Here are highlights from article Salesforce CLI Open AI Plug-in – Generating Records
1. Passing Parameters to Apex Method from Visualforce Page
– Developers often wonder how to pass parameters to a controller method in Visualforce.
– Parameters can be passed using action methods, command buttons, and action support tags.
– The parameters can be passed through URL parameters, JavaScript remoting, and JavaScript methods.
– The parameters can be accessed in the controller method using the “apex:param” tag or by directly referencing the parameter name.
– It is important to properly handle null values and data types when passing parameters.
2. VisualForce Lookup
– Adding an input field with a lookup or master detail field in Visualforce allows users to enter a text string.
– The lookup or master detail field renders a field for selecting a related record from a lookup or master-detail relationship.
– The entered text string is used for searching and selecting the related record.
– The selected record can be stored in a variable in the controller for further processing.
– It is important to handle errors and validation when working with lookup fields.
3. Visualforce Re-rendering Woes
– Re-rendering in Visualforce allows partial page updates without refreshing the entire page.
– It can be challenging to handle re-rendering correctly, especially when dealing with conditional rendering.
– Errors can occur when re-rendering components that have not been rendered or when re-rendering components that have already been rendered.
– It is important to properly structure the Visualforce page and controller logic to avoid re-rendering issues.
– Using apex:outputPanel and apex:actionRegion tags can help in controlling the re-rendering behavior.
