modify the field shown in the title of an issue?

[Manuel Villegas]

it is possible to modify the field shown in the title of an issue ?

Currently the field resume is shown in the title and I would like the name field to be shown

That field ("resumen") is the summary of the issue.  If you want different data in it, you will need to put your data into the summary field.

If you just want to move the fields around the screen, rather than change the data, you will need to re-write the code that renders the issue view (which I can't recommend)
