Re: [development] hijack node submit/preview to process ajax call first?

[Aaron Winborn]

that's an interesting idea. i'll play with that, thanks adam! i need the ajax handling for the case of someone hitting the save button on the canvas itself (and would like to keep that for ui purposes), but i might be able to wing it using drupal's usual ahah handling.

Do you really need to send it via ajax to be processed and then submit the form? I know it creates a Huge post object but you're still dealing with the same thing if you are sending it via ajax just with an extra step. ----- Adam A.

Everything works, except that now I want to delay node submission until the canvas has a chance to save its work (assuming its associated 'Save' button hasn't yet been clicked). I'm mostly there, thanks to some help from merlinofchaos. Currently, I save the work and return false on the submit/preview click, and trigger('submit') after the ajax call to save the canvas. However, it's not quite working -- the canvas saves properly, storing the new fid in the field, but the form is reloaded, rather than processing. http://drupalbin.com/16680 Any ideas?
