Issue wiTH $PAGE_SCOPE variables.

sandujamanuj

Hi,

I am trying to set the $PAGE_SCOPE variables and runtime using an external component. I ssue I am facing is these variables are not accessible in my layout XSL.

Env Details:

Sitepublisher : 7.2.1
OS : Linux.

Code:

I am using context.getPageScopeData().put(RuntimePage.PAGESCOPE_KEYWORDS, finalKeywordString); to set the keywords value in page scope and in layout XSL am using $PAGE_SCOPE[keywords] to fetch the values, but am getting null values.

Please suggest if someone has already faced the same issue.

External Component java class attached.

Hi

are you able to see the value in the log file which you set in java code?

Hey Shak,

Yes I am able to see the values in the log file.

I tried one more thing to see if there is some problem with my XSL.
I created a PreController and in the render method tried to access the Keyword variable value there but again got null values there also.

I was accessing the values using below syntax

WriteTxtLogger.log("Page Scope variables set :: " + context.getPageScopeData().get(RuntimePage.PAGESCOPE_KEYWORDS), "addPageKeywords");

Are you able to access the value in any of the components used on that layout? In the page, call your precontroller and access the $page_scope variable in one of the components. See if it works. I do have similar code in my env. and it works perfectly fine for components.

Hi,

Thanks for the suggession.
I will try that, but I need these values to be accessed in the XSL file.

Since these keywords and other meta data have to be added by the layout XSL on all the pages created.

One thing i realized that you are setting these values using an external component. Are you including this component in the page created using the same Layout or how exactly it is working?What is the actual sequence of events happening for this whole process of keyword setup and retrival?

sandujamanuj

Yes I am including the component on the page.
here are the sequence of events:

1. I created a component with and external. This external has the attached java class which sets the page scope variables.

2. I added the component on the page. To confirm if the external got executed I added a log statement which gets the page_scope variables. The log printed correctly.

3. Next I created a custom page type and in which I am accessing the PAGE_SCOPE variables using $PAGE_SCOPE[keywords].

4. Created a page using the same page type.

Am i missing something?

One more thing that I noticed. When I try to print the values $PAGE_SCOPE[keywords] in the component, it prints the values correctly and when I preview the page and see the head section using firebug Keywords are set.

But when I generate HTML out of it, I get null values.

Is it something to do with the ContextMode?

Do one thing, instead of having the component, create a precontroller with this code. Include this pre-controller in the site and then access the value in the layout. It should work.
It doesnt look right to me if you set the parameter value in one component and then use that value in other pages where the component is not even present.

I did try this thing but did not work for me either. Same result with blank values. Smiley Sad

One more thing thing that I tried. I added $CONTEXT{mode} in my component and tried to print the same on the component. When I add the component on the page $CONTEXT{mode} returns PREVIEW and it also prints the keyword page scope variable values. Whereas when I generate HTML from the page $CONTEXT{mode} returns GENERATE_HTML and the keyword values are blank.

Any idea how can we set the values for GENERATE mode. Eg: currently I am doing context.getPageScopeData().put(RuntimePage.PAGESCOPE_KEYWORDS, finalTitleString); to set the run time mode variables and somehow if I can do something like context.getPageScopeData().put(GeneratePage.PAGESCOPE_KEYWORDS, finalTitleString);

ok, i tried doing whatever i explained you earlier and i was able to access the values successfully in layout. i created a pre-controller and include that in a site. After that, modified the layout to use the variables from pre-controller and created a page in the same site. It worked without any issues.
How are you converting your attached class to pre-controller?

Hi Interdev,

ok, You are right. We can access the scope variable if they are set in the controller. I am also able to achieve the functionality.

Now I have a question here, I have .page and it has a component which allows the user to select a metadata DCR which has all the information. What I want is get that DCR path in my precontroller.

I can parse the .page using standard java XPATH Api but how do I get the full Vpath of the .page in my precontroller so that I can give that as input to the parsing method?

Few methods I tried:

context.getPage().toString() : Returns the content of the .page.

context.getPageLink(pagename) : Returns the absolute url for the HTML page generated from the .page like html/testsite/index.html.

context.getPageName() : Returns page name as index.

Any pointers?

Really appreciate your help and time.

Were you able to achieve this? i am facing the same problem now (not sure how it worked earlier) and not able to get the value of page_scope variables in generated html (even if i create a pre-controller)

contact support. it sounds like a possible bug in the generate html logic.
