Hi All,
Not sure if this is the right forum for this query. If not, please point me to one or redirect my query to that audience.

Since last week, I am unable to access the below link to Architecture center on developer.salesforce.com. I am getting 404 Not found Error.

If its moved, what is the new link?

Thanks and Regards,

Before lightning, mapping of an Article Type to Data Category was possible using an interface (Article Management) that allowed to store that mapping in "Article Type__DataCategorySelection. 

In Lightning Knowledge, Article types are gone and we got record types. Given that, how do we map an Article to a Data Category defined in Data Category setup? Is there any other field that is given for the mapping? I do not see any such field in definition of "Knowlege Object" in Setup.

Found a related post that mentions creating a custom field on Article/Record Type.

Using it i can make a Picklist of values having same text as that in data Categories. However, the values will not map to the DataCategory definitions in "Data Category Setup" of Lightning KB.

Without it, I am NOT able to assign my Articles(in Lightning KB) to Data Category. Without this assignment, those Articles are unable to be mapped to the Topics defined in Community Site. Has Salesforce removed this very critical mapping!! ??

Hi Lightning Experts,

For Contact/Case objects, in OOTB Lightning  Record Details Page,  I need to limit field "Description" [OOTB (Standard field )] to only 5000 characters. Being a LongTextArea type, it allows 32000 characters as default behaviour.

Using Validation Rule I can do it. However the issue is, I want the UX to stop user typing 5001 th character.  Not that a rule flags error ONLY while trying to save entire page changes. As there might  be 2-3  more such fields with same behavioural requirement.

Also aware that being Lightning, any JQuery/ JS is discouraged due to clash with Locker Service.  So, any thoughts how to achieve it? With or without JQuery?

Hi,

In my DE, I finished Hands-on challenge for "Getting started with Apex" module.  As instrucuted in Trailhead, i launched my DE from drop down next to "Launch your hands on Org".

However, on clicking "Check Challenge" button in TrailHead i get below error.

Challenge Not yet complete... here's what's wrong: 
Executing the 'generateStringArray' method failed. Either the method does not exist, is not static, or does not return the proper number of strings.

Please guide, how to fix this as i successfully executed challenge by successfully calling my Apex class ("StringArrayTest") in "Exeucte Anonymous window".

Thanks & Regards,
