I've got a page that uses s:optiontransferselect, and I'm pretty happy
with it, but I'm now trying to scale up this app, and just over 1000
entries and the freemarker template bombs out:
FreeMarker template error!
Error on line 264, column 13 in template/simple/optiontransferselect.ftl
stack.findString(parameters.doubleListValue) is undefined.
It cannot be assigned to doubleItemValue
The problematic instruction:
----------
==> assignment:
doubleItemValue=stack.findString(parameters.doubleListValue) [on line
264, column 13 in template/simple/optiontransferselect.ftl]
in user-directive s.iterator [on line 256, column 9 in
template/simple/optiontransferselect.ftl]
in include
"/${parameters.templateDir}/simple/optiontransferselect.ftl" [on line
24, column 1 in template/xhtml/optiontransferselect.ftl]
----------
Java backtrace for programmers:
----------
freemarker.core.InvalidReferenceException: Error on line 264, column 13
in template/simple/optiontransferselect.ftl
stack.findString(parameters.doubleListValue) is undefined.
It cannot be assigned to doubleItemValue
The actual number is confusing: It works with 1125 total in list2 (with
2 selected and instead in list1), but with 1126 possible values it
crashes. Usually the size at which something breaks is indicative, but
the only thing I can think of is 1126 -2 (selected) = 1024 + 100 ?
Clearly I need a different solution here, but this is a really bad
failure mode, as that error cascades into sitemesh crashing, and results
in no page at all. If this tool has a limit, I think it would be better
to drop entries beyond the limit and still result in a functional page.
Opinions? Any ideas where this limit comes from? Quick searches for
freemarker limits found nothing...
