New Locale aware conversion logic
As from Struts 2.5.12 a new conversion logic was introduced which can affect your applications when using uncommon solutions. One of these is to use
a number literals in Freemarker template. In such case Freemarker treats them as numbers (as
BigDecimals) and Struts logic converts them to a string with decimal zero, see the example below:
<@s.textfield name="userId" value=35/>
this snippet will produce the following Html control:
<input type="text" name="userId" value="35.0"/>
To resolves this problem you must add quotes around the value:
<@s.textfield name="userId" value="35"/>
This is due how Freemarker treats a number literals.
