Introduction

Setting up a lookup field in Resco can be a challenging task, especially for those unfamiliar with the nuances of the JSBridge framework. If you've tried to dynamically set a view for a lookup field upon the change of another field and have encountered issues, you're not alone. In this post, we’ll go through a common pitfall and the correct way to implement a dynamic lookup view in Resco, providing you with a working solution to ease your development process.

The Issue

While attempting to set a view for a lookup field using JSBridge, a developer faced difficulties with their code. They were unsure about how to properly link the dynamic setup to the lookup field and what parameters to use in the method called to update the view.

Here’s a brief overview of their initial approach:

The confusion stemmed mainly from the first parameter, which represents the index of the lookup field on the form.

Solution

After some troubleshooting, a working version of the code emerged. The following code snippet demonstrates the correct way to set up the dynamic lookup view:

Key Corrections & Notes

Item Index: The crucial error in the original attempt was using an incorrect index for the lookup field. By replacing 0 with the correct index determined using detailView.getItemIndex("vWO.msdyn_substatus");, the code now dynamically updates the view correctly.

Dialog and Inline Setup: Ensure that you correctly create instances of LookupSetup for both inline and dialog displays.

Testing & Validation: After making adjustments, always test the setup within the Resco environment to confirm that the dynamic updates function as expected.

Conclusion

Dynamic setups for lookup fields in Resco using JSBridge can initially seem daunting, but with the correct implementation, developers can create robust forms that respond to user input in a streamlined manner. This post not only helps clarify how to set a lookup view dynamically but also highlights the importance of accurately specifying indices when calling methods.

If you’re working on configuring your own dynamic lookup fields, remember these insights and share this guide with others who may face similar challenges. Happy coding!
