i'm pretty new to silverstripe, i'm currently working on trying to migrate a few items from an existing website i've built from scratch. so far, i've had good success, the stuff i'm migrating is all php based with a mysql backend for data storage in some cases. i'm having trouble with one item, dynamically generated graphs that use jpgraph (jpgraph.net).
i've got a very simple example in place now, when i browse to the page, i get the following error:
Fatal error: Call to undefined method HTMLText::setValue() in /var/www/localhost/htdocs/sapphire/core/ViewableData.php on line 380
i've isolated the issue to jpgraph's include files, if i add them to my new php file for use with silverstripe, i get the error. otherwise silverstripe works fine, minus the graphs, of course.
is there a way to work around this error?
