Using custom tags in template loaded from String via TemplateLoader fails

Reported by Erwan Loisant | October 5th, 2010 @ 11:58 AM

Using custom tags in template loaded from String:

    String code = "#{notification/}";
    Template templatePlay = TemplateLoader.load("myTemplate", code);
    renderTemplate(templatePlay.name, renderArgs);

generates error:

@6243j13i5 Internal Server Error (500) for request GET /entities

Java exception (In /app/controllers/Application.java around line 67)
NullPointerException occured : null

When i use render() method with the same code placed in HTML file everything works fine.
It could be nice to have good error reporting when working with template from String. By now it's just nullpointer Exception for most problems, without any description.

<h2>Play framework</h2>

<h2>Creating a bug report</h2> Bug reports are incredibly helpful, so take time to report bugs and request features in our ticket tracker. We’re always grateful for patches to Play’s code. Indeed, bug reports with attached patches will get fixed far quickly than those without any.<br><br>

Don't have too much expectations. Unless the bug is really a serious "everything is broken" thing, you're creating a ticket to start a discussion. Having a patch (or a branch on Github we can pull from) is better, but then again we'll only pull high quality branches that make sense to be in the core of Play.
