We have a navigation (tree widget) that is generated with JavaScript. Clicking on the tree nodes is supposed to load an url i the content iframe.

A hidden form is used for this. By clicking on a tree node a hidden inputs field value is set and the hidden form is submitted that does a post to the iframe (using target on the form).

First question would be if this is the best solution for this. Feels a bit hacky.

But the main problem is that the form is only submitted every other time.
