A new component AREASELECTOR is available – with the main purpose of being able to crop images.
The component allows the user to select a certain area (e.g. on top of an image) and then passes the corresponding coordinates back to the application processing so that the image can be easily taken out of the original image using simple utility functions.
The component is not bound to image processing but can do any type of area selection on top of any components.
Some update in the area of focus management (“tab order”):
The tab order can now be explicitly defined using a new attribute FOCUSSEQUENCE.
The definition is done in some clever way and does not require to define tab number throughout all controls of the dialog – just the ones that behave different from the normal tab sequence need to be taken care off.
And: you now can define hot keys (keyboard shortcuts) behind components to directly move the focus into the component from where ever you currently are within a dialog. Use attribute REQUESTFOCUSHOTKEY accordingly.
Dear Community,

Please take a look into our new demo that shows a simple mobile application:
Please open from your mobile device >HERE<.
It uses components like:

Take a look into the article that was published in the German “Informatik Aktuell” online magazine:

The component is part of our component portfolio for quite some time – but we see that it is rarely used… So we want to push the visibility a bit. Here is a short video “from the labs”:
CaptainCasa logs quite useful information – e.g. problems when accessing expressions, performance data about each single request processing – and of course details about errors.
By default the logging is done in the following directory:
<installationDir>/server/tomcat/work/Catalina/localhost/<webApp>/log_eclntjsfserver.txt.*
There maybe several log files (there are 5 rotating files into which the log is written), so sort the directory by date and pick the newest one.
The logging is configured in the file:
<project>/webcontent/eclntjsfserver/config/logging.xml
Please refer to the logging.xml_template file within the corresponding /webcontentcc-directory of your project.
During development it makes sense to use log level “INFO” and to directly output the log to the console, so that you can directly observe what happens. The log configuration to do so is:
<logging level="INFO" console="true"> </logging>
Using log level “INFO” means that each request is logged. In the log you see the processing in different phases. A really useful information is the list of the include-structure of the current dialog. Here you can find out, which layout definitions (.jsp definitions) are used, and how they are nested.
There are a plenty of other configuration parameters that can be used in the logging.xml configuration, each of them being described in the logging.xml_template file. Examples:
We added a tool “Style Editor” to our set of tools. The tool simplifies the creation and editing of own style sheets.
In the tool you create you own style classes based on default classes. You always see the attributes of the default definitions and can easily override.
For one control you may define several style variants that are easily pick-able when designing a dialog.
A short video “from the labs” shows how to use the tool for editing own style classes:
We introduced an new style – and started to publish the new style within the demo workplace. The new style will be positioned as default style for new projects.
The new style’s name is “defaultlightbluerisc”. All existing styles are still valid of course. For viewing the full demo workplace click >HERE<.
The yearly Community Meeting is approaching! This year’s date is: Thursday, Dec 07th 2017
