Dynamic view size

Hi,
is there a possibility in Web Dynpro to change the size of a view dynamically by the mouse?
I have two views and it should be possible to shift the border between them like in normal window-applications (e.g. outlook).
Or is there a possibility to develop a layout for the portal where this is possible?
I would be happy if someone can give me an advise or a link.
Thanks

Paging issues using a dynamic view object...

I am working on an application that uses JAG to generate JSP pages, i had the requirement to use dynamic view objects where the view object query is generated at runtime. The rest of the application is more or less the same... I used the defult functionality provided by TableScrollButtons.jsp file for paging. Now the problem im facing is that while the '>' and '<' buttons are working fine, i cant seem to navigate to the pages using the drop down...
With the default handler, whenever i select the range the range displayed remains the same ie 1-10, 10 being the rangesize, but the rows are refreshed with values from the next page. Also, if the next page is the last and is incomplete, then the rows are pushed in from the bottom, so that the last page is always full...I tried the tuning panel in the view object edit dialogue and all settings are fine (i think)...could anyone please tell me what i am doing wrong??

could it be because i am using a dynamic view object with dynamic bindings? i am using the preparemodel() method in the action as follows...
protected void prepareModel(DataActionContext ctx) throws Exception {
inferRangeBindingIfUnset(ctx);
ctx.getBindingContainer().setEnableTokenValidation(false);
String sql = ctx.getHttpServletRequest().getParameter("sql");
String cost=ctx.getHttpServletRequest().getParameter("CostCostCent");
String event=ctx.getHttpServletRequest().getParameter("event");
if (sql != null && event == null) {
setupDynamicQueryAndDynamicBindings(ctx,sql.substring(1),cost);
if (retrieveOnlyCurrentPageFromDatabase()) {
ViewObject vo = getIterForPaging(ctx).getViewObject();
if (vo.getAccessMode() != ViewObject.RANGE_PAGING) {
vo.setAccessMode(ViewObject.RANGE_PAGING);
// if(event==null)
super.prepareModel(ctx);
ctx.getBindingContainer().setEnableTokenValidation(true);
if (ctx.getEvents() == null || ctx.getEvents().size() ==0) {
setPage(ctx,1);
setLastPage(ctx,getIterForPaging(ctx).getRowSetIterator().getEstimatedRangePageCount());
else if(event.equals("setRangeStart")) {
setPageFromRequest(ctx);
}

Is it possible to change dynamicaly VC table view size (width/heigth)?

Hi gurus!
So the question is: Is it possible to change dynamicaly Visual Composer table view size?
Particularly I'm interested in changing table-view height; the objective is not to use table-view paging option, instead to show all returned data rows at once.
Thanks in advance!
--- Kaspars

Hi Kaspars,
I would say there is atm no possibility to change the table view size dynamicly, because you can't input a formula into the size field so the size is fixed as you enter it.

Select from Query ? / Dynamic view ? Anything else ?

Hello,
This could be a bit challenging. (or maybe not, i hope)
I have to create a report which is based on 3/4 tables with pretty complex SQL.
Step 1. I have to use views (in the database currently) to select data from these tables.
Step 2. Then create the next set of views (in the db) based on the previous views.
Step 3. Then finally join the last set of views in Reports and create the report based on the PARAMETERS entered.
This was fine, until the client changed the criteria. Now the views have to be created but the PARAMETERS affect the FIRST set of views.
That is, the views in the FIRST STEP will have a where condition based on the parameters at RUN TIME.
I was wondering about how to do this ?
1. Can I use dynamic views (in db) passing the where condition parameter to the where clause ? Alternatively use DDL in Reports.
OR
2. Create a query in Reports and create subsequent QUERIES BASED ON THE FIRST QUERY (like MS Access). Can this be done ?
3. Any other way ?
If you need any clarification, I can provide that.
THANKS for taking the time to read it. It would be great if you could give me any ideas.
Pat.

hello,
you might look into REF-CURSOR-QUERIES for this particular case. it might help.

Dynamic view creation in Flex

I am new to Flex web applications and I am doing research to see if functionality
contained in an existing web application can be replicated in a Flex web app.
We currently have a JSP / Struts based web application that creates a data entry
web view dynamically based on information that describes the different widgets and
their view locations as recieved from the application backend. We are looking at
migrating this application and this functionality to Flex.
When User X selects 1 of any number of data entry views, the Flex application would
receive data from the back end that contains information describing the different widgets
to display on the dynamic view: what type of widget to display ( text field,combo, line,
box, etc), the pixel specific positional information as to where each widget exists in the
view. These data entry views are not something the Flex developer designs or knows
what to expect from the backend. Flex has to generate the view on the fly based on the
information that describes the view.
The question: I fully expect there to be coding within the action scripts; before trying to
learn how to do this, is this something that Flex support.
Thanks,
Brian

Yep, we do something similar. We had to build out the infrastructure, but It works fine. E.g.,
var bDesc:XML = <button x="10" y="5" label="hello world" color="red"/>
var b:Button = new Button();
b.label = bDesc.@label;
b.x = bDesc.@x;
b.y = bDesc.@y;
b.setStyle('color', b.@color);
addChild(b);
In your app, the actual description (XML or other format) would be coming from the server. Then you just add it to the display list (and wire in any event handlers if necessary). In a real setting, you'll need error checking and a more formalized way of doing this, but it works reasonably well. No major snags.

How to create dynamic View Object and Dynamic Table

Dear ll
I want to create a dynamic view object and display the output in a dynamic table on the page.
I am using Jdeveloper 12c "Studio Edition Version 12.1.2.0.0"
This what I did:
1- I created a read only view object with this query "Select sysdate from dual"
2- I added this View object to the application module
3- I created a new method that change the query of this View object at runtime
 public void changeVoQuery(String dbViewName) {
 String sqlstm = "Select * From " + dbViewName;
 ViewObject dynamicVo = this.findViewObject("DynamicVo");
 if (dynamicVo != null) {
 dynamicVo.remove();
 dynamicVo = this.createViewObjectFromQueryStmt("DynamicVo", sqlstm);
 dynamicVo.executeQuery();
4- I run the application module for testing the method and I passed "Scott.Emp" as a parameter and the result was Success
5- Now I want to show the result of the view on the page, so I draged and dropped the method from the data control as a parameter form
6- I dragged and dropped the view Object "DynamicVo" as a table and I choose "generate Column Dynamically at runtime". This is the page source

Have you seen Shay's video https://blogs.oracle.com/shay/entry/adf_faces_dynamic_tags_-_for_a
All you have to do is to use the dynamic table to get your result.

Updatable , Dynamic VIEW OBJECT ??

Hi ,
I want to create a dynamic VO which is updatable.
I dont have any information about the table on which my View Object is based on, at DESIGN TIME. At run time I create query for the view and create dynamic view using AM.createViewObjectFromQueryStmt(String, String) but this kind of view will not be an updatable view.
I think if I use createViewObjectFromQueryClauses() from entity, it will be updatable,,,but in that I will have to create entities for all the table in my schema ..which sounds BAD...
is there any thing as DYnamic Entities ??
or any other trick to do this.....
BC4J should support something like changing QUERY_DATA_SOURCE_NAME at runtime in oracle forms.. which allow you to update record.
Thanx,
Prasoon

Hi Prasoon,
Steve Muench's "Dive Into BC4J" page has the following example: http://radio.weblogs.com/0118231/stories/2003/07/15/creatingUpdateableMultientityViewObjectDefinitionsDynamically.html
But this is based on pre-defined Entity Objects. It might give you some ideas, though.
Good luck!

Dynamic view object loses bind variables after passivation

I am creating a view object definition/view object programmatically in Jdev 11.1.1.2.0. The query requires a named bind parameter. All was working fine but now I am testing with app module pooling disabled and the bind variable is not being restored after passivation -- it's like the definition has disappeared or something.
Here is my VO creation code:
ViewObject vo = findViewObject("FinalistsWithEvalDataVO");
if (vo != null){
vo.remove();
ViewDefImpl voDef = new ViewDefImpl("FinalistsWithEvalDataVODef");
 // I add a bunch of viewAttrs here...
voDef.setQuery(fullQuery);
voDef.setFullSql(true);
voDef.setBindingStyle(SQLBuilder.BINDING_STYLE_ORACLE_NAME);
voDef.resolveDefObject();
voDef.registerDefObject();
vo = createViewObject("FinalistsWithEvalDataVO", voDef);
vo.defineNamedWhereClauseParam("Bind_SchlrAyId", null, new int[] {0});
vo.setNamedWhereClauseParam("Bind_SchlrAyId", new Number(1)); //For testing
vo.executeQuery();
The query executes fine right there and then the VO seems to passivate fine. I even see the bind var in passivation:
<exArgs count="1">
<arg name="Bind_SchlrAyId" type="oracle.jbo.domain.Number">
<![CDATA[1]]>
</arg>
</exArgs>
But then when it reactivates prior to rendering the page, it invariably throws a missing parameter exception and this in the log:
<ViewUsageHelper><createViewAttributeDefImpls> [7409] *** createViewAttributeDefImpls: oracle.jdbc.driver.OraclePreparedStatementWrapper@1af78e1
<ViewUsageHelper><createViewAttributeDefImpls> [7410] Bind params for ViewObject: [FinalistsWithEvalDataVO]AwardViewingServiceAM.FinalistsWithEvalDataVO
<ViewUsageHelper><createViewAttributeDefImpls> [7411] ViewUsageHelper.createViewAttributeDefImpls failed...
<ViewUsageHelper><createViewAttributeDefImpls> [7412] java.sql.SQLException: Missing IN or OUT parameter at index:: 1
I have worked on this for hours and can't see anything wrong. Like I said, it works fine when not forcing passivation...
Any help would be appreciated.
Thanks.
-Ed

@Jobinesh - Thanks for the suggestions. I have read all the documentation I can find. Everything works fine without passivation. Everything still breaks with passivation. I have given up on trying to get the bind variable to restore after passivation and am currently just building the query with all values embedded in the query rather than bind variables. This is bad practice but avoids the problem. However, now that I avoided that obstacle, I'm on to the next issue with passivation of this dynamic view object, which is that the current row primary key apparently cannot be reset after activation. I get the following error:
<Key><parseBytes> [7244] Key(String, AttributeDef[]): Invalid Key String found. AttributeCount:1 does not match Key attributes
<DCBindingContainer><reportException> [7254] oracle.jbo.InvalidParamException: JBO-25006: Value 00010000000A30303033383133343734 passed as parameter String to method Constructor:Key is invalid: {3}.

 at oracle.jbo.server.ViewRowSetIteratorImpl.activateIteratorState(ViewRowSetIteratorImpl.java:3877)
I've been trying various workarounds for over a day now with no luck. Very frustrating.
Thanks for trying to help.

Get bind variables of a dynamic view object

I seem unable to retrieve the bind variables for a dynamically created view object, even though I can do the same thing for a regular view object.
Here is the code:
newVO = repServ.createViewObjectFromQueryStmt("newQry",strSql);
VariableValueManager vvm = newVO.ensureVariableManager();
if (vvm != null)
Variable vars[] = vvm.getVariables();
vars will be empty, even though the sql statement in strSql has bind variables in it.
Is there any way to determine the bind variables of a dynamic view object?
Thanks!

I got the same problem as yours and still could not find any way out.
However, as I can see, you wanted to get VariableValueManager of newly created ViewObject that may be not available at this moment.
If you find way to solve the problem, please help.
Cheer,

Lov based on a dynamic view object

Build JDEVADF_11.1.2.0.0_GENERIC_110531.1615.6017
Hi,
I have a database table containing a column with the Name of a Table as content.
I created a dynamic view and overwrite this with a method in Appmodule.
Then I add to the element in the main view the Lov. I execute the method in JSP page.
But the SelectOnechoice list is empty!
Where is the problem? How can I create a Lov based on a dynamic view object?
Thanks in advance and best regards
Edited by: NewBB on 12.08.2011 00:53

Hi Neliel,
thank you for your reply.
My problem is not the same. I can also see my dynamic view objects as selectonechoice. I have a table T1 has a column t1c1 (Number),
another table T2 (dynamic view object) with two columns t2c1 (Number) and t2c2 (varchar2).
In my application I want to represent the values of t1c1 as selectonechoice with the values of t2c2.
and that does not work. My list is empty. Any idea???

Creating and Accessing a Dynamic View Object

Hi,
I'm needing to create a Dynamic View Object so to have the ability to modify the FROM and WHERE clauses in an SQL statement.
I then need to view all the columns and rows in an adf table or something similar.
I've read up a fair bit on similar situations, however I'm struggling with the basic framework of building the View Object.
I know I'm wanting to use ..createViewObjectFromQueryStmt..but just unsure of the syntax in using it, especially connecting the VO to an Application Module.
This is similar to what I've got now, located in AppModuleImpl.java
    public void createDynVO(ApplicationModule appMod, String FROMclause, String WHEREclause){
    String SQL = "SELECT JOURNAL_NAME, PERIOD_NAME FROM " + FROMclause + " " + WHEREclause;
    ViewObject vo = appMod.createViewObjectFromQueryStmt("DynamicView", SQL);
    vo.executeQuery();But how does it know what the application module is?
Any help would be greatly appreciated!
-Chris

Ok, I've actually modified my approach to this.
I've created a View Object in the design view, added it to the App Module, and then created an iterator and bound an adf table to that iterator.
The View Object which I created has the same column names as what I am going to be getting later down the track.
Everything is working perfectly, except that I can't seem to bind variables to the WHERE clause.
Below is what I have got running:
    public void recreateDynView(String FromClause, String whereCompany, String whereDepartment) {
         String sql_PAGE_ITEM1 = " AND PAGE_ITEM1 LIKE :P_PAGE_ITEM1";
         String sql_PAGE_ITEM2 = " AND PAGE_ITEM2 LIKE :P_PAGE_ITEM2";
         findViewObject("DynamicView1").remove();
         String SQLStmt = "SELECT PAGE_ITEM1, PAGE_ITEM2, PAGE_ITEM3, LINE_ITEM FROM " + FromClause;
         ViewObject vo = createViewObjectFromQueryStmt("DynamicView1",SQLStmt);
         vo.setWhereClause("1=1");
           if (whereCompany != null && whereCompany.length()>0){
               vo.setWhereClause(vo.getWhereClause() + sql_PAGE_ITEM1);
               vo.defineNamedWhereClauseParam("P_PAGE_ITEM1",null,null);
               vo.setNamedWhereClauseParam("P_PAGE_ITEM1",whereCompany);
           if (whereDepartment != null && whereDepartment.length()>0){
               vo.setWhereClause(vo.getWhereClause() + sql_PAGE_ITEM2);
               vo.defineNamedWhereClauseParam("P_PAGE_ITEM2",null,null);
               vo.setNamedWhereClauseParam("P_PAGE_ITEM2",whereDepartment);
         vo.executeQuery();
       }However whenever I input a value into one of the bound variables, I get the following error on the page.
   1. JBO-29000: Unexpected exception caught: oracle.jbo.InvalidOperException, msg=JBO-25070: Where-clause param variable P_PAGE_ITEM1 needs ordinal index array.
   2. JBO-25070: Where-clause param variable P_PAGE_ITEM1 needs ordinal index array.In the view object which i created at design stage, I've set the binding style to Oracle Named, so it should be alright. But obviously since I'm removing the view object and creating another version of it, it doesn't have the same binding style attached by default?
Is there a work around for this? I'm so close!

Master-detail with dynamic view object

How can you create a view link with a view object that is dynamic? I have created a master-detail relationship on a UIX page. I change the master view object at runtime using a view definition and SQL and then I bind the view object to an iterator on a UIX page. I need the new dynamic view object to maintain the link between the detail view object. Is this possible?
The reason why I have to change the view object at runtime is because I am implementing a search module and the tables in the from clause can be modified at runtime so I need to have a dynamic view object.
Thanks,
Sanjay

After playing around with ViewObjectImpl's setQuery() method some more I found out that this solution might not work for me due to the following reason: when the user tries to sort a column in the result table, the original contents of the view object get executed instead of the run time query.

I would like to go back to my original solution that included creating a view definition based on the runtime query and then creating a view object from that which I bind to the RowSetIterator. The missing piece to the master-detail functionality is with the detail Iterator being in sync with the master. I have tried the following but I get a ClassCastException 
DCIteratorBinding detailBinding = ctx.getBindingContainer().findIteratorBinding("DetailIterator");
detailBinding.getViewObject().setMasterRowSetIterator(masterBinding.getRowSetIterator());

here is the relevant stack trace:
java.lang.ClassCastException

How to create a dynamic view

I have 5 tables
of which one table is transaction table which stores all the trasanctions
it has near about 30 colms
from which i need create a dynamic view...
where user have to passed 5, 6 parameters and get the result .
how can i create a precompiled view ..

Why do you want to create a dynamic view.
It's a bad practice. You had already all column names.
I think , you can simply create a static view in design time.

How to bind to a dynamic View in UIX

I wish to have a UIX page access data from a dynamic View (i.e. the View is created at runtime). Since the View is not created at design time, I cannot create bindings for it in the UIX page's UIModel. Therefore, how do I reference this view in the UIX page?
Brad

Sanjay,
No -- but I'm experimenting with something simillar to what you mention. Actually, there is a way to iterate over each element if you made the childData attribute of your contents child of the messageChoice your rangeSet, i.e.:
<messageChoice>
<contents childData="${bindings.myIterator.rangeSet}">
<option text="${uix.current.myfield}"/>
</contents>
<messageChoice>
The problem is that this causes a problem with the subsequent submit, the current row, and what selection shows when the page is re-rendered. I am becoming more convinced because of this and some other things I've run into that there are either problems with using ViewLinks, or problems in UIX components where ViewLinks are involved. I'm pretty much abandoning use of ViewLinks altogether. I haven't seen much of anything work with them that isn't done exactly like tutorials and examples. And with regards to those, most tutorials and examples offer very little UIX help (most of them are JSPs), and even the ones that do have in-a-vaccuum style in-line databinding rather than database databinding (you'd think Oracle, a database company, might actually use database examples), which doesn't clarify a bunch of issues someone writing a reall application runs into.
As to an answer -- no unfortunately. Getting an answer to any ADF/UIX question is a time-consuming, frustrating, and most often fruitless process. Of my 45 some-odd posts on this forum, about 30 of them are unresponded-to posts.
