I've run into another issue implementing my signout function. When I compile, I
get the following error:
A link (Umdtalks/signout) could cause side effects; try implementing it with a
form instead
To address this, the manual says something about using an argument of type
Basis.postType. Is there an example of this somewhere?
I don't recommend using [postType] here. Instead, you want the normal
form support.
I would really like to keep this a link. Also, my signout function takes no
arguments so should it really make a difference whether the link is using POST
vs. GET variables?
Then you would be going against the HTTP standard semantics, which says
that GET requests may not cause side effects (and there is no way to use
POST from a link without some fancy JavaScriptin'). You could whitelist
the [signout] function for side-effecting GETs using the [safeGet] .urp
directives. Alternatively, this slight modification on Marc's suggested
code should also work:
<form>
<submit value="logout" action={signout}/>
</form>
P.S.: I'm changing the thread subject, which had become misleading. ;)
