groovy exception

[KKeerthi]

I'm trying check if a container is present or not in groovy script but it's throwing null pointer exception I'm handling that as below,

getPage(parent).recurse {
        page ->
            def content = page.node
        def property = content.get('sling:resourceType')
        if (property == "project/components/product-page") {
            count++;
            println page.path;
         def footercontainer =  getNode(page.path+"/jcr:content/root/container_1845659030");
         def refcontainer = getNode(page.path+refNode);
         if(getNode(page.path+footercontainer) != null){
                if(footercontainer.hasProperty(propName1)){
                (footercontainer).getProperty(propName1).remove();
             }
         }

Hi @KKeerthi 
You need to use node methods to check properties in the jcr node

 def property = content.getProperty('sling:resourceType').getString();

able to get pages with template but for some pages that container is not present, so there it's throwing nullpointer exception which I'm not able to handle through groovy.

in which line were you getting null pointer exception

Hi @KKeerthi 
The reason you are getting a null pointer exception is because you are passing the footercontainer variable to the getNode method, which is expecting a string path. Instead, you should pass the string path directly to the getNode method.

getPage(parent).recurse { page ->
def content = page.node
def property = content.get('sling:resourceType')
if (property == "project/components/product-page") {
count++
println page.path
def footercontainer = getNode(page.path+"/jcr:content/root/container_1845659030")
def refcontainer = getNode(page.path+refNode)
if (getNode(page.path+"/jcr:content/root/container_1845659030") != null) {
if (footercontainer.hasProperty(propName1)) {
footercontainer.getProperty(propName1).remove()
}
}
}
}

we pass the string path directly to the getNode method instead of passing the footercontainer variable. This should resolve the null pointer exception.
