Field data is not loaded before script run - require.js

Hi Experts,

We recently refactored the scripts of CRM 2016 and implemented the require.js. After this, we found inconsistency during function call on OnLoad of entity forms. We found that during OnLoad event sometimes controls were not filled with data though function was executed and it skipped the code if control is null.

So to overcome this issue we used setTimeOut function. However it works but we would like to know if any other way to get know that is the control filled or not, or any other way so that we execute our scripts for OnLoad event only after data loading for fields.

Any kind of help is welcome from all of you.

Hi Jaspreet,

normally, when you are in the OnLoad, it's safe to assume all controls have values - that's wha onLoad is for. Maybe you could post some code here so we could see how your Javascript looks like?

Hi Alex,

Thanks for your reply.

Actually we implemented require.js so we are not unig OnLoad event of form. We just calling the library of code in form properties and calling the function for OnLoad from webresource instead of OnLoad event of form.

Can you suggest something with this bit input?

I would advise against using requirejs like this because of the asynchronous loading nature - your entry point to your code must always be onload otherwise you cannot guarentee that the form is ready.

If you are using requirejs for your dependencies then you need to use something like webpack to bundle the files together and then reference as a webresource in the form - then call your logic from the onload

The biggest gotcha with requirejs AMD loafing is that Dynamics has no way of knowing your script dependances and so can’t cache or detect changes and make them available offline.

Hope this helps

Hi Jaspreet,

That's, likely, where the problem is. You cannot expect Xrm to be fully initialized until OnLoad happens, and it usually happens after the web resources have been loaded. Not sure what exactly you are doing, but I am pretty sure you just need to make it so that you don't try accessing Xrm before onload( just to be clear, I am talking about the OnLoad.event of the form, not about html onload)
