I was a bit disheartened to learn that the standard Grails GSP tag for ‘select’ didn’t accept a list in the ‘value’ parameter. This is necessary when building HTML SELECTs with multiple options preselected. So I wrote a patch, then realized it was already an issue, but hadn’t been looked at since May 07. I pestered the mailing list, and it might be looked at again for inclusion before the final 1.0 release (fingers crossed!).
This morning I realized that I could just make a new taglib. It’s not ideal, but what the heck, right? It gets me over my situation, and can make a slight mod to my code if/when Grails natively supports this functionality. In the meantime, I contibuted back my taglib. It’s mostly a pared down version of the stock FormTagLib.groovy file from Grails already, with non-select functionality removed, and my few extra lines added. The code is up here if you need this for your next Grails project.
