[resolved] UUID NumberFormatException

[Anonymous]

Hello.
I use Talend MDM community v5.4.1
I created a data model entity with a primary key of type UUID.
I selected "custom type" in simple type creation window and choosed UUID. Then an UUID model type appear in right panel, with the base type String.
When I deploy this and create a new item in Web user interface I have this error in console :
20:54:33,131 ERROR Failed to save item Person, For input string: "e375f6de-1b03-4169-acec-c7356472b185"
...
...
Caused by: java.lang.NumberFormatException: For input string: "e375f6de-1b03-4169-acec-c7356472b185"
e375f6de-1b03-4169-acec-c7356472b185 is the UUID generated for my primary key.
Did I missed something ??
Thank you

Hi,
Quite strangely, you have this error:

20:54:33,131 ERROR Failed to save item Person, For input string: "e375f6de-1b03-4169-acec-c7356472b185"

But no "Person" entity in your data model. Are you sure you posted the correct data model?

[Anonymous]

Hooo I posted the correct data model and the wrong error.
Sorry
For the "Task" data model the error is :

20:09:07,820 ERROR Failed to save item Task, For input string: "7053383c-c818-4fd3-be3b-7282d18504a7"

It seems that Talend wants to convert the string "7053383c-c818-4fd3-be3b-7282d18504a7" into a number ...
Thanks

Note that I translated the error message above in English.

Here's my guess: you first deployed the data model with an id typed as xsd:long (or xsd:integer... something that holds numeric values). Then you changed to UUID (a xsd:string based type) and redeployed the data model. But this doesn't change the column type in the database .
Please do the following:
* Check if the column type for "x_id" of the Task table is typed as numeric or string.
* If numeric: perform "alter table" statement to change the column to a varchar OR drop the whole database schema and restart MDM (MDM will recreate the schema from scratch).
: For conservative reasons, MDM only adds new stuff in the database but doesn't change existing database schema elements. For example, if you first deployed with an string Id and then change to numeric, the column will still be a string (because some values may already exist and some values can't be converted to a number).

Thank you very much.
My problem is SOLVED
I deleted all .db files in MDM server related to my container, I redeployed and it works !!
The ID was an AUTO_INCREMENT (int) before, when I changed it to UUID (String) the issue occured. Now I know how to deal with that.
