Reloads going missing at each row global variable
When using reload at each row with globalMap Key (as seen in the next screenshot), Talend allows you to cut and paste expressions into the globalMap variable, but when you go out of the tMap component and come back in again, you will see that it hasn't changed.
How to do it...

- The second (and preferred option) is to edit the expression in the Expression editor tab. This method allows any expression to be coded to ensure that the variable is set correctly, as shown in the next screenshot:
