How to display all value of metadata from nodes collection model in content presenter template

Hi All,
first of all the new look of OTN is great.
coming to problem i am facing (i dont know whr to ask here or in portal forum).
i am creating a content presenter template to display list of items.
now as per requirement i need to create a drop down to filter the list.
now while check- in a file author would choose a value in one metadata field lets say xCategory(which is a single select list).
i have to display similar category list on portal to allow user to filter list.
i could hv used view of xCategory but problem is files are targeted to role using ACL. so u see i cant display all category to all users.
also customer wants this whole thing to be Dynamic i.e. they can add value of xCategory later that to could be only for specific role (on portal it should be role specific , author can see whole list not a problem there).
so what i think is if content is given as search result so the category. so now if i can get the all xCategory metedata from 'nodes' collection model in template i can create drop down with out having any additional bean.
somthing like this
#{nodes.xCategory} (but this one is not correct).
please suggest me any solution.
thanks

Hi,
you can do all of what you said with JSF. ADF Faces provides drag and drop functionality (have a look at the Web Developer Guide) that allow you to move nodes within a tree. The drag and drop framework sends an event notification to the server with a reference to the changed node.You can also have context menus on a tree node to help users creating, deleting and editing a tree nodes. JavaScript isn't required at all, even if you wanted to drag and drop a row in a table on top of a tree node to create a new tree node.
I just finished a book project in which we explained this usecase. As soon as I find the time, I'll follow up with a blog entry on this as it seems to be a common requirement. However, as mentioned, the web developer guide on OTN explains drag and drop in ADF Faces pretty well.
However, if you choose the "Search" link above, choose JDeveloper and ADF as the product to search for and type drag and drop as the search string, then you get lots of code sample posted in the past to this forum

How to display all the surveys using content query web part

Can you please tell me how to display all the surveys using content query web part in more details? I also created a subsite and multiple surveys in that site. Then, I inserted a Content Query Web Part and select the List Type to be "Survey",
however, it returned nothing. Did I miss anything?

Hi,
OOTB Survey List does not contain any
Content Types and it has the following structure:
Response entry is represented by
List Item
Response entry consist of questions and answers, where Question correspond to
Field and Answer to Item value respectively.
For querying Survey List via CQWP the following properties could be used
BaseType
<Lists BaseType="4">
ServerTemplate
<Lists ServerTemplate="102">
Example
To retrieve all the responses from Survey lists, specify List Type property as shown on picture
Reference:

How to show "ALL" Values by default in Page Drop-Down Lists in Pivot Tables

Hi Everyone,
Iam stuck with 1 problem please can any 1 help me if u know the solution.
Here is my problem:
How to show "ALL" Values by default in Page Drop-Down Lists in Oracle BI Pivot Tables?
For example, if you place Region in the pages area, a Region drop-down list allows the user to select a particular region, and see the data for only that region, rather than seeing all the Regions,But by default its not showing "ALL" option in the drop down list ,rather than doing that its showing result for only 1 region by default.
And an other problem with this pages area is, if we palce the multiple attributes in the Pages area in the pivot table, the (Fields)result is showing in vertically, the attributes 1 by 1(Every attribute in a new line) ,rather than showing like that, is there any way to show the results in horizantally?(We want to have it as a seperate drop drown list for every field horizantally not as a concatenated list).

Thanks Nikhil. But I am fetching the values from the LOVCache.java.
I am using <af:selectManyChoice>. Is there any way I can use LOVCache.java value for selecting default values instead of hard coding?
I mean to say can I write
unselectedLabel="#{LOVCache.entityTypeSelectionList.anyValue}"
where LOVCache.entityTypeSelectionList is used to populate the drop down box.

Interactive Report - How to display Aggregate values in first row

Hi,
I have an interactive report in which I have included aggregate for count.
But the count doesn't show until I navigate to the last page of the report.
Any idea how to display all the aggregate values on the top(in first row), so that the user doesn't have to click next to see these values.
Also when I downloaded the report the aggregate columns are not exported into csv. Any thoughts on this highly appreciated.
Thanks,
Raj.

Any help on this guys ?

It is looking like you are saving them as workbooks. It will be possible to maintain fliters if you save with the filters given by workbook properties, not by manual feeding.
let us know with clear expectation if you are not clear with it.

How to display negative values in a screen field of a screen

Hi All,
Please let me know how to display negative values in a screen field of a screen.
thanks

Hi Kishore,
You can do this method. In the screen , create a text field of CHAR instead fo creating an INT4 field.
I have created a field of CHAR of name say TEXT.
In the main program,
declare a variable of the same name ie. TEXT.
data: TEXT(5) TYPE C.
In PBO, just assign the negative values.
It will work.Since there is automatic conversion between character and integer data types, it will work for positive values as well.

Sylendra.
