Init of data in widgets

Greetings all,

Regarding OAD, i built 2 widgets to test context messaging:

- first one is of type "list" and uses a static list as data service

- the second is a form widget that uses 2 M3 API CMS100MI to retrieve data in the ERP (based on 1 delivery: quantity to pick, quantity moved to pack location and quantity already packed)

Delivery 548 is fully packed but not moved on PACK location => second field is empty. Same for this other delivery below:

Delivery 159 has been partially picked and 4 PCE moved to PACK location

When clicking again on another row of the first widget, Qty on PACK loc. remains:

This second field uses a data service that may not return any record. 

How can i initialize properly this field ? Bug ?
