Text viewer problem when using empty header

[Hitcher]

Currently if you don't want a header by leaving it empty but you previously ran textviewer that had a header value then the old value will be displayed.

PS The notes about escaping info need updating.

Noticed it aswell. And with Marcels implementation, too. It seems that this is an Kodi issue, because the label id="1" won't be cleared on unload.

What happens if this script sets it as empty if we don't supply a header value?

[sualfred]

My Pythons skills are very very very low but the script sets the header value even if no value is provided. That's why I think that this is a Kodi issue.

Thanks mate, hopefully Phil will be able to help.

Small workaround ;)

Haha, I was thinking of a similar fix but would rather not have to mess with the DialogTextViewer if it can be helped.
