There were some problems with the getRecords() API reported and fixes early on. Try that latest nightly or build from SVN.

**pascalpug** · 22 Jan 2009, 19:58

I get this error with revision 252. Will try later SVN...
Using a workaround:

Code:

int size = grid.getTotalRows();
ListGridRecord record = null;
for (int i = 0; i < size; i++) {
	record = grid.getRecord(i);
	...
}

thanks Isomorphic!

Are you using a ListGrid or a TreeGrid? I tried calling ListGrid.getRecords on one of the Showcase grid samples and it worked fine. Can you post a standalone test?

Thanks,
Sanjiv

getRecords() does not appear to work with the TreeGrid. Returns empty list. Using nightly build from Jan 23.

im experiencing the same problem with 1.1

I have a ListGrid and every time a make a call to getRecords() the same exception occours.

the funny thing is when i do not attach the widget to a container everything works fine; once it gets attached the exception occours

i'm going to test the workaround proposed by pascalpug

Code:

com.google.gwt.dev.shell.HostedModeException:
Expected primitive type int; actual value was undefined
    at com.google.gwt.dev.shell.JsValueGlue.get(JsValueGlue.java:51)
    at com.google.gwt.dev.shell.ModuleSpace.invokeNativeInt(ModuleSpace.java:209)

    at com.smartgwt.client.widgets.grid.ListGrid.getRecords(ListGrid.java:4942)
    at ... < CUT >

-----
edit:
i just tested the workaround:
well the exeption is gone, but it seems i have a deeper problem

when the grid is visible:
afer an addData operation the grid reports ( with the workaround method ) that it is emty

when the grid was not yet drawn:
after an addData operation the grid reports the inserted entry

any ideas?

Can you post a standalone test case, or a modification to an existing showcase sample that illustrates the problem?

i tracked down my problem to the grouping function
the above described problem only occours when grouping is enabled

is it intended that some Record related methods ( addData, getRecords, .. ) change their behavior when you enable grouping?

**chrisem** · 9 Jul 2009, 05:34

I believe that once you group a ListGrid the internal structure gets converted to a TreeGrid and you no longer have access to the original data that you entered into the listgrid.

In order to get records out once grouped I just ungroup, getRecords and then group again to work around it - not ideal but it works.

**smartgwt.dev** · 9 Jul 2009, 07:13

We've added a ListGrid.getGroupTree() to return the underlying Tree datastructure when the ListGrid is grouped on a field.

Edit : getRecords() will now work even when the ListGrid is grouped.

Once you have the Tree data structure, you can navigate the Tree using the appropriate API's.

getting error with trunk

Hi, I built smartgwt1.1 from the trunk (first-timer :)) and re-ran my code, but still get the errro 'Expected primitive type int; actual value was undefined' on getRecords():
I thought this would be the fixed source, but doesn't look like it. Is there another repository for updated code that I should build from?
UPdate: I just ran with the latest revision (http://smartgwt.build.rorschach.de/revision.618/) but am still seeing the same thing.

Code:

		ListGridRecord[] nodes = services.getRecords();

The error seems to occur here, in JavaScriptHost.class:

Code:

int com.google.gwt.dev.shell.ShellJavaScriptHost.invokeNativeInt(String name, Object jthis, Class<?>[] types, Object[] args) throws Throwable

Code:

 /**
   * Invoke a native JavaScript function that returns an integer value.
   */
  public static int invokeNativeInt(String name, Object jthis,
      Class<?>[] types, Object[] args) throws Throwable {
    return sHost.invokeNativeInt(name, jthis, types, args);
  }

Stacktrace

Error: Expected primitive type int - example attached

I'm still having the issue with "Expected primitive type int; actual value was undefined" even though I'm using the latest revision (618) of smartgwt.

Please note, I cannot use the workaround suggested by pascalpug, because the value I get for getTotalRows is always 1000

Code:

	int size = this.getTotalRows();
	system.out.println("total rows = " + size);

        total rows = 1000

However, I can workaround that using:

Code:

		int size = services.getTotalRows();
		ListGridRecord record = null;
		boolean stop = false;
		for (int i = 0; i < size | stop; i++) {
			record = services.getRecord(i);
			if (record == null)
				stop = true;
			System.out.println("size = " + i);
		}
		
		System.out.println("services.size = " + size);

Still I like to get to the bottom of why ListGrid.getRecords() isn't working for me.

I've attached a complete example; this post contains 5/9 files, see next post for remaining 4 files.

Thanks,
Dave

ListGrid.getRecords not working for me - example provided

Would someone tell me if they are seeing the same thing as I am?
Several posts back it was reported that getRecords is working ... what am I doing wrong?

Thanks,
Dave

**ddumaresq** · 20 Jul 2009, 07:19

Odd ... works after first run

I'm testing this in hosted mode and notice that after the first error

Code:

com.google.gwt.dev.shell.HostedModeException: 
Expected primitive type int; actual value was undefined),

I can refresh the development shell and the problem goes away... Unfortunately, this is not the case when I choose Compile/Browse and the app runs inside FireFox.
