[TYPO3-english] Bug in locallangXMLOverride mechanism since TYPO3 4.6?

[Lars Patrick Heß]

Hey all :-)

i am  using the "locallangXMLOverride" in TYPO3 4.6 mechanism to override XML-languagefiles, i use the following line oh php code to configure the override in a localconf-file:

	$GLOBALS['TYPO3_CONF_VARS']['SYS']['locallangXMLOverride']['path/to/originalTranslationFile.xml'][] = 'path/to/otherTranslationFile.xml'

The content of the original translation file "originalTranslationFile.xml" is this:

	<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
	<T3locallang>
		<data type="array">
			<languageKey index="default" type="array">
				<label index="test_label_one">one (default)</label>
				<label index="test_label_two">two (default)</label>
			</languageKey>
	
			<languageKey index="de" type="array">
				<label index="test_label_one">eins (german)</label>
				<label index="test_label_two">zwei (german)</label>
			</languageKey>
		</data>
	</T3locallang>


The content of the translation file  "otherTranslationFile.xml", which is used to override translations, is this:

	<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
	<T3locallang>
		<data type="array">
			<languageKey index="fr" type="array">
				<label index="test_label_one">une (française)</label>
			</languageKey>
		</data>
	</T3locallang>


My testcase in typoscriot is something like this, it only outputs two translations via the TS-TEXT object:
	config {
		linkVars = L
		sys_language_uid = 0
		language = en
		locale_all = en_EN.UTF-8
		htmlTag_langKey = en
	}
	
	# DE
	[globalVar=GP:L=1]
		config {
			sys_language_uid = 1
			language = de
			locale_all = de_DE.UTF-8
			htmlTag_langKey = de
		}
	[global]
	
	# FR
	[globalVar = GP:L = 2]
		config {
			sys_language_uid = 2
			language = fr
			locale_all = fr_FR.UTF-8
			htmlTag_langKey = fr
		}
	[global]
	
	page = PAGE
	page.typeNum = 0
	
	page.10 = TEXT
	page.10.data = LLL:path/to/originalTranslationFile.xml:test_label_one
	page.10.wrap = | <br />
	
	page.20 = TEXT
	page.20.data = LLL:path/to/originalTranslationFile.xml:test_label_two


The output in english (the default language) is this:
	une (française)  // << that's wrong! It must be "one (default)"
	two (default)

In german:
	une (française)  // << that's wrong! It must be "eins (german)"
	zwei (german)

In french:
	une (française)
	two (default) 


The error occured while processing the locallangXMLOverrides-files, while loading the language "default" from the translation file "otherTranslationFile.xml" (which does not contain any default-translations), the french-translations are rreturned! So the default translations from the "originalTranslationFile.xml" translation file will be overridden while the merging process!
When i replace the t3lib_div::readLLfile method with the code from TYPO3 4.5 (so that the new t3lib_l10n classes are not used) it works!

Does anyone knows the problem?

Thanks,
Lars
