Can I associate a new search template to an existing field type in JIRA?

[tommy guo]

In other words I want to write a new search template and have it be associated with an existing field type on JIRA such as the "select list" field, such that all custom fields that are created of type select list will have the option of using this searcher.

You need to write a "searcher" and implement it as a plugin. This refers to custom fields, but actually covers the searchers as well: https://developer.atlassian.com/display/JIRADEV/Custom+Field+Plugin+Module

The key here is that once you've written a searcher, you use the valid-customfield-type tag to tell Jira "and allow people to select my searcher for these field types". I must admit the only searchers I've ever written have been for my own custom fields, so I've bundled them together and never really tried to say "allow my searcher to be used by standard select lists", but I can't see why it wouldn't work.

So I would need the line:

"<valid-customfield-type

package="com.atlassian.jira.plugin.system.customfieldtypes" key="select" />"

in my plugin-xml file?

Yes, that's my understanding (as I said, I've not tried it, but that is exactly what I think the doc means)

Nic thank you for the reply, I've tried implementing this method however when I go to change the search template for select list fields my plugin is automatically disabled by the jira server and hence I can not change the search template to my custom one. The code I used inside the plugin was:

public

class MySelectSearcher extends SelectSearcher {

public MySelectSearcher(ComponentFactory componentFactory,

ComponentLocator componentLocator) {

super(componentFactory, componentLocator);

}

}

What's your best guess as to why it's not working?

[Nic Brough -Adaptavist-]

Hmm, I think it might be struggling with the extension of a core class that might not be intended for much extension. (I'm not a java developer, I'm not going to pretend I fully understand this in detail)

Here's what I've got that seems to work for a field that's a bit like a select list:

public class MySearcher extends AbstractCustomFieldSearcher implements CustomFieldStattable, SortableCustomFieldSearcher

{

private final SelectConverter selectConverter;

public MySearcher(SelectConverter selectConverter, FieldVisibilityBean fieldVisibilityBean)

{

super(fieldVisibilityBean);

this.selectConverter = selectConverter;

}

.....

Hey Nic , it seems that the class AbstractCustomFieldSearcher no longer exists in the current version of Jira. Does AbstractInitializationCustomFieldSearcher work just as well?

[tommy guo]

I got it to work by using

public

<font></font>

class MySelectSearcher extends SelectSearcher

{

{

super(JiraComponentFactory.getInstance(), new JiraComponentLocator());

}

}
