How to refresh an image's source value

I have an image component in a page fragment. When the page opens the image's source is set to the URI for a gif
What I want is to be able to update the URI to another image once a managed bean's property value changes.
The image component is bound to a managed bean property, pageAnimationImage.
I'm new to ADF and tried to set the partial trigger when the property value is set and also set the image's clientComponent to true
AdfFacesContext.getCurrentInstance().addPartialTarget(pageAnimationImage);
I searched this forum and other blogs but couldn't find anything related.
I'd really appreciate it if someone has a suggestion or point me to a related case.

You can try to bind the component to broader scope e.g. pageFlowScope or applicationScope and see if this works.
One other thing to try is to search for the component via its id
// find a jsf component
private UIComponent getUIComponent(String name) {
FacesContext facesCtx = FacesContext.getCurrentInstance();
return facesCtx.getViewRoot().findComponent(name) ;
}The method should find the component by its id. If you find it this way use the returned component to set the ppr on it with
// PPR refresh a jsf component
UIComponent image = getUIComponent("MyImageID");
if (image != null)
AdfFacesContext.getCurrentInstance().addPartialTarget(UIComponent);Timo

How to refresh an Image component

Hi,
jdev 1.1.1.5
I have a parent page with a table to show employees and a tab to show detail of employees
Detail is in a Region and is sharing the same datacontrol with parent page and i don´t have any parameter in task flow.
Sincronization Parent - Detail works fine using Partialtriggers.
Detail Region has a button for upload an image and another button to process the image and an Image component(by servlet) to show it.
Process button call an operation exposed in AM, This method do Insert or Update in IMAGE TABLE.
The problem is than image is not refreshed until i do full refresh the page.(but only occurs when updating the image, for insert the Image component show the new image)
I tried this code at end of process button logic but i can't achieve refresh the image.
public void saveFileUploaded() {
      oper =
          bindings.getOperationBinding("myMethodInAM");
       Map args = operaImatge.getParamsMap();
       args.put("empId", empId);
       args.put("imatgeBlob", createBlobDomain(file));
      oper.execute();
// try refresh entire region method 1
       AdfFacesContext.getCurrentInstance().addPartialTarget(JSFUtils.findComponentInRoot("r1"));
   // try refresh image component
       AdfFacesContext.getCurrentInstance().addPartialTarget(JSFUtils.findComponentInRoot("imageEmp"));
// try refresh region method 2
       RichRegion region = (RichRegion)JSFUtils.findComponentInRoot("r1");
       region.refresh(JSFUtils.getFacesContext());
}Any suggestion?
Thanks in advance

Hi,
I have updated the use case at first message.
you wrote
you have a binding to the component that is holding the image.. and then refresh the container region..
that would refresh the image inside.
can you give two cents?
i just created a binding for image component but
what must i do?
Remember
the button for process image (operation exposed in my AM service) and Image component(by servlet) are in the same .jsff.
Means the changes occurs in same jsff without interaction with parent page.
Thanks,

How to refresh the table after change value in the VO programatically?

Hi,
I like to update my table by using a popup. My problem is that the table does not refresh after I change the value in the table's VO by the popup.
There is another table in the popup, and the popup is triggered by a command button. An af:showPopupBehavior is nested in the button. The method of the button in backing bean is as following,
public void accountcodeButtonClicked(DialogEvent dialogEvnt) {
ViewObject volisttable=am.getAcChartValidateView1();
String nowcode=volisttable.getCurrentRow().getAttribute("Code").toString();
ViewObject vobasetable=am.getGlDetailView1();
vobasetable.getCurrentRow().setAttribute("AccountCode",nowcode);
The partialTrigger of the base table's column AccountCode points to the triggering button.
I do not know why the base does not refresh after the above method is executed.
Please me.
Stephen

Hi,
kind of a shame that after so many years of ADF the message that updates should be through the binding layer hasn't gone through ;-)
You change the underlying business service, which doesn't impact the binding layer the way you do it. So here is what you can try in the same order
- 1. RequestContext.getCurrentInstance().addPartialTarget(<table reference>)
- 2. If 1. doesn't show the changed data, try and re-execute the iterator that is the base of the table. If this works then the effect you see is caused because you ignore using the binding layer

How to Refresh The Page When The Value of selectinputData Changes

Hi;
I have a select input date component and I want to refresh the page when the value of selectinputdate changes. What is the way to do it?
Also what is the way to do the same thing with choosedate component?
Thank you very much...

Hi Turhan,
You may want to read about the Partial Page Refresh (PPR) capabilities in ADF Faces. You can make the selectInputDate's partialSubmit property "true" and then cause the specific components you wish refreshed have their partialTriggers property set to the ID of the selectInputDate.
Hope this helps,
John

import java.sql.PreparedStatement;
if ("YourEventID".equals(pageContext.getParameter(EVENT_PARAM))) // replace your event id created above
Inside if statement Add code to handle sql statement .
try
String Query = " "; // write any single SQL statement along with bind parameter inside " " , in your case it should be update statement

How to refresh .swf file whose source data is only using "EXCEL"

Can Some one help me out with this please.........
I developed a dashboard using excel (embedded in xcelsius 2008) and then exported it to .swf file.
Now when the data changes in .xlf file. I want my swf file to refresh the data.
Thanks in Advance

Hi,
   Read the below instructions extracted from KB Article 1424833 and see if it helps
XML files need to be designed in a specific structure in order to work correctly in Xcelsius 2008. Below are some important conventions:-
1) The XML code should start and end with data tag like <data>...</data>.
2) Row and column tags must be used to encapsulate data.
3) Everything is case sensitive.
4) While inserting a range in XML data connection, the range name should be similar to the variable name defined in the XML code.
The xml code should look like this:-
<data>
<variable name="ExampleRange">
<row>
<column> Row1 Column1 value </column>
<column> Row1 Column2 value </column>
<column> Row1 Column3 value </column>
</row>
</variable>
</data>
In Xcelsius, we have to give range name=ExampleRange and then assign the Excel cell to load the data.
Regards,
Ken

How to Refresh "Internal table values" in User EXIT.

Dear All,
My requirement is to place some checks in exit ZXQQMU20 in different tabs from the TCODE IW21 . IW22 etc.
Now after placeing the checks towards the different tabs while doing "NOCO" from IW21 the conditions are fullfilled but
when i go ahead to modify the created "NOCO " from the TCODE IW22 by deleting the created values and saving in IW22 , the conditions written in the exit are still satisfied eventhough i have deleted the values in IW22.
The reason for this is that the tables which are there in the exit ZXQQMU20 T_VIQMFE , T_VIQMUR , T_VIQMMA
still contains the old values which were there at the time of creation of "NOCO" in IW21 .

Hi, I was thinking just like XVBAP and YVBAP values in the USEREXIT_SAVE_DOCUMENT.
Plz check u have x /y versions or tables like _old/ _new suffixes and then move the value accordingly.
otherwise there may be inconsistency.

How stop PS6 from removing the DPI value from an image when using "save for the web"?

How stop PS6 from removing the DPI-value from an image when using "save for the web"?
Example:
- Open a tif image, that contains a dpi value (resolution).
- Use the splice tool in PS6.
- Export the slices with "Save for web", as gif-files.
Then the dpi value is removed, the gif files has no dpi value (it's empty).
How can we stop PS6 from removing the dpi value when using "save for web"?
OR:
When using the slice tool, how can we save the sliced pieces without PS removing the dpi value?

you can make your art go a little bit over the bounds. or you can make sure your artboart and art edges align to pixels

How to remove target node if source field value is empty SAP PI Mapping

Hello,
how to remove target node if source field value is empty in graphical Mapping.
Like if
MIddle name in source filed is empty, I would like to eliminate target field from out put XML.
Thank you
John

Hi Jhon,
If you want to remove all empty tags and you dont to complicate your message mapping, you can use a XSL, after the message mapping, to remove all the empty tags:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="*[not(@*|*|comment()|processing-instruction())
     and normalize-space()='' ]"/>
</xsl:stylesheet>

How to define source value for filtered recordset (ASP)

Hi,
I'm using ASP & CS4. I have a search page which upon submission sends form parameters to a results page. The results page matches the search parameters to a recordset and returns the appropriate record/s.
How can I take one of the values from the returned filtered recordset (which wasn't one of the original variables/parameters), and use it as a value to filter another recordset from another table? Do I have to create a parameter from that value, or can it be done in a SQL statement?
Many thanks

How many results are returned from the first recordset? Where is the second recordset to be displayed?
If the first RS returns a single row and the second RS is displayed on the same page, you don't need to create anything. Just use the value of the column you want in the SQL statement. If you need to pass the value to another page, you can either set a session variable or pass the value in the querystring.

Hi,
byte[] img = wdContext.nodeYywwwdata_Import_Input().nodeOutput().nodeOutMime().currentOutMimeElement().getLine();
use this code to create resource and you need to set this value to the context created to display the image suppose in the image UI and set the source property with this attribute:-
IWDResource res=WDResourceFactory.createCachedResource(b,"MyImage",WDWebResourceType.JPG_IMAGE);
IPrivateAppView.IVn_ImageTabElement imageEle=wdContext.createVn_ImageTabElement();
imageEle .setVa_Name(res.toString());
wdContext.nodeVn_ImageTab().addElement(imageEle);
Hope this may help you.
