#105 Template does not evaluate variables with first letter lowerCased and second upperCased

[phoenixcqcq]

I have fields in the model defined as:
private String name;
private String xQuery;
with getters:
public String getName()...
public String getXQuery()...

Freemarker is not able to evaluate xQuery by calling ${model.xQuery!"missing"}, but ${model.XQuery!"missing"} works.
When evaluating name, everything is OK: ${model.name!"missing"} works.
Why there is a need for the upper cased first letter when the second letter is also upper cased?

To put it simply, it's like that because the JavaBeans specification says so. As of the details, the root of the whole mess is that the camel case convention that Java uses is broken, as it requires you to keep the orignal case of the words, except that you convert the first letter to upper case. Like, you meant to write getHTML(), not the correct camel case form, getHtml(). Using your logic now we would have obj.hTML, which is of course even worse than obj.HTML. And so the JavaBeans specification says, that if you have consecutive upper cases letter, you can't lowercase the first letter.

Hi Daniel,
thanks for Your answer. You are right, XQuery should have first two letters upper cased. I gave wrong example. But imagine situation when the variable is called "iPhone". Using freemarkers ${model.iPhone!"missing"} it would print "missing". Or the getter would have to be getiPhone().

This matter is decided by the JavaBeans specification, not FreeMarker. Pretty much everything out there builds on that specification. You can provide a BeanInfo class though, where you can explicitly tell the name of the JavaBean properties.

OTOH, maybe FreeMarker should provide a way to deviate from the specification, like, accepting both obj.IPhone and obj.iPhone for getIPhone(), but that's then an RFE, not a bug.

Changed this to an RFE.

There are some other tickets that have problems with java.beans.Introspector, so maybe we should push our own implementation as an option: https://sourceforge.net/p/freemarker/feature-requests/92/, https://sourceforge.net/p/freemarker/feature-requests/94/
