Hi Spatruni,

You can use customFieldObject.updateValue() method to update the customField Value.

CustomField project = customFieldManager.getCustomFieldByName("Name of your custom Field");

project.updateValue(FieldLayoutItem arg0, Issue issue, ModifiedValue arg2, IssueChangeHolder issueChangeHolder)

where, FieldLayoutItem can be null or can give value for FieldLayoutItem.

Issue issue = issue object in which you want to update the value of customField.

ModifiedValue arg2 = new ModifiedValue(oldValue of customField, newValue which you want to update)

IssueChangeHolder issueChangeHolder = new DefaultIssueChangeHolder()

I think this will work for you.

Save the project id instead of saving the entire Project object into the custom field value.

Getting the following exception with id.

java.lang.ClassCastException: class com.atlassian.jira.issue.customfields.impl.ProjectCFType passed an invalid value of type: class java.lang.Long

Jobin Kuruvilla [Adaptavist]

Try the id as String, not Long.

Hi Jobin, The result is same, classcastexception again.

CustomField originalProduct = componentManager.getCustomFieldManager().getCustomFieldObject("customfield_10031");
originalProduct.createValue(issue, String.valueOf(componentManager.getProjectManager().getProjectObjByKey(pKey).getId()));

java.lang.ClassCastException: class com.atlassian.jira.issue.customfields.impl.ProjectCFType passed an invalid value of type: class java.lang.String

srinivasp

I guess this requires ProjectCFType object as parameter but i donno how to get a refeference of that type. Tried in various ways for getting the ProjectCFType referecne but not found the reference. Could someone tell me how to get a ProjectCFType reference for a project or suggest if there is any other alternative way for saving a project information in to a custom field?

Thanks in advance..

Hi Srinivas,

You can use

CustomField.updateValue(FieldLayoutItem arg0, Issue issue, ModifiedValue arg2, IssueChangeHolder)

Because, issue.setCustomFieldValue()

Sets a custom field value on this Issue Object, but does not write it to the database.

You can use updateValue!!! It worked for me.

Appreciate if you could explain a bit more about the parameters for the updateValue method since i dnt have any references for them in my code.

The below code is working for me but i am getting problem only when updating project custom field.

resolver.createValue(issue, issue.getProjectObject().getLeadUser());

issue.setCustomFieldValue(resolver, issue.getProjectObject().getLeadUser());

Any other comments please?

Hi Spatruni,

You can use customFieldObject.updateValue() method to update the customField Value.

CustomField project = customFieldManager.getCustomFieldByName("Name of your custom Field");

project.updateValue(FieldLayoutItem arg0, Issue issue, ModifiedValue arg2, IssueChangeHolder issueChangeHolder)

Issue issue = issue object in which you want to update the value of customField.

ModifiedValue arg2 = new ModifiedValue(oldValue of customField, newValue which you want to update)

IssueChangeHolder issueChangeHolder = new DefaultIssueChangeHolder()

I think this will work for you.

It seems to want a generic value, not a Project object or Double. Have you tried setting it to project.getGenericValue() ?

srinivasp

I tried with GenericValue and found no exception this time but the value is not assigned. Any guess?

originalProduct.createValue(issue, componentManager.getProjectManager().getProjectObjByKey(pKey).getProjectCategory());

JamieA

Not sure originalProduct is - I think you want ModifiedValue as you had, but pass in a genericvalue for the new value.

srinivasp

getProjectCategory method returns GenericValue object and so i called that. Is that what you ask?

Renuka Patil

Hi Spatruni,

old value to modify you can take it as issue.getCustomFieldValue(customField)

new value would be a projectObject.getName().

I think this will work!!!

Renu

It wont work. because projectObject.getName() returns String but the new value requires reference of type ProjectCFType. I tested and posted the result on this thread long back.
