JSP: Escaping Expression Language (EL)

[DRS.Usenet]

A strange thing happened to on of my apps.

I have this:
<INPUT type="CHECKBOX" name="directory"
value="${piFolder.category}\${piFolder.group}">

I published to one server at one point in time and it the value came
back where both EL expressions were evaluated (for instance
"mycategory\mygroup").

I published to a different server and the value came back for only the
first EL expression (for instance "mycategory${piFolder.group)").

So, it appears that the backslash is being treated as escape character
for EL?

Any ideas for scriptless workarounds?

You could do this:

${firstExpression}${ '\\' }${secondExpression}
