Sibling bindings

[Gabriel Piacenti]

I'm trying to write something using the OOPath notation and I'm having some problems dealing with sibling bindings

I want to do something like this

/a[$aBinding:this, /b[some conditions, $bBinding: this], /c[some conditions, $cBinding: this]

Since the data is hierarchical I can't really separate these very well but the b and c bindings share the same parent. The main problem is that an OOPath like the above ends up in an error like "Only one oopath per pattern is allowed".

I am using the latest version of Drools (10)

Is there some syntax issue or limitation I'm hitting here?

[Alex Porcelli]

Can you share a more concrete example?

You are missing one "]" here.

You should be able to write something like this if that helps:

$aBinding: /a

$bBinding: /b[some conditions]

$cBinding: /c[some conditions]

Note there are no commas at the end of the lines.

I can do the following but it does seem a bit wasteful
/a[$aBinding:this]/b[some conditions, $bBinding: this]

/a[this==$abinding]/c[some conditions, $cBinding: this]

If there is no branching that can be done for binding in a single path, at least this can do it by making sure it is operating off of the same parent

yeah, sorry that was a mistake when copying over but I had the proper closing brackets, non trailing commas when I tried to run things. 

An analogous use case could be that I have a list of locations, each with a list of builds in them as well as other data such as a list of street lights, or fire hydrants. So basically I would like a binding to the location and bindings to specific street lights or hydrants under that location. So those just happen to be sibling lists of objects and from what I tried out it doesn't seem possible to bind to these items in a single path but may rather require multiple paths like I did in my workaround solution I posted.
