Pedro Santos updated WICKET-6247:
---------------------------------
Summary: Property expression doesn't support '[', ']' and '.' characters
inside square brackets (was: Property expression don't support '[', ']' and
'.' characters inside square brackets)
> Property expression doesn't support '[', ']' and '.' characters inside square
> brackets

> Key: WICKET-6247
> URL: https://issues.apache.org/jira/browse/WICKET-6247
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 8.0.0-M1, 7.4.0, 6.24.0
> Reporter: Pedro Santos
> Assignee: Pedro Santos
>
> A property expression having a '[' character inside squar brackets like
> "bean.map[code[foo]" will fail because PropertyResolver replaces all '['
> charaters by '.['
> example:
> {code:title=PropertyResolverTest.java|borderStyle=solid}
> @Test
> public void shouldAllowMapKeysWithSpecialCharacters() throws Exception
> {
> String code = "[!@#$%^&*()_+-=[{}|]";
> String expression = "[" + code + "]";
> Map<String, Integer> integerMap = new HashMap<String,
> Integer>();
> PropertyResolver.setValue(expression, integerMap, AN_INTEGER,
> CONVERTER);
> assertThat(PropertyResolver.getValue(expression, integerMap),
> is(AN_INTEGER));
> assertThat(integerMap.get(code), is(AN_INTEGER));
> }
> {code}
> Plus a property expression having a ']' followed by a dot will fail because
> the dot will be taken as a token separator by PropertyResolver#getNextDotIndex
> {code:title=PropertyResolverTest.java|borderStyle=solid}
> @Test
> public void shouldAllowMapKeysWithADotAfterAClosingSquarBraket() throws
> Exception
> {
> String code = "].";
> String expression = "[" + code + "]";
> Map<String, Integer> integerMap = new HashMap<String,
> Integer>();
> PropertyResolver.setValue(expression, integerMap, AN_INTEGER,
> CONVERTER);
> assertThat(PropertyResolver.getValue(expression, integerMap),
> is(AN_INTEGER));
> assertThat(integerMap.get(code), is(AN_INTEGER));
> }
> {code}
> A possible solution is to use escape characters and there is a proposal to
> change the property expression syntax with such escape logic at:
> http://wicket-dev.markmail.org/thread/unwdqpxulw7tcd5l
> If we take the lack of support for valid index characters (a map key can
> contain '[', ']' and '.' characters) as a missing feature by design, we
> should update our wiki topic [1] to make it clear.
