error when testing an expression

[carlrees123]

Exception in thread "main" java.lang.Error: Unresolved compilation problems:  

comes up in red

does anyone think the expression is incorrect? -- no, so why the error?

upon exiting expression builder and run the job it works perfectly... known bug?

I was able to reproduce this when I put "Y" as the value for name2.  I finally found an example of how to use the expression builder Test feature in the documentation:

https://help.talend.com/reader/nXPtKhielAtSqFD6_f7~OQ/UiJEcAn2BxH5csEtuIR5pA

It shows that test values should not be wrapped in quotes, so I removed my quotes.  After that, the test started working and displays "Yes" in the output area.

Hi,

We usually use the Test! button to test a function.

The Test! button can't understand "Y" for your column value name2, you need to execute the job to see if the job works without any compilation error or Java error to locate your issue in expression.

Best regards

Thank you again cterenzi (Kudos to you for the post !!)

Great reply and good link to documentation (love the chuck Norris ref !)

I have found the issue and it IS A BUG in the Talend expression/function checker, the coder who wrote this did not check for a Var (variable) that has no name defined

I wonder if they also checked for variables that are reserved words?

see screen shot of blank variable !
