BIRT ODA designer state

srisaibabu

Hi All, 
 
I have created BIRT ODA, it is working fine, but I am not able to save UI state. because user can change the query again while previewing results. 
 
 
private void initializeControl( ) 
{ 
/* 
* To optionally restore the designer state of the previous design session, use 
* getInitializationDesignerState(); 
*/ 
} 
 
Above method has a comment, which stats designer state can be restored using getInitializationDesignerState() method, but it always returns null. 
 
Please let me know, if anyone of you have used this method to restore the UI state. 
 
Regards, 
Sri Sai

Hi Sri,

you can have a look at the project that i shared recently. It is a Excel ODA driver.
I customized the data set dialog as well and had same problems. You can check out the project from google code or browse the code using the google web interface:
http://code.google.com/p/birt-spreadsheet-datasource/source/browse/#svn/trunk/de.c-brell.birt.report.data.oda.spreadsheet.ui/src/de/cbrell/birt/report/data/oda/spreadsheet/ui/dataset

Let me know if you have any questions.

hope this helps

Hi,

you can restore everything that is part of your serialized model. When creating a ODA data source you can specify public and private properties. These properties are to be written to the rptdesign xml file. You can restore every single property of your ODA data source in the dialogs.

In my sample i had several properties to be restored (query text was only one of them). If you couldn't restore a certain property it would be very difficult to execute the data source (everything that you can't restore is lost and will not be written to your report design xml file).

If i understand correctly you have problems when the user edits a data set and switches from preview back to query to change the query and reruns preview. What's exactly your problem?

Hi Christian, 
 
Yes your correct. 
 
If i understand correctly you have problems when the user edits a data set and switches from preview back to query to change the query and reruns preview. 
 
As you said above, at this point i need to restore all the UI state. 
In my ODA, i didn't use any private or public properties.

Hi Christian,

As you said, i was trying to create properties using below code in savePage method,

private void savePage( DataSetDesign dataSetDesign )
{
if ( dataSetDesign.getPublicProperties( ) == null )
{
String dsID = dataSetDesign.getOdaExtensionDataSourceId( );
String dstID = dataSetDesign.getOdaExtensionDataSetId( );
Properties dsProp = DesignSessionUtil.createDataSetPublicProperties(
dsID,dstID,getBlankPageProperties( ) );
dataSetDesign.setPublicProperties( dsProp );
}
System.out.println("dataSetDesign.getPublicProperties()="+dataSetDesign.getPublicProperties());
}

But unfortunately to my surprise, Properties object i.e. dsProp always returns null, even after setting Public properties, above code for reference.

Please let me know your suggestions.

Thank You.

Sri Sai

Are you able to share your code or is this a commercial project?

Sorry Christian not possible.
Am using the method which i pasted above.
Please let me know, were you referring to the same properties object or some thing else.
