Talend Data Mapper functions disappeared

[TRF]

Hi,

Using Talend Cloud Data Management Platform (Version 7.1.1 Build id: 20181026_1147).

My functions tab in Talend Data Mapper is empty (all functions disappeared)  

Everything was OK when I started to use TDM but suddenly they all disappeared.

Since, as soon as try to do something within tHMap such as mapping one input field to the corresponding output, I got error messages like this one:

Function SimpleLoop not found

Also, mapper properties tab display errors such as:

Error parsing expression
Caused by: Function SimpleLoop not found

Also, modifications made into the tHMap component cannot be saved because of these errors.

Is there any procedure to solve this problem or do I have to fully reinstall the Studio?

Thanks.

Functions come back after restarting Studio twice...

Apologize, I was connected to a fresh install for which functions are presents.

On the previous installation (same version for both), functions are still unavailable.

If anyone knew what I have to do to solve this case...

Thanks.

Hi TRF

Kindly let me know what are the step you have taken.

I have Talend 7.1.1 version install. Talend data mapper function were available. Now there is no function available in Talend Data mapper.

I have reinstalled the Studio.
One of my colleagues had the same issue but functions come back we don't know how...
Sounds like a bug but not still reported.

Thanks for update.

I close the Talend studio and clear all cache and temp files. Then restarted machine. After that again clear cache and temp file.

Then open Talend studio, after that all function are visible.
