[Simple-support] How to get an empty string, instead of null when reading @Text from element

[Alexander P. <ale...@er...>]

Hi

I have the following xml element:
<property name="my-prop"></property>

When I read it as in example below, the call to prop.getValue() returns null. How to change it to return empty string instead?

Sure, I can have a check in PropertyExample.getValue() method to check if the value is null then return ""; But was wondering if that is the recommended solution or if there is a better solution? Similar to @Text(empty="").

Rgards,
Alex
