When programming in Jelly, you can get in a situation as illustrated by the following code snippet:
Code Block |
---|
<JiraJelly xmlns:jira="jelly:com.atlassian.jira.jelly.JiraTagLib" xmlns:j="jelly:core"> <jira:CreateProjectRole name="QARole" description="QA role"> ${jelly.role.id} ${jelly.role.name} ${jelly.role.description} </jira:CreateProjectRole> <j:set var="qaroleid" value="${jelly.role.id}"/> <jira:AddPermission schemeId="0" permissions="Edit" type="projectrole" projectroleid= "${qaroleid}"/> </JiraJelly> |
The goal here is to create a new Project Role and then set the appropriate Permissions to it. However, as the projectroleid
and qaroleid
variables are have not the same type, you should get an error like this:
Code Block |
---|
Could not run script. Extra Information: [hide] Error: <JiraJelly xmlns:jira="jelly:com.atlassian.jira.jelly.JiraTagLib" xmlns:j="jelly:core">10010 QARole QA role Exception: org.apache.commons.jelly.JellyTagException: null:10:0: Cannot assign value of type 'java.lang.Long' to property 'projectroleid' of type 'java.lang.String' java.io.PrintWriter@334cee |
So qaroleid
, which received a java.lang.Long
value from the jelly.role.id
context variable, should be converted to a java.lang.String
type so it can be informed as projectroleid
attribute when setting a Permission.
How can you convert types in Jelly?
You can use the invoke
Jelly tag to call the method toString
on the jelly.role.id
context variable and store this value the in the qaroleid
variable. So you should replace this line...
Code Block |
---|
<j:set var="qaroleid" value="${jelly.role.id}"/> |
... with this...
Code Block |
---|
<j:invoke on="${jelly.role.id}" method="toString" var="qaroleid"/> |
... and the script will work sucessfully.
You can also (just as an example matter) use the new
Jelly tag to convert the java.lang.String
value of the qaroleid
variable into a java.lang.Float
value and store it in the qafloatvar
variable, as shown here:
Code Block |
---|
<j:invoke on="${jelly.role.id}" method="toString" var="qaroleid"/> <j:new var="qafloatvar" className="java.lang.Float"> <j:arg type="java.lang.String" value="${qaroleid}" /> </j:new> |
