Jørgen Tjernø updated JENKINS-12802:
------------------------------------
Assignee: (was: Jørgen Tjernø)
Component/s: (was: jenkins-plugin-runtime)
Removing the (poorly name) jenkins-plugin-runtime from the component list of
this bug. Jenkins-plugin-runtime deals with plugins in Ruby etc, not Java.
Sorry for the confusion!

> When defining a select box like this:
> {code:xml}
> <f:entry title="Version Control System type"
> field="vcs">
> <f:select/>
> </f:entry>
> {code}
> and validating the value through a
> {code:java}
> int i = 0;
> public FormValidation doCheckVcs(@QueryParameter String value) {
>
> System.out.println(i + ": value: " + value);
> i++;
> try {
> VersionControlSystem.valueOf(value);
> return FormValidation.ok();
> } catch (IllegalArgumentException ex) {
> return FormValidation.error("Please select one of the Version Control
> Systems.");
> }
> }
> {code}
> method, it can be observed that the validation method is called two times
> when opening the configuration menu (http://localhost:8080/configure). The
> first time, the correct default value, i.e., the selected item's value, is
> passed to the validation method. The second time, no data is passed in (see
> following code listing for output).

> 0: value: MERCURIAL
> 1: value:
