How to override a public function of com.atlassian.jira.web.action.admin.customfields.EditCustomFieldOptions in a JIRA customField plugin

[Kepio]

The isCascadingSelect() public function in com.atlassian.jira.web.action.admin.customfields.EditCustomFieldOptions is checking a custom field type is an instance of CascadingSelectCFType (a native JIRA custom field type).

I am writing a custom Field that does not ( and cannot) extend CascadingSelectCFType but is extremely similar ( it's a multi cascading select instead of simple cascading select) - as such, i'd like to re-define the isCascadingSelect function to check for either CascadingSelectCFType or MultipleCascadingSelectCFType - is that possible?

If not, what would be the best approach?

I figured out the approach by browsing the source code of https://studio.plugins.atlassian.com/svn/JDVP/tags/database-values-plugin-1.3/

The atlassian-plugin.xml definition pretty much gives the answer :

<webwork1 key="multiple-cascading-select-cf-type-configuration" name="Multiple Options Cascading Select Field Configuration">
		<description>Configuration for the Multiple Options Cascading Select Field Field.</description>
		<actions>
		    <action name="com.company.plugins.jira.customfields.config.EditMultiCascadingCustomFieldOptions" alias="EditMultiCascadingCustomFieldOptions" roles-required="admin">
        		<view name="input">/secure/admin/views/customfields/editcustomfieldoptions.jsp</view>
        		<view name="error">/secure/admin/views/customfields/editcustomfieldoptions.jsp</view>
        		<view name="confirmdelete">/secure/admin/views/customfields/deletecustomfieldoption.jsp</view>
        		<view name="edit">/secure/admin/views/customfields/editcustomfieldoptions.jsp</view>

        		<command name="configureOption" alias="ConfigureCustomFieldOptions">
            		<view name="error">/secure/admin/views/customfields/editcustomfieldoptions.jsp</view>
        		</command>
    		</action>
		</actions>
	</webwork1>

From there- you can:

• modify the jsp file EditMultiCascadingCustomFieldOptions extends EditCustomFieldOptions and overwrite my public function
• modify the templates directly if need be - in my case, I re-used the native ones
