Cannot read property 'get' of undefined. May i know if there are any trouble shooting points.

I have mentioned everything correct, but still i am facing the issue, may i know if there are any trouble shooting points.
Code:
Component:
<lightning:combobox name="Select Instance:" aura:id="selctOrg" placeholder="Select an Option" options="{! v.orgList }" value="{!v.selectedOrg }" onchange="{! c.handleChange }"/>
js controller:
var selectedSOrg = component.find("selctOrg").get("v.value");
Error is: [Cannot read property 'get' of undefined]
Below is the code that i had in my controller and helper.
controller:
({ doinit : function(component, event, helper) { helper.fetchSBHelper(component, event, helper); } })
Helper:
({ fetchSBHelper : function(component, event, helper) {
var sOrg = component.find("selctOrg"); var selectedSOrg = sOrg.get("v.value"); alert("selectedSOrg"+selectedSOrg);
} })

I want to execute process builder action only when the opporunity owner changed from A to B and using the advance option of specific changes made to  the record. i do not want to execute action for any other change of the record but it is giving me error. Any Suggestions?

Hi Developers,

Can anyone help me on this issue, I have a Child object that has a Lookup to Parent. I wrote the below apex class and the trigger on child, such that the count of Child records should be shown on each Parent record. I have a number field on the Parent which should be update as per the Trigger.

It works fine except in one scenario, it does not consider the existing Child records on the Parent, hence it shows incorrect count on the Parent record. It works perfect if I add the new Child records. I heard that Batch Apex can resolve this issue, I am not sure how Batch Apex is related here to resolve the isssue. Can I get some guidance here to proceed further.


Any help on this is much appreciated.
Thank you.

I'm having trouble getting an org chart google visualization working.  I don't have any problem getting the sample code working for orgcharts from http://code.google.com/apis/visualization/documentation/gallery/orgchart.html.

 

I'm also able to get the datachart working as per the example from http://wiki.developerforce.com/index.php/Google_Visualizations.

 

Then I created my own page with a datachart using a json dataset with the appropriate columns to support an org chart.  I displayed this json data on my visual force page with this code:

 

<c:DataTable jsondata="{!RelationTable}"/>

 

The chart displayed perfectly and the data appeared to be in exactly the format required for an orgchart.

 

Then I added this statement to display the data in orgchart format:

 <c:orgchart jsondata="{!RelationTable}"/>

However, this statement gives me the following error when I try to save the visual force page:

"Component c:orgchart does not exist"

 

Does anyone have any idea of why the orgchart is not considered a valid component?  Is there some other visual force code or script that can be used to display the orgchart?  I tried modifying the code from the documentation gallery example to use json data, but I was unable to get that to work.

 

Thanks for reading this and any help you might be able to offer.
