Checking property existence of include fragment

[Raúl Sánchez]

Hi all,

Is there some way to check if a property in include fragment has been set?

Example:

<include refid="myFilterLocation">
      <property name="model" value="model_name"/>
...
...
...
</include>

And then when this fragment is used:

<if test="....">
AND ${model}= #{${param}.model,jdbcType=VARCHAR}
</if>

Is there some way to test if the property is not sent. I want not send properties if I do not want to filter in my query.

Kind regards.
