Hi All,
I'm getting below error in accountList.html. Please guide me.


 

Hi All,
There are objects Vendor__c and Placement__c which are not related to each other. In component 1, I have two picklists "state" and "company".
On giving values to "state and company" and clicking "select" button, it should lists all the records matching state and company from object "Placement__c" in component 2.
Any help is appreciated.

Hi All,
There are objects Vendor__c and Placement__c which are not related to each other. In component 1, I have two picklists "state" and "company".
On giving values to "state and company" and clicking "select" button, it should lists all the records matching state and company from object "Placement__c" in component 2.
Any help is appreciated.
