Image is not showing up on Dialog.

I am getting problem with Dialog. In my Dialog I have created the image field which accepts image from dam by Drag and drop. Whil Iam dropping the image it is showing up inside the Dialog properly and is showing up on the screen also But when I try to edit the image the current image got vanished inside the dialog. I don't understand why it is happening?

Here is the example of configuration of an image on the tab of dialog.

<backImage
jcr:primaryType="cq:Widget"
cropParameter="./backImage/imageCrop"
ddGroups="[media]"
fileNameParameter="./backImage/fileName"
fileReferenceParameter="./backImage/fileReference"
mapParameter="./backImage/imageMap"
name="./backImage/file"
requestSuffix="/backImage.img.png"
rotateParameter="./backImage/imageRotate"
sizeLimit="100"
title="Background Image"
xtype="html5smartimage"/>

You need to create a hidden property in order to be able to edit the image. Create a node below your image node and set a hidden property. You can refer :

/libs/foundation/components/textimage/dialog/items/tab3/items/resType
e.g.
<items jcr:primaryType="cq:WidgetCollection">
                    <resType
                        jcr:primaryType="cq:Widget"
                        ignoreData="{Boolean}true"
                        name="./sling:resourceType"
                        value="foundation/components/image"
                        xtype="hidden"/>
                </items>


Now the config of image will be:

<backImage
jcr:primaryType="cq:Widget"
cropParameter="./backImage/imageCrop"
ddGroups="[media]"
fileNameParameter="./backImage/fileName"
fileReferenceParameter="./backImage/fileReference"
mapParameter="./backImage/imageMap"
name="./backImage/file"
requestSuffix="/backImage.img.png"
rotateParameter="./backImage/imageRotate"
sizeLimit="100"
title="Background Image"
xtype="html5smartimage">
<items jcr:primaryType="cq:WidgetCollection">
<resType
jcr:primaryType="cq:Widget"
ignoreData="{Boolean}true"
name="./backImage/sling:resourceType"
value="foundation/components/image"
xtype="hidden"/>
</items>
</backImage>

How to add a new supported language in CQ / WEM (Translator in CQ)

Use case:  You want to add new language to CQ Change display language options in translator grid Change language name and default countries  Solution: You can access translator UI in CQ with following URL http://<HOST>:<PORT>/libs/cq/i18n/translator.html Create new language location for Dictionary Go to CRXDE lite (or your favorite JCR browser) and add this structure (assuming /apps/myapp/i18n as a typical location for custom apps): /apps/myapp/i18n [sling:Folder]     - de [nt:unstructured]         + jcr:mixinTypes = [mix:language]         + jcr:language = de     - fr [nt:unstructured]         + jcr:mixinTypes = [mix:language]         + jcr:language = fr Then reload the translator and the path /apps/ myapp /i18n should show up in the drop-down at the top. Note: the translator will only save translations for languages that are actually present underneath the path (e.g. /apps/myapp/i18n), others will be skipped. Then on jsp pa

Login / Logout on a Publish instance and Closed User Group (CUG)

In CQ5 there is the login logout could be configured using a Closed User Group. Closed User Groups (CUGs) are used to limit access to specific pages that reside within a published internet site. Such pages require the assigned members to login and provide security credentials. http://dev.day.com/docs/en/cq/5-4/howto/create_apply_cug.html The logout using /libs/cq/core/content/login.logout.html always gets redirected to the geometrixx site   http://localhost:4503/content/geometrixx-outdoors/en.html By configuring the Default login page  under the osgi configuration for com.day.cq.auth.impl.LoginSelectorHandler to be – /content/mysite/en/login But still after logout the page goes to the geometrixx site. IIRC, the redirect first goes to to / which then goes through the standard, somewhat complex handling of the root with multiple redirects: 1) / has a resource type of sling:redirect and redirects to /index.html 2) /index.html is handled by the RootMappingServlet [0] which h

This is used by all bundle-based Persistence Managers. The default size of BundleCache is 8 MB.
