Aligning fields horizontally in af:query component

Hi friends,
i am developing a search region using the named criteria of my VO by dragging it. This created an af:query component in the search region. However the fields are displayed in rows in the search region. I want to align these fields so that all the fields are displayed in a single row. also how can I set the length of the fields.
Any ideas or hints how to do this.
Thanks in advance

Accessing fields of the af:Query Component

Hi all,
I need to get the value of a dynamic field that is added to the query component at runtime.
In my application there is field named "Member Id" which adds a "select one component" in the advanced search mode.
This "select one component" has a string value "self".
What I need to do is,
When the value "self" is selected from the "select one component" I need to use the Id of the user
as the "Member Id" for the search query.
Is it possible achive this by using af:query component ? or is there a different approch?
I'm using JDeveloper 11.1.1.0.1
Thanks,
Melaka

Melaka,
first create a custom View Object Class for your View Object from the Java Classes pane. Then override the buildQuery() method of the ViewObjectImpl by writing the following code:
@Override
protected String buildQuery(int noUserParams, boolean forRowCount) {
// call super.buildQuery() to allow the framework to build the query
String query = super.buildQuery(noUserParams, forRowCount);
// here you will modify the query
// if the query contains your keyword
if (query.contains("'self'")) {
// replace it with the actual user id
// return the modified query
return query;
I am sure there are other cleaner ways to accomplish this.
Consider for example using two separate attributes: one Transient for your "Member Id" query criteria - what is shown to the user - and another attribute actually mapped to a column that is used for querying. You set the value of the second attribute as the first one changes.

Auto suggest behavior for af:query component LOV fields.

Hi,
I am new to ADF development and need help on implementing auto suggest behavior to the LOV fields generated by af:query component. For inputList and inputCombo.. fields we can add af:autosuggestbehavior tag to enable this. How do we enable the same for af:query generated LOV fields.
Regards,
C.R

Thanks Timo for such a quick response.
JDev version we are using is 11.1.1.6.0
Unfortunately, we have gone too far with the AF:Query and Everything else is working apart from Auto-Suggest on AF:Query. Now will take a lot of time to implement and test. Also, users will have to spend considerable time to test it again.
Thanks and Regards,
Satya

Add custom field to af:query component?

Anyone had any experience overriding af:query copmonent? I need to add my custom search field (to query component), which would have a search icon next to it, and on click, a popup widow would open containing my custom task flow where I could select a record with certain value and on return that custom field (in query component) would get populated with selected value. I hope I'm being clear. Please point me to any useful information. Is that even possible? I use JDeveloper 11.1.2.3.4.0 Regards, Marko

Hi,
af:query is a component that comes as is. Its not designed for customization in that you can add your own fields. If you have a requirement for this then
1. expose a method on the VO Impl or AM Impl that expect arguments (your query parameters)
2. Use the arguments to populate bind variables used by a ViewCriteria
3. Apply the View Criteria to the View Object
4. Execte the View Object
5. Drag and drop the method from the DC panel as a parameter form
6. Ensure the result table PartialTrigger property is pointing to the button ID of the parameter form
7. Change whatever UI component you want to change in the parameter form
This gets you going ...

Af:query component added field not removed when remove icon is clicked

I have an af:query component on a popup dialog. In advanced mode when I add a field, the new field appears in the searchRegion followed by a red X remove icon. If I subsequently click that remove icon, the query refreshes, the red icon is gone, but the newly added field still remains. The query component is linked to a standard VO query executable in the bindings. There is no custom processing of the value, model, queryListener or the queryOperationListener. In all other respects the query component works fine. The only problem is a newly added field not being removed when the remove icon is clicked. Here's how the component is setup (an added wrinkle is that the query component is hosted in a Declarative Component, so that makes this code a little harder to decipher).
Does anyone know where I should start looking for this? Hopefully I don't have to implement my own queryOperationListener.
JDev version is Build JDEVADF_11.1.1.4.0_GENERIC_101227.1736.5923

Retrieve Filter Field from af:Query Component

I'm using an af:query component on my form and have pre-definied ViewCriterias that load the page. Each ViewCriteria contains one field that is used across all of my search criterias....I need to be able to retrieve this field in my backing bean and get the value of it. I need to know what the user is searching on for this one particular field (i.e. which will always be available in the af:query. I have the queryListener pointing to a method in my backing bean...does someone have some sample code on how to access the fields used in the query and then access the value of one in particular?
public void headerQueryListener(QueryEvent queryEvent) {
CommonHelperFunctions.resolveMethodExpression("#{bindings.AllChangeOrdersQuery1.processQuery}",
null, new Class[] {QueryEvent.class}, new Object[] {queryEvent});
// What can I add here to retrieve a filter field and then retrieve it's value??
The queryListener on my af:query component then calls this headerQueryListener in my backing bean.
Thanks.

I have tried the following code just messing around:
QueryModel varQueryModel = getQueryHeader().getModel();
List<AttributeDescriptor> attributeDescriptors = varQueryModel.getAttributes();
AttributeDescriptor ad = attributeDescriptors.get(3);
The attributeDescriptors has the information that I need. I can see the elements in my query and I can see that element 3 is the one I want, but it doesn't have the an _attrDef name but it does have an mAttrName and the mValues[0] mValue has the value that I'm looking for, but I'm having trouble figuring out how to access this information and retrieve what i actually need. I'm very new to Java and ADF so sorry if this is a basic Java question, but if anyone could point me to an example or some sample code, I really appreciate it.
Thanks in Advance.

Setting value dynamically in a field sitting within a af:query component

Hi
I have three cascading LOV (Site/Building/Room) and an input text field (Location) as part of a af:query component.
I want to populate Location field dynamically with a string based on the values selected in the LOVs like "%/<Site selected>%<Building selected>%<Room selected>%". If any of the LOV is left blank, the string should be adjusted automatically
How do I do it, a declarative way would be preferred. Please advise
thanks

Timezone effects on Date and Timestamp fields in af:query component

Hello,
I'm working on an ADF application where time zone is configured as follows:
* Dynamic View Layer time zone is configured in trinidad-config.xml file and bound to a session scoped value:
<trinidad-config>
<skin-family>fusionFx</skin-family>
<time-zone>#{sessionScope.tz}</time-zone>
</trinidad-config>* ADF BC time zone is configured in adf-config.xml file and bound to View Layer time zone:
<adf-config>
<user-time-zone-config xmlns="http://xmlns.oracle.com/adf/usertimezone/config">
<user-timezone expression="#{adfFacesContext.timeZone.ID}"/>
</user-time-zone-config>
</adf-config>The problem here is that Dates and Timestamp values work as expected all over the application except for the af:query component. When displayed as af:inputDate in af:form, Dates and Timestamp values are NOT getting converted to the time zone (TZ) configured in trinidad-config.xml file, whereas TimestampTz and TimestampLtz are. However, when displayed in af:query component, Dates and Timestamp values are automatically converted to View Layer TZ after a search has been performed.
For example, say View Layer TZ = US/Pacific and we enter 01/jun/2011 as a search criteria of type Date and then click on the Search button. The displayed value automatically changes to 25/nov/2011, that is, it gets converted to the WLS JVM time zone, which is set to Europe/London.
Is conversion of Date and Timestamps in af:query component the expected behaviour or could this be a bug?
Is there any way to avoid this conversion?
Thanks in advance

Setting default value read from user session, for an LOV in Query component

I want to set the default value of a field in VO that participates in a named view criteria and thereby in Query component. That field is configured with an LOV by mean of a view accessor. The values are Y and N and the corresponding display strings obtained from view accessor are true and false respectively.
I am able to set the default value by setting the value of the criteria item corresponding to that field in view criteria. I am setting the value as either Y or N and I am able to corresponding display string as per the view accessor, on the query component when it is rendered.
I want to read the defauilt value from the ADF BC user session and set it as default value. I tried setting the values as "adf.userSession.userData.usageFlag". Iam ensuring that the attribute usageFlag is set before the view activity that has the query component is invoked. But this is ending up showing no default value in the Query component when rendered.
Can any one let me know how to go about with this?

I made up your table since you didn't provide some example, but I'm sure this will give you the picture:

Class Cast exception when clicking Search Button in Query component

Hi
We have to implement the Query component in ADF programmatically.. We are using Toplink as the Model layer for ADF.
We followed the Web User Interface Guide for ADF development, Chapter 12 (Using Query Components) for the same.
We already have implemented the following classes:
1) QueryModel
2) QueryDescriptor
3) AttributeDescriptor
4) ConjuctionCriterion
5) AttributeCriterion etc.
We are able to see the Search panel in UI with selected fields in Basic as well as Advanced mode.
When we click on Search button, we are getting Class Cast exception.
The stacktrace of the exception is below:

I am working on a project that utilize Oracle Ultra Search that will crawl and tag documents in the database.
The initial code that uses pure JDBC was working fine, but when we switch to get database connection from dataSource, we are getting classCast exception inside Oracle's ultra search. The problems is that the class we get from dataSource.getConnection() returns
"weblogic.jdbc.wrapper.JTSConnection_oracle_jdbc_driver_T4CConnection". But Oracle UltraSearch is not expecting that.
Is there anyway to unwrap the connection that we get from dataSource ? I tried casting to OracleConnection,
assign the connection to "oracle.jdbc.driver.T4CConnection" without any success.
Any help would be appricated.
ThanksHi Gary. If the code you want to run is running inside WebLogic, such as in a JSP,
then look for our documentation on our JDBC extension 'getVendorConnection()". It
will get you a direct Oracle connection for their mis-declared UltraSearch
classes (they declare they take java.sql.Connection, but they really demand a
concrete thin driver connection. No other Oracle driver will be given a chance).

Programmatically Load Query Component on Page Load

Hi All.
We have a requirement in which we need to populate the fields of a query component and execute the query...upon loading of the page.
Our use case:
We have a page in which there is an analytic showing counts of requests in different status (i.e. Open, Closed, In Process).
Status Count
==== ====
Closed _5_
Open _3_
In Process _6_
When the user clicks on the count (which is a hyperlink) we want to take them to the "Search for Requests" page with the criteria filled out and the query automatically executed. For example, if the user clicks on the count of "5" (for Closed)....they will be transferred to the "Search for Requests" page. The query field of "Status" will be defaulted with "Closed" and the query automatically executed (with the 5 requests shown in the result set).
We are using page fragments (.jsff) in bounded ADF task flows.
I am thinking that we need to set up a default activity in the "Search for Requests" task flow that will call the AM Impl method to handle this on the model side but I am unclear on how to programmatically set the criteria that is used in a query component?
Any help is appreciated.
Thanks.

In the processRequest of your controller you can invoke a method in the AM which in turn invokes a method in the Search VO which sets the where clause and executes the query.

Query regarding : af:query component

In af:query my requirement is to add one search field which looks like :
"*Label*" "*Drop down List*" "*Input Text field*"
For the other fields which have only
"Label" and one other Component type i am using QueryDefinition.addAttributeDefinition But how to add two components with Label.

Not sure if you can change the af:query component to do this , but you can easily build your own search form and in this form build your own layout.

Validations on these fields:
1. When user enters value in field 1 and tabs out, a background plsql should execute and return the value to field 2. If no value returns, then and exceptio should raise for field1.
2. Field 3: when the user enters a value and tabs out, it should automatically convert to UPPER case.
3. Field 5 and field 4 are date paremeters. Field 5 should be disabled until a value enters in field4
4. Value in field 5 should be validated agaigst field 4 it should always > field 5
5. Once user hits find button, it should check for atlease one search criteria other wise it should prompt the user to enter atlease one search criteria. (ALong with above 5 validations). Popup should come here.

I'm not sure you'll be able to achieve all of this with the af:query component.
Here is how to do the dependent lists:

It might be easier to build this type of search form something like executeWithParams - see:

Bug : Customizing af:query component

Hi,
I am using jdev 11.1.1.6.0 version. I want to know how i can customize the error messages displayed by an af:query component. Example: suppose i am using advanced search on a field called productId. The search criteria used is 'Between' and if i mention only one value in the text field and the other text field is empty. Error message pops up saying that Attribute ProductId is required. I want to customize this message with my own error message. How can i achieve this ?
Thanks in advance.

And One more question is , how to define the size of the "Search and Select popup window" when it is used inside the af:query.
Thanks In Advance,

Thanks Frank.
Can we conditionaly set the Queryable property of a VO attribute. And don't you think that option should be provided to select the attributes also which should appear in the search window?
And how we can set the width and height of the Search and Select popup window when user clicks the LOV icon?
Thanks much
Vikram
