After revising my code, I reduced the maximum OGNL expression length to 30,
since the longest expression remaining in my code is 28 characters.
<constant name="struts.ognl.expressionMaxLength" value="30" />
This, however, triggers another exception:
[ERROR] 2022-04-02 14:34:51 [https-jsse-nio-8443-exec-9] OgnlValueStack - Could
not evaluate this expression due to security constraints:
[#attr['s2b_form_element_class’]]
Evidently there are some automatically generated OGNL expressions with length
longer than 30. What’s a reasonable minimum expression length that will
accommodate these?
Thanks,
Ralph
