Lukasz Lenart commented on WW-4870:
-----------------------------------
The case here is that there two layers which perform conversion. First
Freemarker tries to convert a String to a number (because the String looks like
a number - see the whole discussion here WW-4837 and this [1]) and probably it
uses a default locale ({{fr}}) and now it passes the BigDecimal to the Struts
tag. So now Struts/OGNL tries to convert the BigDecimal back to the String (an
expected type) and it uses defined user locale ({{fr}}) to convert a BigDecimal
to a String.
Using quotes as suggested by Yasser could help.

>
> Hi Apache / Struts 2 team,
> We've just discovered a bug with the new version 2.5.13 of Struts 2, mainly
> in OGNL dependency. This is not the case with 2.5.10.
> *Scenario*: we have a boolean method in a "if" condition statement in FTL
> view. This method takes on argument which is a String ID in the format "X.Y"
> (ex: "1.1).
> *Result obtained during the OGNL parsing*: StringConverter is called
> according to the "locale" of the browser and apparently with "fr_FR" locale,
> the "X.Y" is converted to decimal format "X,Y" which is wrong since we want
> to stick with our ID as it arrives.
> It seems with en_US locale, the decimal conversion doesn't happen.
> *Result expected*: the ID "X.Y" goes to the "if" statement as it is, not
> converted in fr_Fr locale.
