I’ve had this happen to me a few times lately, when using eForm with its tags in a chunk, and using a snippet in the form template. If I juggle cached/unchached snippet calls it will work, but if I don’t get it right the form template will simply display the snippet tags in place of the value the snippet should return.
I have a snippet that generates a dropdown select based on documents in a given folder:
<tr>
<th>Pages:</th>
<td>[[MakeSelect?folderID=`51`]]</td>
</tr>
The page containing the form is not cached, the eForm call is contained in a chunk and is called with [[...]] syntax. If I call the MakeSelect snippet uncached, then the snippet tags will be displayed. If I call the eForm snippet directly from the page, this doesn’t happen.
I’ve also gotten very odd displays of the snippet tags if I have spaces between the arguments both with eForm and with MaxiGallery, when called in a chunk. I say "odd" because both contain an &lang argument, and that argument gets turned into a <=`whatever`!
