Hi All,
When I use call mediator in my sequence as below it gives error [1].
<call blocking="true">
<endpoint *key-expression*="$ctx:SAMPLE_ENDPOINT"/>
</call>
If I change the code as any of below, its works fine.
<call>
<endpoint *key-expression*="$ctx:SAMPLE_ENDPOINT"/>
</call>
<call blocking="true">
<endpoint *key="*gov:/testEndpoint*"*/>
</call>
Do we have a problem in Call mediator with the combination of *blocking=true
*and *key-expression *in endpoint ?
