I am trying a HTL/Sling Model example with HTL Parameters and Sling Model Injection. However, the parameters passed via HTL are always null. Does anyone have a solution?
Java --> Inject example: com.testing.models.SimpleHelloWorld
@Model(adaptables = Resource.class)
public class SimpleHelloWorldModel {
@SlingObject
private Resource currentResource;
@SlingObject
private ResourceResolver resourceResolver;
@Inject
@Optional
protected String testProp;
private String localProp = "test value";
@PostConstruct
protected void init() {
this.localProp = testProp;
}
public String getTestProp() {return testProp;}
public String getLocalProp() {return this.localProp;}
}
The idea is to receive a value from HTL (testProp), see if the init() method gets correctly invoked due to the @PostConstruct annotation and set a local property.
Here is the very simple HTL snippet:
<sly data-sly-use.hw="${ 'com.testing.models.SimpleHelloWorldModel' @ testProp='from HTL' }" />
<div class="add-message">
<h3> class="we-ProductsGrid-item-title h4">Testing HTL/Sling Model</h3>
<h3>Testprop: ${hw.testProp}</h3>
<h3>LocalProp: ${hw.localProp}</h3>
</div>
The init() method gets invoked.
However, every property I pass via HTL is null. The @Deleted Account annotation sets blank.
Does anyone know if HTL has been updated to pass parameters to a Sling Model Class that can be read via @inject?
Solved! Go to Solution.

Please update your annotation to below and try:
@Model(adaptables = {Resource.class, SlingHttpServletRequest.class})
