ListGrid Date Issue

[chris1978]

Hi,

Version: Power Edition 2.3 / 27.08.2010

In a datasource I have a field with the type “datetime”. In a ListGrid I want to show the format “DD.MM.YYYY”.

ListGridField logValidTo = new ListGridField(GeneratedFieldConsts.F_LOG_VALID_TO);
logValidTo.setDateFormatter(DateDisplayFormat.TOEUROPEANSHORTDATE);

Problem:
In the ListGrid ist the format “DD/MM/YYYY”. If I use the type “date” in the datasource the format is perfect out of the box (“DD.MM.YYYY”). Is there a simple way to change the date separator for a ListGridField?

Regards
Chris

You can set the default system-wide separator with DateUtil.setDefaultDateSeparator().

[nhuettner]

Thank's,

since which build is that function implemented? Rather which build is recommended?

I use the Power Edition 2.3.build.2010-08-27 and that function isn't covered.

Chris

Whoops, you are correct that it was missing. It has now been added and will appear in the next nightly, or you could add a method to call it via JSNI now:

    public static native void setDefaultDateSeparator(String separator) /*-{
        $wnd.isc.Date.setDefaultDateSeparator(separator);
    }-*/;

I tried nightly build 11.10.2010 of the Power Edition. During startup I got the following exception:

09:08:32.305 [ERROR] [frontend] Failed to create an instance of 'de.sdom.frontend.client.Frontend' via deferred binding

More information required?

[Isomorphic_Paul]

Sorry about that - a bug in the implementation.
This is now resolved - try the next nightly build (October 14 2010) and let us know if you continue to see problems

[chris1978]

I tried the current nightly (17. October) and got the following exception in every Form with a DateItem:

[Isomorphic_Paul]

We've tested this against the build you mention without seeing this problem.
Can you check for stale code (try running GWT Compile on your project, or possibly clearing your browser cache and see if you continue to see the bug).
If you do - post a test case

Thanks

[chris1978]

I narrowed down the problem. The exception occurs if I use the option "useMask=true". Without the option it's working fine.

package de.sdom.frontend.client.widgets;

import com.google.gwt.core.client.JavaScriptObject;
import com.smartgwt.client.types.DateDisplayFormat;
import com.smartgwt.client.widgets.form.fields.DateItem;

public class StyledDateItem extends DateItem {

	public StyledDateItem() {
		super();
		init();
	}

	public StyledDateItem(JavaScriptObject jsObj) {
		super(jsObj);
		init();
	}

	public StyledDateItem(String name) {
		super(name);
		init();
	}

	public StyledDateItem(String name, String title) {
		super(name, title);
		init();
	}

	private void init() {
		this.setUseTextField(true);
		this.setMaskDateSeparator(".");
		// this.setUseMask(true);
		this.setDateFormatter(DateDisplayFormat.TOEUROPEANSHORTDATE);
		this.setEnforceDate(true);
	}

}

[Isomorphic_Paul]

Ahh - ok I see it.
Thanks for the test case. This is now fixed (and tested). The fix will be present in the next nightly. Let us know if this still happens for you after tonight's build (will be dated Oct 20)
