style attribute not being rendered

I'm trying to add a style dynamically with HTL.

HTL code is:

<section class="header-page" data-sly-attribute.style="${header.cssStyle}" data-sly-use.header="com.acme.foo.Header"> </section>

And in my Java class I have:

public class Header extends WCMUsePojo { private String imagePath; @Override public void activate() throws Exception { ValueMap properties = getProperties(); this.imagePath = properties.get("fileReference", ""); } public String getCssStyle() { return imagePath.isEmpty() ? "" : String.format("background-image: url('%s')", imagePath); } }

But it's not being rendered, even when imagePath gets a valid value. I also tried using contexts, but nothing seems to be working.

Any ideas as what might be the problem?

Thanks

    Thanks PuzanovsP!

    Unfortunately it was my mistake when trying to put the code here, but in my code the method exists so the error is elsewhere. I edit my question to remove it since it's not really relevant.

    What I think is happening is that HTL thinks that putting background-image: url('/some/path') in the file can be harmful, I just don't know why. So my question is still open.

    Thanks for the suggestion on SlingModels it seems interesting.

    Hi Carloso,

    1) Create getter for cssClass variable, then, it will be shown.

    2) Consider using SlingModels, instead of WCMUse, it will promote cleaner code and better system in general.

    Regards,

    Peter
