tMap strange null pointer error

[vapukov]

Hi all,

just maybe somebody meets with similar case:

Source structure:

Next tMap code, works as expected:

row1.event.equals("TEXT")?
null
:row1.validAfter==null?
null
:Long.valueOf(TalendDate.formatDate("yyyyMMddHH",row1.validAfter) ) 

but similar extended construction:

row1.event.equals("TEXT")?
null
:row1.isPermanent==1L?
-1L
:row1.validUntil==null?
null
:Long.valueOf(TalendDate.formatDate("yyyyMMddHH",row1.validUntil) ) 

not!

each part of wrong code work fine, and current solution - 

replaced by SQL CASE at source for validUntil:

row1.event.equals("TEXT")?
null

tMap for out.validUntil_Long

row1.validUntil==null?
null
:Long.valueOf(TalendDate.formatDate("yyyyMMddHH",row1.validUntil) ) 

tjavaRow

if (row1.isPermanent==1L) {
out.validUntil_Long = -1L;
}

3 step work as expected, but all together - not

Java 8, Windows

solutions it work well, just interesting - why? is it an error in the my IF code, error in talend or java version specific issue?

I can't see anything immediately obvious I'm afraid. The only thing that looks like it might lead to a null pointer exception is the row1.event.equals("TEXT") code. However, your working solution has this as well.

I will test it later, what source of error - mix of types or construction

I have multi conditions constructions for string only and all work as expected

at the same time I have working constriction like:

condition?
(condition? (condition? true : false) : false)
:(condition? true : (condition? true : false))

and it works with different types

so need to find a time and simulate test cases 

Thank you for the answer Richard!
