'Linked issues' field data is lost while getting validation error message about 'summary'

[Ilia Shevelev]

Hi.

We experience 'Linked issues' field data loss while getting validation error messages like 'summary: You must specify a summary of the issue.'

How can we fix that?

Detailed description follows.

Sometimes I have to create issue which I know must be linked to certain previous issues.

So, I begin creating issue with filling 'Linked issues' fields group.

On this step (step #1) all is OK.

Than I go up and fill Desciption, Labels etc. 

But often forget to fill Summary field - in my case it's trivial.

So, on Create button jira says me 'You must specify a summary of the issue'.

np, I provide summary and my issue is saved.

But at this step I can find that all the data I've filled in 'Linked issues' field at step #1 is lost.

How can I fix that?

We use JIRA v6.1.4 with JIRA Agile v6.3.5 plugin.

The problem is reproduced only if I creating issue on the additional tab, e.g. pressing "Create issue" screen button with Ctrl or using link '/jira/secure/CreateIssue!default.jspa'
