Trying to create an Apex trigger that updates the Opportunity splits to evenly distribute the percentage of the sale to each Opportunity Team Member. I'm using a split that validates to 100%, and I'm getting this error every time, even though it adds up to 100%.

I was getting an error with the trigger, so I looked up the split records (2 team member, 35% and 65%) that I created manually on the opportunity with a SOQL Query.  I tried editing the individual split records to 100 and 0 percent. I get the following error when I click Save Rows. This was the same error I was getting in my trigger.



​​​​​​​Thanks for your help!

Hi,

I'm trying to get an sObject list that I'm creating in my Apex controller to output on a VisualForce page, but nothing is appearing on my VisualForce page. Can you help? :)

Also, I can see debug logs for my Visualforce page, but not for the Apex controller. Is it possible to view Apex controller debug logs?

Thanks for your help!

Hi,
Just wondering, how this "{!(contactList.size != 0)}" syntax is working. I knew List.size() is always used. in this example '()' is missing. Any idea??

EXAMPLE:
<apex:pageBlockTable value="{!innerContactList}" var="innerCont" <strong><font color="#ff0000">rendered="{!(contactList.size != 0)}"</font></strong>>

Thanks.
