[Geoserver-devel] app-schema WMS sld filtering

Hi Niels,

I have been trying to debug an issue where if a filter imbedded in SLD such as the one below filters on a mapping where a function is used eg

Mapping:

if_then_else(isNull(HASRELATEDACTIVITY),toXLinkHref…

I get the error as show on the stacktrace attached. Would you be able to suggest where I should be looking? The exception is thrown from AttributeExpressionImpl.tryAccessor where the attPath(HASRELATEDACTIVITY) could not be found in the object. Any suggestions, tip or clue at this stage will be helpful thanks J

Hi Victor,

Unfortunately, functions throw this kind of exception whenever something goes wrong in the evaluation of an argument, this is kind of misleading but it has nothing to do with the data type. If the field /HASRELATEDACTIVITY/ does not even exist as a property in the object, an exception is thrown when trying to evaluate it. Normally it will return null but with app-schema mappings we did this on purpose by putting setLenient(true): see FilterFactoryImplReportInvalidProperty. The reason this was done is because people wanted an exception thrown if they accidentally misspelled the column name: see InvalidColumnTest.

Hope this helps.

Cheers
Niels
