How to properly convert single line text field to single select field.

Question

I need a single select custom field that contains the names of the project names in the Jira instance. There already exists a project picker but is not yet supported in the customer portal, thing that is a MUST for me.

What i have done so far:

* Created a Rest Endpoint that returns all the project names

@BaseScript CustomEndpointDelegate delegate
getProjects () { MultivaluedMap queryParams, String body,HttpServletRequest request ->

def projectList = ComponentAccessor.getProjectManager().getProjectObjects()
 def projects = []

for(String prName : projectList.name){
 projects.add(prName) 
 }

return Response.ok(JsonOutput.toJson(projects)).build()
}

//Works checking with Postman!

* Created a behaviour on the initializer

def test = getFieldByName("TEST")

test.convertToSingleSelect([
 ajaxOptions: [
 url : getBaseUrl() +"/rest/scriptrunner/latest/custom/getProjects",
 type: "GET",
 dataType: 'json',
 query: false, // keep going back to the sever for each keystroke 
 minQueryLength: 5, 
 keyInputPeriod: 500, 
 data : [
 label : "Pick a Task in project",
 ],
 formatResponse: "general",

],

css: "max-width: 500px; width: 500px",
])

The problem is that when i go to the converted single select customfield i can not see the results. Any idea?

The problem was that in the rest Endpoint i was sending a simple list, that could not be read from the Javascript on the behaviour. So in the Rest endpoint i added this code :

fullList = [
 items: projects.collect {
 [
 value: it,
 html : it,
 label: it,
   ]
  },
 ]

return Response.ok(new JsonBuilder(fullList).toString()).build()

And it Worked!!!!!
