Hi!
We are currently migrating a web app from 5.5.20 to 6.0.26 (with identical
behaviors on different operating systems). On a few pages, we are experiencing
a different behavior related to EL expressions.
In the example page below and with tomcat 5.5.20, the expression in the line
<html:link href="#${currentBlockName}"
was correctly evaluated. With tomcat 6.0.26, it is not evaluated, resulting in
links that directly contain the literals #${currentBlockName}.
I know that in EL 2.1, ${} (immediate evaluation) and #{} (deferred evaluaton)
are two possible types of eval expressions, but why is the combination of #${ a
problem if it occurs in a tag attribute?
Other expressions are evaluated without problems, so with have no general
problem with them (no general deactivation of EL or something like that). It is
always the combination of #${ in tag attributes.
Can somebody help?
Best regards,
Oliver
