I did some tests with different kind and combinations of selector
"resource-exists".It seems I got a bug when using servlet:xxxx to get the
file from a different block.
What is working
==========
(sitemap from myBlock1 - the myBlock2 is a bean id):
<map:match pattern="filename.txt">
<map:select type="resource-exists">
<map:when test="resource/external/filename.txt">
<map:read src="resource/external/filename.txt"/>
</map:when>
<map:otherwise>
<map:read
src="servlet:myBlock2:/resource/external/filename.txt"/>
</map:otherwise>
</map:select>
</map:match>
and I can get the correct filename.txt.
What is *NOT* working
===============
(sitemap from myBlock1-the filename.txt exist at
resource/external/filename.txt - the myBlock2 is a bean id - myBlock3 id
does not exist or the file does not exists in myBlock3):
<map:match pattern="filename.txt">
<map:select type="resource-exists">
<map:when test="servlet:myBlock3:resource/external/filename.txt">
<map:read
src="servlet:myBlock3:resource/external/filename.txt"/>
</map:when>
<map:otherwise>
<map:read
src="servlet:myBlock2:/resource/external/filename.txt"/>
</map:otherwise>
</map:select>
</map:match>
Since myBlock3 does not exist, i am expecting that "test=" returns false and
map:otherwise is used. But unfortunately it _always_ returns true. It is
acting as if the "servlet:myBlock3:" part is completely ignored.
Maybe it is a syntax problem (found no documentation how it should look like
in 2.2), but i thought because of the working of the syntax inside map:read
it must be ok.
