Hello Ancheta,
You can achieve this using entity-condition tag, that is available at parallel
of view-link tag.
<view-link entity-alias="A" rel-entity-alias="B" rel-optional="true">
<key-map field-name="fk" />
</view-link>
<entity-condition>
<condition-expr entity-alias="A" field-name="fld" operator="equals"
value="FLD_TYPE" />
</entity-condition>
I have faced the similar problem earlier, but I was too busy to dig into this.
Code support is available for entity-condition under view-link, but it get
entity-condition null while fetching the childNodes of view link.
Once the above problem will fix you will able to get desired result by your
expression as well.
Thanks & Regards
