Hideshow region column sort problem

Hi,
I have a HideShow region containing a PPR report. All is well except that the region hides when I click a column header to sort.
Anyone got a solution to this?
I've tried a few methods involving trying to store the ID of the region in a user-preference, but so far no joy.
Seems the kind of thing we need a generic method for.
Many thanks,
John D

carl,
Thanks for the quick response.
Glad to hear that it's a fairly easy fix, but sad to say I don't know how to implement it. Could I ask you to be more explicit?
I will be too. The problem affects any hideshow region with sortable columns, so I'm looking ideally for a generic fix.
The specific case in point is a page with 3 reports, each in a hideshow region and each in a ppr report template (though the ppr bit is irrelevant - happens with standard templates too, as it would).
The column headers generate HTML such as:
HREF="f?p=100:625:1253185985800118:fsp_sort_2::RP&fsp_region_id=2004914903282889">FirstName<(I left out the <A... A> to aid legibility here)
So I guess (yep, guess) what's required is something like:
- on an fsp_sort request, somehow trap and store the ID of the given region;
- either in the page onload code, or maybe in the page footer, fire the onclick method for the toggle element for the given region, as you suggest.
Unfortunately this is currently beyond me. Any further help will be much appreciated.
Thanks
john

ADF Faces: columns sort problem

Hi all,
I'm new ADF Faces italian user and I have some problem sorting columns of table component...
I have tried to convert my ResultSet in a List, and the data are correctly inserted in the "af:table" but the column sort don't work...
I have already read the "af:table" Oracle specification but I have not just found a solution...
This is the part of my backing bean that return the List:
private List anagsList;
public List getAnagsList()
Connection connection;
Statement statement;
ResultSet resultset;
try
Class.forName("oracle.jdbc.driver.OracleDriver");
connection = DriverManager.getConnection("jdbc:oracle:thin:@192.168.168.75:1521:ORA1", "EL2DEMO", "admin");
statement = connection.createStatement();
if(inputText1.getValue().toString().equals(""))
resultset = statement.executeQuery("SELECT AN_RAGSOC, AN_NOME, AN_DATANASCITA FROM ANAGS");
else
String query="SELECT AN_RAGSOC, AN_NOME, AN_DATANASCITA FROM ANAGS WHERE ";
query=query + "AN_RAGSOC LIKE '%" + inputText1.getValue() + "%' OR ";
query=query + "AN_NOME LIKE '%" + inputText1.getValue() + "%' OR ";
query=query + "AN_DATANASCITA LIKE '%" + inputText1.getValue() + "%'";
resultset=statement.executeQuery(query);
anagsList = new ArrayList();
while(resultset.next())
anagsList.add(new AnagsRecord(resultset.getString(2), resultset.getString(1), resultset.getString(3)));
resultset.close();
statement.close();
connection.close();
catch(Exception e)
System.out.println(e);
return anagsList;
This is my AnagsRecord class:
package mypackage.backing;
public class AnagsRecord
private String nome;
private String cognome;
private String dataNascita;
public AnagsRecord(String nome, String cognome, String dataNascita)
setNome(nome);
setCognome(cognome);
setDataNascita(dataNascita);
public String getNome()
return nome;
public void setNome(String nome)
this.nome = nome;
public String getCognome()
return cognome;
public void setCognome(String cognome)
this.cognome = cognome;
public String getDataNascita()
return dataNascita;
public void setDataNascita(String dataNascita)
this.dataNascita = dataNascita;
And this is table component:
<af:table var="al" emptyText="No records found."
rows="20" value="#{backing_ADFFaces.anagsList}"
banding="row" bandingInterval="1">
<af:column sortable="true" sortProperty="dataNascita">
<f:facet name="header">
<af:outputText value="DATA NASCITA"/>
</f:facet>
<af:outputText value="#{al.dataNascita}"/>
</af:column>
<af:column sortable="true" sortProperty="cognome">
<f:facet name="header">
<af:outputText value="COGNOME"/>
</f:facet>
<af:outputText value="#{al.cognome}"/>
</af:column>
<af:column sortable="true" sortProperty="nome">
<f:facet name="header">
<af:outputText value="NOME"/>
</f:facet>
<af:outputText value="#{al.nome}"/>
</af:column>
</af:table>
I have already installed the ADF Faces demos (column_sortable.jspx) and it works well, but the backing bean is not very understandable...
please help me...
ciao!

Report Column Sorting problem

I have a report based on a view. For some reason some of the columns are not being sorted correctly. After pressing the column header to sort date columns the underlying data is not sorted properly (its out of order) or its not sorted at all.
Can you please let me know if there is a known bug causing that?

I think I'm having the same problem.
I have a report with data columns, several "not shown" columns, and several column links. I've noticed that any columns in the query after a certain point, will not sort the correct column. If I show all the columns and allow them all to sort, then some of the columns will sort the data in another column. (for example clicking on the header/sort link for column x sorts the table by column y and clicking on the sort link for column z sorts column x, etc).
I've noticed that I can move columns around in my select query and no matter how they are arranged, after the 7th or 8th column in the select statement, none of the columns following that will sort properly. I've tried all kinds of things, changing my select query around, enabling and disabling sorting, adding additional null columns in, setting and unsetting the default sort order, changing the order of the columns in the report. I don't have an order by in my query or anything weird besides some where clauses (most of which are from the default search functionality).
Has anyone found a solution to this problem? We just upgraded from HTML DB 2.2 to APEX 3.0 and the problem remained the same.
Thanks,
Greg

Column sorting problem

The fields which represent prices are not sorted logically at
all, whether I set the column type to "number" or not. If the price
list contains values {90, 60.5, 42.5, 400}, sorted ascending gives
{90, 60.5, 42.5, 400} and descending {400, 42.5, 60.5, 90}??? And
how can I achieve to have two decimal numbers even if the number is
whole like 90 => 90.00 or 60.5 => 60.50. Setting the colum
type to "number" I lose these decimal numbers.

If I have the following code:
// data set
<script type="text/javascript">

</script>
//html markup
<div spry:region="ds1">
<table>
<tr>
<th spry:sort="value">Value</th>
</tr>
<tr spry:repeat="ds1">
<td>{value}</td>
</tr>
</table>
</div>
The xml file is:
<?xml version="1.0" encoding="iso-8859-1"?>
<employees xmlns="
http://www.foo.com/employees">
<employee id="123543">
<value>90</value>
</employee>
<employee id="127944">
<value>60.5</value>
</employee>
<employee id="127373">
<value>400</value>
</employee>
<employee id="127373">
<value>42.5</value>
</employee>
</employees>
Please check with you page what's wrong, because with the
code that I gave you above it works.

Report region columns constrained to 4000 chars? Hitting LOV problems.

Hi all,
I've hit a problem that I'm hoping will have a simple answer.
Quick overview of issue:
APEX 3.01 application running against a 10gR2 DB.
We have an LOV defined that works just fine on various forms but in report regions where the LOV is available via a drop down column value in the report region HTML table we are hitting the error:
report error:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
Some judicious debugging reveals that this seems to be because we are trying to load in more than 4000 characters into the LOV drop down in the report regions HTML table column (it's a moderately large LOV)..
This suggests that the default column type in a report region HTML table is VARCHAR2 and thus that there is a default 4000 character limit on any such column values, would that be a fair assumption? I know that the actual report row size always used to be limited to a total of 32k but this limit is a new one to me.
If there is such a limit, does anyone have any suggestions on how to work-around it i.e. is it possible to redefine report region column values to be other datatypes/dimensions or should we be looking at using an alternative such as a pop-up instead?
Many thanks.

Hi Scott,
Okay, what we have is a fairly simple Dynamic Page with two report regions (both standard type of 'SQL Query'). The second report region is the one causing us the headache. The column headings are set to 'Custom' but apart from that everything seems as it should be.
The following query populates an HTML table being generated in the second report region (problem line in bold):
SELECT apex_item.hidden(7,task_id)||
apex_item.select_list_from_lov(1, estimate_type, 'TASKSMK', NULL, 'YES', 0,'** Select Task **',NULL, NULL) as "Task Type",
'<img src="/i/themes/aqa/required.gif" alt="Required Field" tabindex="999" />'||apex_item.text(2, description,30,4000,'required="true"') as "Work Item(s)",
dbms_lob.substr(apex_item.select_list_from_lov_xl(3, username, 'PEOPLE', NULL, 'YES', 0, '** Select Resource **', NULL, NULL),4000) as "Resource",
apex_item.text(4, days,5,5) as "Days",
apex_item.text(5, start_date,11,11) as "target Start (dd-mon-yyyy)",
apex_item.text(6, NVL(end_date,ADD_MONTHS(start_date,1)),11,11) as "Target End (DD-MON-YYYY)",
rownum link
FROM
(SELECT t.task_id,
e.estimate_type,
t.description,
t.username ,
t.days,
t.start_date,
t.end_date
FROM estimate e, task t
WHERE e.project_project_id = TO_NUMBER(:F172_PROJECT_ID)
AND e.active_yn = 'Y'
-- and t.days > 0
AND t.ese_id = e.id
--AND e.creation_date = (SELECT MAX(ei.creation_date) FROM estimate ei WHERE ei.project_project_id = e.project_project_id AND ei.active_yn = 'N')
UNION ALL
SELECT 0 task_id,
0 estimate_type,
NULL description,
'0' username,
NULL days,
sysdate start_date,
ADD_MONTHS(sysdate,1) end_date
FROM dual
CONNECT BY LEVEL < = TO_NUMBER(:P19_ROWS_CNT))
All appears well until the number of values being returned in the second LOV (retrieved by the apex_item.select_list_from_lov_xl) exceeds 4000 characters and then we get the error first detailed. The substr around the function isn't usually present, it was added during the debugging, if I allow one more character than the 4000 or remove the substr completely then I get the error again. If the same function is used to retrieve the LOV on a normal Dynamic Form field then all is well, it only seems to have a problem when present in the HTML table being generated.
Are we doing something silly here?
Thanks.

Problem with Column Sorting in Request Table View

We've enabled column sorting on the table view in an Answers request but it doesn't work when more than around 400 rows are returned. It works Ok when fewer than 400 rows are returned. Does anyone know if there is a specific limit to the number of rows where column sorting works?
Thanks,
Mike

I've dug into the query log a little more. When this request returns more than around 400 records and you click on a column heading to sort the table view, the query from the log is not changing to reflect the new sort order. It stays as whatever the default sort order was for the request.
Column heading sorting on other requests in different subject areas on this same server works fine. I've tested this other request with up to 6400 rows returning and it's sorting works.
All caching is turned off for the subject area.

Problem with column sort in myFaces dataTable

Hello,
In my dataTable I am trying to do a column sort on each column, When i click on the column header link nothing is happening. Could somebody please help. Please let me know if I am missing something.
Here is the code.
The jsf is as follows:
<h:panelGrid columns="1" styleClass="tableHeaderAction">
<t:dataTable id="fooS" value="#{supervisorsDto.tableRows}"
var="tableRow" rows"30" styleClass="dataTable"
headerClass="tableHeader" first="0"
columnClasses="string,string,string,string"
rowClasses="odd,even"
sortAscending="#{supervisorsDto.ascending}"
sortColumn="#{supervisorsDto.sort}"
preserveSort="true" >
<t:column>
<f:facet name="header">
<t:commandSortHeader columnName="lastName" arrow="false">
<t:outputText value="#{screen.lastName}" />
</t:commandSortHeader>
</f:facet>
<t:outputText value="#{tableRow.lastName}" />
</t:column>
<t:column>
<f:facet name="header">
<t:commandSortHeader columnName="firstName" arrow="false">
<t:outputText value="#{screen.firstName}" />
</t:commandSortHeader>
</f:facet>
<t:outputText value="#{tableRow.firstName}" />
</t:column>

<f:facet name="header">
<t:commandSortHeader columnName="loginName" arrow="false">
<t:outputText value="#{screen.loginName}" />
</t:commandSortHeader>
</f:facet>
<t:outputText value="#{tableRow.loginName}" />
</t:column>
<t:column>
<f:facet name="header">
<t:commandSortHeader columnName="team" arrow="false">

</t:commandSortHeader>
</f:facet>
<t:outputText value="#{tableRow.team}" />
<h:inputHidden id="key" value="#{tableRow.empID}" />
</t:column>
</t:dataTable>
</h:panelGrid>
The sort method in SupervisorsDto is as follows:
public class SupervisorsDto implements Serializable {
private String sort="lastName";
private boolean ascending= true;
@SuppressWarnings("unchecked")
public void sort(final String column,final boolean ascending)
Comparator comparator = new Comparator()
public int compare(Object o1, Object o2)
Supervisors c1 = (Supervisors)o1;
Supervisors c2 = (Supervisors)o2;
if (column == null)
return 0;
if (column.equals("lastName"))
return ascending ? c1.getLastName().compareTo(c2.getLastName()) : c2.getLastName().compareTo(c1.getLastName());
else if (column.equals("firstName"))
return ascending ? c1.getFirstName().compareTo(c2.getFirstName()) : c2.getFirstName().compareTo(c1.getFirstName());
else if (column.equals("loginName"))
return ascending ? c1.getLoginName().compareTo(c2.getLoginName()) : c2.getLoginName().compareTo(c1.getLoginName());
else if (column.equals("team"))
return ascending ? c1.getTeam().compareTo(c2.getTeam()) : c2.getTeam().compareTo(c1.getTeam());
else return 0;
Collections.sort(tableRows, comparator);
public void sort(String sortColumn)
if (sortColumn == null)
throw new IllegalArgumentException("Argument sortColumn must not be null.");
if (sort.equals(sortColumn))
//current sort equals new sortColumn -> reverse sort order
ascending = !ascending;
else
//sort new column in default direction
sort = sortColumn;
ascending = isDefaultAscending(sort);
sort(sort, ascending);
protected boolean isDefaultAscending(String sortColumn)
return true;
public String getSort() {
return sort;
public void setSort(String sort) {
this.sort = sort;
public boolean isAscending() {
return ascending;
public void setAscending(boolean ascending) {
if(ascending != this.ascending)
this.ascending = ascending;
Thanks!

I think I get really good at answering my own questions.
It seems when you select the sort option on a column you must also set the "Sort Sequence".

Drag-drop data column sorting

Hey guys,
Does any one know how to achieve drag-drop data column
sorting? I tried, but could not find an efficient way to do this.
It would be an awesome spry feature if possible, but if someone
else knows how to do this already it would help.
Thanks,
Timothy D Farrar

Hey guys,
We aim to be as compatible as possible with the other
frameworks but sometimes problem may exists. We need to see the
crashing pages to be able to determine the causes for the JS error
message and where the incompatibilities are located and either fix
the problems or help you to change your pages to work.
In this situation I suspect the issue appears because the
spry region is generated after the drag and drop code from the
script.aculo.us is instantiated and we destroy the initial elements
to which this widget is binded. In this situation the solution is
to instantiate the drag and drop after the region generate its
content by using the region observers. You'll have to put the drag
and into a separated function and register the code so the region
will call it automatically onPostUpdate.
We include in our documentation more details about the
Region
observer notifications. Please search the dedicated chapter
inside this doc: "Region observer notifications"

Itunes / ipod column sort locked?

I'm having the same problem with my iphone. When I click the "manually manage music, it prompts me that the iphone is synced with another library. Do i want to erase this iphone and sync with this itunes library?
Of course I dont want to do this! My iphone is "synced" with my computer at home, while at work, I'd like to listen to music to my iphone through my work mac (which has no mp3s on it) using itunes. Annoying!
Anyone find a third party solution to this?

Any help would be greatly apprciated and rewarded...

Hi Don,
be aware that after the method onHeaderClick(Event event) is executed the method doProcessBeforeOutput() is executed as well.
I look over your code and found the following:
1) In method onHeaderClick you sort the table model and store the table model in the bean
2) In method doProcessBeforeOutput() you create a new table model from scratch (in helper method tableViewFormat())and store it in the bean. Thus you overwrite the sorted model.
I suggest that you move the initial creation of the table model in method doInitialization(). Do not forget to store the created table in the bean. In method doProcessBeforeOutput() you retrieve the table model from the bean instead of creating a new one for every request.
Best regards,
Martin

ALV Sort problem

Hi Experts,
I have encountered a peculiar situation with respect to ALV, using sort. The problem is as follows:
1. I have an internal table with 3 fields, upon which I am supposed to implement a sort criteria on the first two fields.
2. My data is something like this, for ex:
abc 1 a
abc 1 b
cde 1 a
cde 1 b
3. I have applied sort criteria, on the first two fields and passed to the fm "REUSE_ALV_GRID_DISPLAY'.
4. Now the output is as follows:
abc 1 a
-- b
cde -- a
---   -- b
Here ( -- ) dotted lines mean the identical entry from the previous row...
5. My requirement is I want the output as:
abc 1 a
--- --   b
cde 1 a
---   -- b
I mean the sort critetia of the second column should follow the first(adjacent column) sort criteria
I hope it is clearly explained, and kindly let me know how this can be solved..
Thank you,
Shashi

Hi Bala,
The suggested solution is not giving the desired results..
This happens because, when i sort the entries i mentioned earlier, remains the same, even after the two explicit sort statements on the internal table.
Kindly check the same and let me know.

Shashi

Sort problem on dynamic query !!

Hi,
I have a dynamic query written in pl/sql, when I check "Sort" for each field in Report Attribute, error message raised up as "ORA-01785: ORDER BY item must be the number of a SELECT-list expression".
If I do not check Sort, it works fine. In my apps I need all fields sorted by user, how to fix this problem?
My query as below:
declare
query varchar2(2000):='select';
s_class varchar2(1000);
cursor c1 is select * from demo_preference;
begin
for c1_val in c1 loop
if c1_val.login is not null then
query := query ||' ' || 'login' || ',';
end if;
if c1_val.id is not null then
query := query ||' ' || 'id' || ',';
end if;
end loop;
query := SUBSTR(query, 1, length(query)-1);
s_class := '(NVL(:P2_class, ''%'' || ''null%'') = ''%'' || ''null%'' OR
EXISTS (SELECT 1 FROM apex_collections WHERE collection_name = ''P2CLASSCOL'' AND c001 = class))';
query := query ||' ' || 'from ming.reg_report_view1 where'
|| ' ' || s_class;
return(query);
end;

Maybe the internally mapped column used when you clicked on sort is not shown in the report. Try using aliases when you construct the query string, it could help apex internally in identifying a column even if its order changes for a different user. After all the column order in the code is dynamic and I guess even the no of columns displayed might vary both of which could make sorting on a column identified with a number, invalid.
How about displaying the report query somewhere, so that you know what is the exact query being processed, it might give you better information about the problem.
If the problem persists, then use a collection that is fetched those record using the same query string and change the report to refer the collection and then set column sorting on. This way apex would get confused on what columns are being sorted and it would just sort on a c001..c050 column as though it was a string(yes problems with number columns sorting when you do this).

Reports serialising when column sort attributes used

If an Apex user has two sessions and runs the same report page in both, then if the report uses column sort attributes (rather than an ORDER BY in the SQL), the second is blocked by the first; once the first completes the second then runs and completes. This appears to be because the user preferences for column sorting are being updated each time, even if they have not been changed.
This application demonstrates the problem:
http://htmldb.oracle.com/pls/otn/f?p=15827:2
Create 2 sessions using that URL. The page has a report based on ALL_OBJECTS with an item "Owner" to filter on. Enter "%" in the first session and press Enter and the report will run, taking about 1 minute. Meanwhile in the second session enter a specific owner (or just XXX) and press Enter. The second report will finish just after the first finishes, even though when run alone it only takes half a second or so.
Is this a bug?

Hi Tony,
If you're using this on unauthenticated pages, then the sort preferences are stored per user for the APEX_PUBLIC_USER (or HTMLDB_PUBLIC_USER), which is potentially why you're seeing the serialisation/dead-locking.
Could you perhaps use the suggestion by Scott in this thread -
Re: Report sorting affected by other users
To use the session ID as the APEX user (or anything else you prefer), to mitigate the potential for the deadlock? (It's worth trying and should take just a few seconds to test in your sample app?).

Sorting problem in standard vendor search help

Hi all,
I'm enhancing the vendor search help.
I found that there is a sorting problem in the original standard search help.
The 1st time to search vendor in the search help returns a correct list, then I just sort the vendor in ascending order. This time the column name of the hit list changes and mismatch the actual values.
Any one faced this problem before?
What's wrong are there ?
Thanks.

Thanks Peluka.
But even I don't enhance the vendor search help, I still found that the original standard version has this problem after sorting.
Is that the program bug?
Have anyone encountered this problem before?

Embedded images disappear on column sorts when viewing SSRS via url in an iframe

RE: SQL Server - 2008 R2 Reporting Services
We deliver an ASP.Net MVC (5) application and some of the views show/display SSRS report via url in an iframe (so the report is displayed vi the web viewer). There are images in the header of some of these reports which display correctly on the initial
view, but "disappear" when the user uses a report column sort and/or changes the report zoom (via the SSRS web viewer toolbar). There are other quirky behaviors as well (depending on the browser), but we are dealing with IE versions 8 thru 11. I've
already set the ReportViewer.aspx to use <meta http-equiv="X-UA-Compatible" content="IE=7">, and our application pages/views use <meta http-equiv="X-UA-Compatible" content="IE=edge">.
Does anyone have a "fix" for this? I know it's related to the ReportViewer.aspx and displaying the report(s) in an iframe, but I can't seem to find any information on how to fix the issue.

Hi,
According to your description, when you preview report through url in an iframe, the embed images can be displayed, images can’t be displayed after users used sort and changed report zoom.
To troubleshoot the problem, please refer to the following steps:
Run the report in Business Intelligence Development Studio (BIDS) to make sure that the images can be displayed correctly.
The issue may be relevant to compatibility of browser, please use different browser to check whether the issue persists.
If you are using embedded image of jpg type, please change the extension of the image to png.
Set the ReportViewer.aspx to use <meta http-equiv="X-UA-Compatible" content="IE=8">.
Here is a relevant thread you can reference:
