How to dynamically choose locale at SuperDevMode compile time?

[Davide Cavestro]

It seems that the super dev mode cannot benefit from the meta tag defined within a dynamic host page. I originally tried switching to the cookie solution, but now I guess the compilation triggered by the bookmarklet simply ignores any locale-related info derived from the host page, such as the meta property, the query param and the cookie (set on host page domain).

But this way - supposed the gwt locale should reflect some data coming from a database - we have no way to make the superdevmode aware of the chosen locale.

Moreover, Thomas Broyer recently suggested to

set the locale property to the full list of supported locales:
<set-property name="locale" value="en,fr" />

in order to achieve dynamic internationalization. I thought simply extending the locale property with additional values was enough, but I've found no documentation talking about multiple values for this property.

But as soon as I define multiple values for the locale property, the SuperDevMode starts compiling too many permutations, eventually complaining Multiple fragment 0 sourcemaps found. Too many permutations.

I guess this happens because it has no way to reduce the permutations based on the chosen locale (in fact it doesn't log any binding: locale=...).

So my question is: what should I do in order to dynamically choose the locale used by SDM compiler?

Hey guys, no idea at all? I would need a way to set the locale for the super dev mode compile (even from dedicated bookmarklets would be enough...)

I use meta tag in HTML for setting locale:
<meta name="gwt:property" content="locale=en" />

I use GWT from trunk, in Eclipse with -superDevMode argument, without bookmarklet. This patch works for me:
