Not long ago, I wrote a post about the need of a free service that provided a variety of information related to currencies who led me to Open Exchange Rates: Real-time exchange rates for developers!
At that time I also mentioned how I had a couple of projects in mind related with the library I wrote then, curiously, one of these projects also matched a need felt by others: improving/automating the way how exchange rate updates are made in SugarCRM projects.
Two months later, more or less, I’m back with news regarding these projects: a few minutes ago I’ve released publicly, and more important, freely, my two first SugarCRM packages.
When it comes to labels, by default, this function only loads current module labels into SUGAR.language.
What you need to do is inject some logic to clear selected field values before the view is displayed.
Like all other stuff made in SugarCRM, this process also depends on what type of module you’re hacking, in other words, the place where you’re going to write the logic depends if you’re hacking a custom module or a core one.
