> The RewriteFilter is non-deterministic in some cases. An example serves best.
> Here are the rewrite rules I would like:
> /Customer/edit/{id}	-> /jsf/Customer/Edit.xhtml
> /Customer/create	-> /jsf/Customer/Edit.xhtml
> /Customer/{id}		-> /jsf/Customer/View.xhtml
> When debugging the value of RewriteFilter.getAllPatterns(), the order of the two rules for /jsf/Customer/Edit.xhtml are always preserved.
> However, because Pages.getKnownViewIds() returns a HashSet there is no guarantee that the rules for /jsf/Customer/View.xhtml will come after the rules for /jsf/Customer/Edit.xhtml.  As a result, /Customer/create sometimes translates to /jsf/Customer/View.xhtml when /jsf/Customer/View.xhtml is returned first in the set.
> There are several possible solutions:
> 1) Change /Customer/{id} to /Customer/view/{id}. However, this is not the best url for a View.
> 2) Change Pages.pagesByViewId to a TreeMap. This is the patch I am currently using, but it is only guaranteed for my patterns.
> 3) Change RewriteFilter.getAllPatterns() to returns a TreeSet sorted from longest to shortest. This is similar to the way Pages.wildcardViewIds works.
