Open SQLEditor programmatically causes NPE [message #590956] Sat, 12 April 2008 12:47 Go to next message

Hi,

I am trying to open programmatically the SQLEditor after generating some SQL
Code. What I try to do exactly is:

----------------------------------------
SQLEditorStorage output = new SQLEditorStorage(mySQLCode.toString());
IWorkbenchPage page =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage();

SQLEditorStorageEditorInput input = new SQLEditorStorageEditorInput(output);

//this works and opens the default text editor
//page.openEditor(input, "org.eclipse.ui.DefaultTextEditor");

//this doesn't work
page.openEditor(input, "org.eclipse.datatools.sqltools.sqleditor.SQLEditor");
----------------------------------------

It works with the DefaultTextEditor and I can also open .sql-Files with the
SQLEditor by Hand.

With the version above I get a java.lang.NullPointerException

For me it seems that there is a problem with
SQLDevToolsConfiguration toolsConfig =
SQLToolsFacade.getConfigurationByVendorIdentifier(getConnect ionInfo().getDatabaseVendorDefinitionId());

Does anyone know how I can wrap around that? Or is it possible to give the
missing information with the SQLEditorStorageEditorInput Object. I can't
find anything.

By the way I tried DTP 1.5.2 and 1.6.

Thanks,

Martin Baus

Refer the code in OpenScrapbookAction from package org.eclipse.datatools.sqltools.sqlscrapbook.actions

This resolved the above issue for me :
ISQLEditorConnectionInfo editorConnectionInfo = SQLFileUtil.getDefaultConnectionInfo();

String scrap = "";
SQLEditorStorageEditorInput editorStorageEditorInput = new SQLEditorStorageEditorInput(
"", scrap);

editorStorageEditorInput.setConnectionInfo(SQLFileUtil.getConnectionInfo4Scrapbook(editorConnectionInfo));

// the name will show as the title of the editor
IEditorReference[] editors = window.getActivePage()
.getEditorReferences();
int suffix = 0;
List editorNameList = new ArrayList();
for (int i = 0; i < editors.length; i++) {
editorNameList.add(editors[i].getName());
}

for (;;) {
String name = NLS.bind(
Messages.OpenScrapbookAction_scrapbook_title, Integer
.toString(suffix));
if (!editorNameList.contains(name)) {
editorStorageEditorInput.setName(name);
try {
window.getActivePage().openEditor(editorStorageEditorInput,
SQLScrapbookEditor.EDITOR_ID);
} catch (PartInitException e) {
SqlscrapbookPlugin.log(e);
}
break;
}
suffix++;
}
