Hi All,
I have created a component which has a list value being returned from Java. Everytime I author the component the value obtained in the html is null. In the logs it gives a null pointer exception. The values in these fields are coming from tagging in AEM. How do I place a null check condition in the component? PFB the snippet of the code in sightly :
<div data-sly-list.collist="${column.getcolumnList}" data-sly-unwrap>
<div class="pr-0 pl-0 outer-container ${properties.padding} ${collist.getparentClass}" style="" >
<div class="inner-container ${collist.getchildClass} ${collist.getCorners}" style=";border-color:${collist.getBordercolor !=null ? collist.getBordercolor : '' @ context = 'unsafe'}">
<div data-sly-resource="${ @path=collist.getNumber, resourceType='foundation/components/parsys'}">
</div>
</div></div>
Note: I have to add the condition for ${collist.getparentClass} and ${collist.getchildClass}
Solved! Go to Solution.

Hi,
The issue could be, how you are calling methods in sightly. If Java methods have names start with get then no need to use get in sightly.
e.g. Java method - getList() then sightly it should be call like obj.list
and make sure you define method name with proper camel case.
instead of ${collist.getparentClass} use ${collist.parentClass}
