Hi Isomorphic,
Setup: SmartClient Version: v12.0p_2019-11-25/PowerEdition Deployment (built 2019-11-25)
please see this testcase:
BuiltInDS.java
BuiltInDS.html
animals.ds.xml
batchUpload.ds.xml
BatchUploadDMI.java
CustomValidator.java
animals.csv
What I expect that code should do:
First click on search and select the "animals.csv", and click upload. I would have expected that in the "Preview-Grid" the value of "commonName" in any row has the value "RESULTINGVALUE" due to the "CustomValidator"(And it indeed gets hit on "upload"-click).
But the values are still the same as in the "animals.csv".
If You click "commit", the values change to "RESULTINGVALUE".
What I need is that the resulting value is already set on "upload" and modify it on the client within:
and not on "commit".
I need that because I want to show different icons (on a fake field/ not implemented here) in order of the validation result without triggering a validation error. And the logic that calculates the icon is done on the server and can not be moved to the client.
Can You help me here to get this done?
Thanks in Advance,
Kind Regards
