Webform needs to flush Entity Cache after updating components (and e-mail configurations)

I've also been running into this. When a user adds a new component to the webform it won't appear until the cache has been cleared. I do receive the following warning when adding a component, though I don't know if it is related.

Notice: Trying to get property of non-object in node_page_title_pattern_alter() (line 39 of /sites/all/modules/contrib/page_title/modules/node.page_title.inc).

I did a little investigating and this problem is due to the Entity Cache module. This module is recommended for use with Display Suite, which is why I have it installed and this is likely the case for MrPhilbert as well. The easy fix is to simply disable the Entity Cache module and use Display Suite without it, but it would be nice for these modules to play nicely together.

I'm not too familiar with the Entity Cache module myself, but the following function call might be able to flush out the entity cache after a component creation.

entitycache_flush_caches()

3.9 has been working great for me, thanks for committing that patch. However, it looks like this is still an issue when adding a new recipient email. The email will be added to the system but won't actually show up until the cache is cleared. Disabling Entity Cache solves the problem so it seems this is directly related to this issue.

Thanks for all your hard work on this, I know it's kind of a pain to deal with module incompatibilities. We use Webform on nearly every site we build and I'm still amazed by how much it can do.

Oops, sorry about that. I'll make sure to open a separate issue next time.
