[opencms-dev] accessing navInfo or some other property

[Pavel Peringer]

Hello

I suppose that you need this property on request file - URL. Else you 
need to use methods wih parameter(path-to-resource).
You have two ways:
1) Use CmsJspNavBuilder

CmsJspActionElement cmsJsp = new CmsJspActionElement(pageContext, request, response);
CmsJspNavBuilder cmsNavigation = cmsJsp.getNavigation();
CmsJspNavElement element = cmsNavigation.getNavigationForResource();
String navInfo = element.getInfo();

2) Direct read property with CmsObject

CmsJspActionElement cmsJsp = new CmsJspActionElement(pageContext, request, response);
CmsObject cmsObject = cmsJsp.getCmsObject();
CmsRequestContext cmsRequest = cmsJsp.getRequestContext();
String requestFile = cmsRequest.getUri();

CmsResource resource = cmsObject.readResource(requestFile);
String navInfo = cmsObject.readPropertyObject(resource, CmsPropertyDefiniton.PROPERTY_NAVINFO, false).getValue();

I use the second way, because when you read "standard" property 
"NavText" and the value is not set on resource, you get to HTML code 
OpenCms warning message "+++ File property "{0}" on "{1}" not found. 
+++" and " ends string in attribute and HTML is not valid. With second 
way you get null or value and output is up to you.

Using readPropertyObject with CmsResource instead of String resourcePath 
is DB load optimalization. When you read property with String path, 
OpenCms first reads CmsResource and then calls readPropertyObject with 
this CmsResource. So you should use readResource and then 
readPropertyObject in case you need to read more than one property on 
same resource.
