We were using JSP EL expression to evaluate parameter value passed from a
custom tag to struts tag defined in that custom tag file. After we upgraded
Struts from 2.0.9 to 2.0.14, we had to modifed struts tag defined in our tag
file since JSP EL expression is allowed any more in struts tag because of
changes from WW-2107.
One problem is that, some OGNL expression parameter value can not be treated
as expression any more
when the paratemeters reach Struts tag. The value (such as "top") is always
treated as string literal "'top'"
in free marker therefore never been evaluated (returns "top" string as
result back).
Here is an example:
We pass "top" as listKey attribute value from customed tag defined in
select.tag.
If we don't check (if listkey=='top'), it would pass it as string literal
"'top'" to free marker
instead of "top" which get evaluated.
WAS:
<s:select name="${name}" label="%{getText('${label}')}" list="${list}"
listKey="${listKey}" listValue="${listValue}" headerValue="${headerValue}"
headerKey="${headerKey}" size="${size}"
emptyOption="${emptyOption}" tooltip="%{getTex….
NOW:
<c:if test="${list != null}"> <s:set name="list"
value="%{getList(#attr.list)}"/></c:if>
<s:select name="%{#attr.name}" label="%{getText(#attr.label)}"
list="%{#attr.list}" listKey="#attr.listKey
=='top'?top:getString(#attr.listKey)" listValue="getString(#attr.listValue)"
headerValue="%{#attr.headerValue}" headerKey="%{#attr.headerKey}"
size="%{size}" emptyOption="%{#attr.emptyOption}"
Thanks,
Qiang
