| I'm trying to hide some text if an array is empty, so I tried this :
<wo:WOConditional condition = "$member.organizationProfiles.isEmpty">
But I'm getting :
<org.wocommunity.logic.eof.OrganizationProfile 0x40964823> valueForKey(): lookup of unknown key: 'isEmpty'. This class does not have an instance variable of the name isEmpty or _isEmpty, nor a method of the name isEmpty, _isEmpty, getIsEmpty, or _getIsEmpty
Why it's trying to find isEmpty on a OrganizationProfile instead of the array (which is populated with OrganizationProfile objects)? So far, the only way I found to check if it's empty with non-Java code was with :
OrgsProCondition : WOConditional { condition = member.organizationsProfiles.@count > 0; negate = true; }
I also tried with :
<wo:WOConditional condition = "$member.organizationProfiles.@count > 0">
But I get a "has a quote left open", and using > didn't help.
