Hi All,

I'm having a strange issue where doing a .setValue on a ZEN datacombo is updating it with the value as-is, not the corresponding display value. Eg, if I connected it to query that returns two columns: ID,Name, and do a setValue(ID), I would expect the text in the datacombo to update showing Name. Instead it updates show ID, which I only want to use internally.

Hi! I have a complex SQL select query which I execute via %ResultSet. It also includes a UNION. The select statement within the union should only be done when an external parameter is set, and I'm not sure of way of doing that within SQL, other than something like


WHERE (some conditions)



WHERE :doUnion = 1 AND (some conditions)

...this works, but I don't think it's particularly optimal as I believe it will still execute the second SELECT regardless of :doUnion. It's also sort of hard to read...

$ZF(-100,..) issues

Hi, I found some issues with $ZF(-100) whilst replacing our old $ZF(-1) calls following the security alert. They're easy enough to work around, just figured it might be useful to someone :)

I'm trying to insert a relationship from a parent object instance to a child object instnace programmatically. Ie, i want to do:

Do parentObject.childRefProperty.Insert(chilDobject)

where childRefProperty is defined by a string. I feel this should be achievable with $PROPERTY and/or $METHOD or maybe something in $SYSTEM.OBJ.*, but can't quite figure it out. Anyone know?

Cheers :)

Hi all,

We're creating a series of RESTful APIs that output data from a Cache database (made up of global storage that we've mapped to classes). I'm running into some problems with object-to-JSON conversions when relationships are involved. Eg:

ParentClass has children relationship to ChildClass

ChildClass has parent relationship to ParentClass
