Table: Entity getters assume strings, but there is no check

[joostdenijs]

Moved from private repository

One can use the Entity.setPRoperty method to set PartitionKey and RowKey properties to non-string values, but when trying to read them back via getRowKey or getPartitionKey, those methods will throw with something like "java.lang.ClassCastException: java.lang.Double cannot be cast to java.lang.String".

One approach would by to try to redesign the getters, but that seems wrong. The base problem is that those properties are special (must be set before submission, must be strings, must have EdmType null or "STRING", etc.)

The better approach would be to add validation when setting the properties with setProperty (check for the special properties) and setProperties (look through the map for the special properties). There is still a hole where one could directly add a property to the Map, but there is not much we can do there and it is more likely that people will add properties through the entity directly.
Regardless, there will still need to be pre-submission validation as well.

Here are the troublesome property getters, where no validation is done before getting the value:

• getPartitionKey
• getRowKey
• getTimestamp

fix would be breaking change, close.
