JD12 JSF designer does not redraw

Question

I am having many issues in JD12 JSF designer.
One is that when I for example select a navigation button's spacer and change it's Width property, the space between buttons does not change until file is closed and re-opened. Is that expected behaviour? Dropping an operation onto the navigation button is very tricky as well. Even when selected is 'Panel group layout', sometimes a rebinding window comes up. The space where a button has to be dropped is so narrow and volatile, that dropping a button becomes a torture that I have to repeat 2-3 times before it actually drops exactly one button (and does not rebind or drop 3 copies of it).
Another is that when I am changing table column Sortable and Filterable properties, they take 2 times to change the selected values from default to true or vice versa. The green dot does appear in front of property name, but drop down reverts to default (or previous value whatever it was). Suppose I changed Sortable from default to true - it did not change. Then I am changing Filterable in the sam manner and it does not redraw, but Sortable now does. Then I have to change sortable to the same new value again and Filterable now changes. Very annoying. Is there a fix?
Selecting the controls is bugged as well.  Suppose I selected a table column and changed its Row header property to true, then went on to change another one. When I click another column, it does not select, but a baloon pops up which contains a binding for that column. To close it I have to click elsewhere and re-click the column again. Why is that happening?
Suppose I dropped a panel border layout onto a facet. Undoing that does not visually remove the border layout from a form. Only closing a file and re-opening will re-draw. Similarly, I am adding a navigation button from Operations, but the buttons do not re-draw to show that a new button was added. Same as previous, only closing/re-opening a file shows a new button. Royal PITA. Is there a fix?
Suppose I am changing initial size of a table. The number by the right corner changes showing the new size, but after the bottom border is released, the size does not re-draw. Only closing and re-opening a file shows the new size.
Resizing table columns is painful. When a column is shrinking, the columns to the right of it do not move accordingly - they stay put and the width of the very next column is increasing. Thus it is absolutely impossible to arrange the columns that are beyond visible width of the table. When the column is growing, the columns to the right of it behave erratically - often they suddenly increase their width and disappear beyond the right table border. This is simply infuriating.
The last is that if the data controls dropped onto the page contain columns from more than one table, then resulting application will throw runtime exceptions (null pointer). But if I deleted all columns but that very object's own columns, and dropped it onto the page, then it will work. After that I can add any columns from that object and it will work fine. The Create Table wizard clearly creates defective code.
I am running JDEVADF_12.1.2.0.0_GENERIC_130608.2330.6668 under Windows 7 32bit. Are these issues fixed in a more recent build or going to be fixed soon?

Answer 1

You are not understanding the term 'narrow space' I've used. It does not equal 'width of spacer between the buttons. It equals the area of display monitor where an orange drop indicator appears that supports dropping a new button in between the existing ones. I.e. where JD12 is allowing me to drop a new operation without rebinding the existing buttons.
The JDK version is the one that JD12 itself installed - 1.7.0_15. As that's the JDK that was shipped with JD12, I contend it has to be sufficient.
There is no Mcaffee on this machine. They are using Symantec AV. There is about 300-500 MB free RAM when these issues are occurring and CPU load is about 0%.
Another issue I just noticed is that javadocs are not loading. Doc Path for JDK 1.7.0_15 that came with JD12 is set to http://docs.oracle.com/javase7docs/api/ and there is no doc under the folder where JD installed its JDK. I don't know how to fish docs for an older JDK out of Oracle web site.
As you contend that it is my system that is a root cause, I looked up the system requirements for JD12 and found that my system exceeds them.
