Custom field doesnt working for new Issue Type

Question

Hi Everyone,

I have created new custom field plugin extending SelectCFType. 
Custom field works properly for predefined Issue Types (example : Bug,Task,Test etc) 
but when i create a new issue type and add my new custom field to that issue type. 
My options doesnt load and it renders no options.

When i check the log file i see this exception below;

/secure/admin/ConfigureCustomField!default.jspa [webwork.util.ValueStack] METHOD: "viewHtml", exception: 
java.lang.NullPointerException

com.atlassian.jira.issue.customfields.CustomFieldUtils.buildParams(CustomFieldUtils.java:446)

com.atlassian.jira.plugin.customfield.CustomFieldTypeModuleDescriptorImpl.getViewHtmlByValue(CustomFieldTypeModuleDescriptorImpl.java:181)

com.atlassian.jira.plugin.customfield.CustomFieldTypeModuleDescriptorImpl.getDefaultViewHtml(CustomFieldTypeModuleDescriptorImpl.java:174)

com.atlassian.jira.issue.customfields.config.item.DefaultValueConfigItem.getViewHtml(DefaultValueConfigItem.java:29)

com.atlassian.jira.issue.fields.config.FieldConfigItemImpl.getViewHtml(FieldConfigItemImpl.java:29)

What is the reason for this NullPointerException ? Have anyone help me ?

Thanks

Thank You Thomas,

I found the problem source.

FieldConfig fieldConfig = null;

if(issue == null)

{

fieldConfig = field.getReleventConfig(new SearchContextImpl());

} else

{

fieldConfig = field.getRelevantConfig(issue);

}

if i implement like this fieldConfig value becomes null and velocity renders nothing.

I changed it at below, by giving specific IssueTypeID i solved the problem.

FieldConfig fieldConfig = null

if(issue == null){

fieldConfig = field.getRelevantConfig(new IssueContextImpl(null,issueTypeID));

}else {

fieldConfig = field.getRelevantConfig(issue);

}

Is there any another effective way ? Thanks your care

Batuhan,

Do you think you didn't configure the custom fields correctly? Is there anything  special about your custom fields I need to know?  I would suggest a quick test. Remove your custom  fields from the issuse then add 1 custom field of the built-in types shipped with JIRA.  Keep track of the steps you took. I would not suggest using a global context to make sure you have the right steps. If the new custom field shows up as expected in JIRA, then use those steps to add your custom fields back to the project. Follow this documentation:

https://confluence.atlassian.com/display/JIRA/Adding+a+Custom+Field

Once we know custom fields can be installed corretly and if the problem is still there then look more closely at the design and coding of your plugin.

Have you followed the create a custom field plugin for JIRA before succesfully?

Thank Thomas,

velocity file is located properly because while addind custom field, if i select "any issue type" there is no problem.

I tried, i selected "any issue type" and added new custom field then i modified its configurations to any other issue type there is no problem.

The problem at the creation of custom field; it doesnt work issue types except "any issue type".
