=false);
\n}
\ncatch (database err)
\n{
\n \/\/if the save fails and the error is a database error, return the error detail.
\n \/\/otherwise this error will need to be caught by the code calling this code.
\n return err.Detail;
\n}
\n<\/code><\/div>\n

If you want to do a rethrow, the following article has a great example.
