The error may be due to constraints, but you'd have to show us the entire DSLR condition and its DSL definition.<br>

<div>Hi,</div>
<div> </div>
<div> I have been trying to add not exists constraint in dslr but its failing to parse the dslr. Here is what I am trying to do in DSLR</div>
<div><font size="2">
<p>[when][][<u>Tt</u>]here is at least one {entity}= not(exists {entity}: {entity}()) </p>
<p>If I simply use the exists constraint here then it works well. But then after adding not to it, its not getting parsed correctly.</p>
<p>error I am geeting is:</p><font color="#ff0000" size="2"><font color="#ff0000" size="2">
<p>[10,27]: [ERR 102] Line 10:27 mismatched input ',' expecting ')' in rule "Rule1" in pattern Person</p>
<p><font color="#000000">not sure whats going wrong here, if it is expected to work this way?</font></p>
<p><font color="#000000">thanks,</font></p>
