Incoherence in links build project

[Ramón Rial]

I am developing a plugin to customize the build process. The jenkins 
version for the plugin is 1.466.

The plugin should show a custom page with fixed parameters and the normal 
parameters defined at job, before starting the build, without having to 
define (the fixed parameters) as parameterized build.

My problem is the following:
1) At jobs view (http://localhost/jenkins), the build link (schedule 
execution) renders:

<a href="job/jobName/build?delay=0sec">
...
</a>

And when I click the link sends EVER a GET request, although the job is not 
a parameterized build.

2) When I enter at job view in jenkins 
(http://localhost/jenkins/job/jobName), the build link renders:
* When the job isn't a parameterized build:

<a onclick="return build(this)" 
href="/jenkins/job/jobName/build?delay=0sec">
...
</a>

*There is an extra onclick="return build(this)", that launch a POST request.
*

* When the job is a parameterized build:
<a href="/jenkins/job/aaa/build?delay=0sec">
...
</a>
*There is no the extra onclick, so launch a GET request.*
*
*
To reproduce this problem you must:
Create a new project of any type (for example, Maven 2 project), that it is 
not a parameterized build. Save changes. Examine the *Build now* link. It 
has the extra onclick="return build(this)".
Now add a text parameter.  Save changes. Examine the *Build now* link. It 
hasn't the extra onclick="return build(this)".

I was examining the code hudson/model/AbstractProject.java (tag 1.466), for 
my plugin, the key is the method:

public void doBuild( StaplerRequest req, StaplerResponse rsp ) throws 
IOException, ServletException {
        BuildAuthorizationToken.checkPermission(this, authToken, req, rsp);

        // if a build is parameterized, let that take over
        ParametersDefinitionProperty pp = 
getProperty(ParametersDefinitionProperty.class);
        if (pp != null) {
            pp._doBuild(req,rsp);
            return;
        }

 

and following that, hudson/model/ParametersDefinitionProperty.java

public void _doBuild(StaplerRequest req, StaplerResponse rsp) throws 
IOException, ServletException {
        if(!req.getMethod().equals("POST")) {
            // show the parameter entry form.
            req.getView(this,"index.jelly").forward(req,rsp);
            return;
        }



So we see the req.getMethod.equals("POST") is the solution for my problem, 
but Jenkins render different links that launch GET call at jobs view and 
GET or POST call at job view. So my code is not working when I launch the 
build from job view.
