>             Project: Apache Airflow
>          Issue Type: Bug
>          Components: ui
>    Affects Versions: 1.10.3
>            Reporter: Marcus Levine
>            Assignee: Marcus Levine
>            Priority: Major
>             Fix For: 1.10.4

>
> After upgrading to 1.10.3, the task detail modal that normally appears when clicking on a task from the graph view does not appear when the DAG has not been run yet
> This makes it impossible to see the task details and rendered template prior to running the DAG
> In the JavaScript console, it appears this issue is caused by 'try_number' being undefined when the DAG has not been run yet:
> {code:java}
> Uncaught TypeError: Cannot read property 'try_number' of undefined
> at SVGGElement.<anonymous> (graph?dag_id=my-dag:1)
> at SVGGElement.__onclick (d3.v3.min.js:1)
> {code}
