Exception when calling an Action issued from a table which element has got id
of type Integer
---------------------------------------------------------------------------------------------
Key: BPM-301
URL: http://jira.andromda.org/browse/BPM-301
Project: Bpm4Struts Cartridge
Type: Bug
Versions: 3.2, 3.3
Environment: 3.3-SNAPSHOT but was also in the 3.2 release.
Reporter: Jean-Marc Collin
Assigned to: Wouter Zoons
I've got an ValueObject (VO) with an "id" of type Integer,
I've got a table in a FrontEndView (FEV) displaying a Collection of these VO,
On this FEV I've got several links forwarding to Struts Actions,
Some of these links are issued from the table and applied to selected VO
elements :
- @andromda.presentation.web.action.tablelink="myTable",
- @andromda.presentation.web.action.type=table,
- the link between the FEV and the Action has a parameter called "id" of
type Integer which represent the selected VO's id.
So with this configuration, Andromda 3.3 generates a Struts validation to
verify that "id" is an integer. Here is an extract of the validation.xml file :
<formset>
<form name="myForm">
<field property="id" depends="integer">
<arg position="0"
key="ucgerer.dossier.pret.afficher.lst.dossier.pret.detailler.param.id" />
</field>
</form>
...
This cause an exception because the Struts validation is searching for a field
named "id" which does not exists. The error is the following :

If the id is a String attribute, the problem disappear.
The solution could be not to generate form validation in the validation.xml
file for this kind of action (action on a table).
Thank's in advance.
