Hi,

I keep getting the following errors when attempting to use tDenormalize in TOS 4.0 (and also 4.1):

"This component depend on component tArrayIn, but it's not exist." (The error message really is grammatically incorrect.)
"OnRowsEndStructtDenormalize_1 cannot be resolved."

I thought it was the fact that I was trying to use a tMysqlInput as the input into the tDenormalize, but even when I switched to a very simple tFileInputDelimited and set everything up like the RG example, I get the same error. Upgrading to the latest TOS didn't fix anything either.

What am I missing?

Please advise ASAP.

Best regards,
LC

Hi LG
I test it on v4.1.x and it works, please upload some screenshots of your job.

Best regards

By the way, the "This component depend on component tArrayIn, but it's not exist." error shows up as soon as I drag the tDenormalize component from the Palette to the Design grid. So I get a red X that never goes away on the tDenormalize component.

The "This component should have input link(s)." warning goes away as soon as I connect the tFileInputDelimited.

Ugh.
I solved it.
Restarting didn't fix it.
Upgrading didn't fix it.
There was nothing wrong with how I set up the job.

I decided to see what would happen if I created a new project and tried using tDenormalize there. It worked fine, so I determined there must be something wonky within the current project I was using.

I then went back to my current project and compared the Project properties. I noticed that under File > Edit Project Properties > Designer > Palette Settings, the new Project had Technical/tArrayIn, etc. under the Hide Column, while my current Project had it under the Show column. I don't actually see the Technical component group in my Palette anyway, so I moved it to the Hide column as well to see if it made a difference. It did not. I moved it back to the Show column, and the Generation Engine started re-running itself, the Technical folder actually did show in my Palette, and the red X next to my tDenormalize finally disappeared.

I tried to run my basic tFileInputDelimited --> tDenormalize --> tLogRow job, but then tFileInput Delimited suddenly had an error about "org.talend" being undefined or something. I moved some more folders back and forth in Palette Settings, and next time I ran the job, it was finally successful.

I don't really know why the Generation Engine wouldn't have picked up the correct Palette settings from the beginning. I do know the project has been upgraded through a few TOS versions under both Mac and PC.

In any case, thanks anyway,
LC
