Plugin conflicts with TYPO3 TypoScript Support by JetBrains
When both plugins are installed, you get this error message upon creating a new .ts file:
Cannot Create File
@NotNull method com/intellij/psi/impl/file/PsiDirectoryImpl.createFile must not return null
After deactivation of the JetBrains plugin, everything works fine.
Tested with PhpStorm 7.1.3
