Can you get a dev console snapshot (like your others) where the replacement widget is shown? If the log you mention is correct, it should have been removed to make way for another of the same name.

I have enough images to upload that I need to do this in multiple parts.

I have attached to this message three images that show the AskValueFormDialog before I click the upload button that is on that form. (the watch window spread across three images)

The interesting part of this is the Part1 image that shows the label isc_AskValueFormDialog_0_headerLabelParent_label object.

[sderouchie]

The 4 images attached to this message are from the watch Window after I click upload and the PleaseWaitDialog appears.

The interesting parts of this are:

1. the Part1 image where it no longer has a isc_AskValueFormDialog_0_headerLabelParent_label under the headerLabelParent canvas.

2. the PleaseWaitDialog_After_Click_Upload image where it shows the isc_AskValueFormDialog_0_headerLabelParent_label is now under isc_VLayout_16.

[sderouchie]

Any new updates on this issue?

We've been investigating this issue on our end but we are still unable to reproduce the problem. It seems you have some kind of configuration in place within your app which is a required condition for making the bug occur, and without a way to reproduce the problem (or a clear picture of the code path that leads to the bad state) there's not much we can do.

We'll continue to look but at this stage we probably just need to see a way to reproduce this -- in other words, a test case we can run on our end that causes the problem.

Please run your app in SuperDevMode, and set a breakpoint in com.smartgwt.client.core.BaseClass in the method

protected void error(String attribute, String value, boolean allowPostCreate) throws IllegalStateException {
        if (allowPostCreate) {
            error("Cannot change configuration property '" + attribute + "' to " + value + " after the component has been rendered.");
        } else {
            error("Cannot change configuration property '" + attribute + "' to " + value + " after the component has been created.");
        }
    }

at the line that raises the error "Cannot change configuration property after the component has been created."

Once the breakpoint is hit in your app, please capture the call stack and the relevant variables and post it here.

I've tracked it down that I can now provide a sample to help you debug the issue. It occurs when the application sets default canvas properties (which we do in our app). Here is some sample code (I used HibernateDS as a base for the sample)

The main class:

					}
				}
				);
        
		this.winModal.show();

}

The test window class which is used to simply cause the winModal dialog to pick up its discarded ID:

package com.smartgwt.sample.client;

import com.smartgwt.client.widgets.Window;

public class MyTestWindow extends Window {

	public MyTestWindow() {
		super();
	}
}

The test popup dialog. When the OK button is pressed on the winModal dialog in the main class, the label on this dialog ends up reusing the label header from the modal dialog:

package com.smartgwt.sample.client;

import com.smartgwt.client.types.Alignment;
import com.smartgwt.client.widgets.Button;
import com.smartgwt.client.widgets.Dialog;
import com.smartgwt.client.widgets.Label;
import com.smartgwt.client.widgets.events.ClickEvent;
import com.smartgwt.client.widgets.events.ClickHandler;
import com.smartgwt.client.widgets.layout.VLayout;


public class MyPopupTestWithLabel extends Dialog {

	public MyPopupTestWithLabel( final String title ) {
		this.setWidth( 260 );
		this.setHeight( 130 );
		this.setTitle( title );
		this.setIsModal( true );
		this.setShowModalMask( true );
		final Button cancelButton = new Button( "Cancel" );
		this.setToolbarButtons( cancelButton );
		cancelButton.addClickHandler( new ClickHandler() {

			@Override
			public void onClick( final ClickEvent event ) {
				MyPopupTestWithLabel.this.cancelClick();
				MyPopupTestWithLabel.this.destroy();
			}
		} );
		final VLayout body = new VLayout();
		body.setAlign( Alignment.CENTER );
		final Label theLabel = new Label( "the label" );
		theLabel.setAlign( Alignment.CENTER );
		theLabel.setHeight( "*" );
		body.setMembers( theLabel );
		this.addItem( body );
		this.setShowCloseButton( false );
	}

	/*
	 * (non-Javadoc)
	 * @see com.smartgwt.client.widgets.Dialog#cancelClick()
	 */
	@Override
	public void cancelClick() {
		super.cancelClick();
		destroy();
	}
}

If the following code is removed from the main class, then the problem goes away:

Canvas canvasProperties = new Canvas();
    	canvasProperties.setAlign(Alignment.RIGHT);
    	Canvas.setDefaultProperties( canvasProperties );

Please run your app in SuperDevMode, and set a breakpoint in com.smartgwt.client.core.BaseClass in the method

protected void error(String attribute, String value, boolean allowPostCreate) throws IllegalStateException {
        if (allowPostCreate) {
            error("Cannot change configuration property '" + attribute + "' to " + value + " after the component has been rendered.");
        } else {
            error("Cannot change configuration property '" + attribute + "' to " + value + " after the component has been created.");
        }
    }

at the line that raises the error "Cannot change configuration property after the component has been created."

Once the breakpoint is hit in your app, please capture the call stack and the relevant variables and post it here.

Now that I have a sample, do you still need this?

[Isomorphic]

We will take a look at the attached sample and let you know what we find. Assuming we can reproduce it we shouldn't need the additional debugging info from you

Thanks
Isomorphic Software

[sderouchie]

Are there any updates on this? Were you able to get the sample working?

[Isomorphic]

This should now be resolved. The change actually went in a couple of days ago and we failed to follow up on the thread.
Please try the latest nightly build and let us know if you're still able to reproduce the problem

Thanks
Isomorphic Software

[sderouchie]

Thank you! I have confirmed that the issue has been resolved.

[ahmed.labib]

i have faced that error but i can't find a solution for it till now would any one please tell me how to solve it

[sderouchie]

I haven't seen this issue since it was fixed in 2013.
Are you sure it's the same issue? There are some items you cannot change after the component has been created. Check the order in which your code is doing things.
