Each UCOSP participant is asked to log all their accomplishments as well as the difficulties they have getting set up to understand Umple and other experiences they have. Difficulties might include understanding how to model in Umple, using UmpleOnline, code that is difficult to figure out, and development tools that are hard to figure out, or don't seem to work properly. The more log entries added the more we can better get a grip on the usability issues with Umple, and the more we can help future new contributors come up to speed.
Added Umple iPad App description in here
https://github.com/charlesmwang/Umple-iPad-App/wiki/Umple
Created a new issue for the iPad App (Issue 554 (on Google Code))
Added the ability to add new class to the diagram
Checked Issue 544 (on Google Code) and found out that the "use" keyword was crashing the parser.
iPad App
Improved "animation" performance of the association line.
The previous method was taking so much memory.
The new method significantly reduced the memory usage.
Made it integrate well with scroll view.
Worked on Umple iPad App
https://github.com/charlesmwang/Umple-iPad-App Tested that my fix in Issue 503 (on Google Code) resolved Issue 520 (on Google Code) and Issue 320 (on Google Code) .
Found out that the example listed in Issue 450 (on Google Code) worked.
Added an example that Issue 450 (on Google Code) would fail.
Worked on implementing the fix for Issue 503 (on Google Code) inside the cruise.umple src folder.
Modified the UmpleSync_Code.ump as well as other files. Added a functionality to parse umple code from string object, rather than file object. I first split the UmpleCode to main code and layout code. Used umple parser to extract class names in the main code. Stored the classes in a HashMap. Compared that with the layout code in the other function. Then I tested the code manually by executing java command - calling umplesync.jar from shell. It worked nicely. However, on UmpleOnline, the issue still existed. Then, checked the problem by printing each line in the umple code inside cruise.umple. Found out the json sent was invalid. Checked the json and saw the
URL_SPLIT was included (Issue 542 (on Google Code)). After removing it, everything worked nicely. Then checked to see that what would happen if I revert the files I modified in cruise.umple. Then, it still worked. Also, modified the umple_association.js file since it cause UmpleOnline to cause an infinite load time. Submitted a patch for Issue 503 (on Google Code).
ant -Dmyenv=local -f build/build.umple.xml umpleSelf compile packageMainJar packageJars
Fixed Issue 541 (on Google Code) and sent a patch.
Proceeded with a client-side fix for Issue 503 (on Google Code).
Tim sent a reply about the patch not working for example, accident. Tested my code with the accident example and it deleted the class. Tried to debug the problem by printing classes in the diagram and matching them with the umple code, but cannot find the problem.
Found the code location to insert my code. Performed test by creating a class, moving it, and renaming it. My code deleted the extra class automatically. Submitted patch.
Trying to use regex to extract classes in the umple code and compare that to the diagram view.
Made the fix temporarily using a keyboard shortcut (debugging).
Investigated UmpleSync_Code and Generator_CodeUmple to see if Issue 503 (on Google Code) is solvable.
Visited Europe for Spring Break.
Fixed bugs in previous implemented method, however if association is included, the umple online will freeze.
Investigated Issue 503 (on Google Code). Implemented a poor way to fix the issue by comparing the umple code and the layout code. Deleted the previous class name. The issue was that when renaming the class name, it did not rename the class name in the layout editor and the old class was not deleted.
Submitted Issue 527 (on Google Code) with some bug fixes
Submitted Patch for Issue 49 (on Google Code)
Worked on Issue 527 (on Google Code) and implemented restoring saved preferences
Implemented all keyboard shortcuts in Issue 49 (on Google Code)
Might considering making a separate javascript file just for keyboard shortcuts
Attempted to update the jQuery version as well as jQuery UI files one by one, but no success
CodeMirror needs to be updated as well
Investigated possible issues that togetherjs does not work with Umple
- jQuery version conflict
Umple Online does not support websocket
Error from console:
Uncaught TypeError: Object #<Object> has no method 'on'Implemented some shortcuts in Issue 49 (on Google Code) Shift+Arrow
Tested togetherjs for collaboration.
Cannot get it working right.
Investigated Issue 503 (on Google Code)
Created an issue that allows user to restore its previous umple online session.
Created a patch for Issue 515 (on Google Code).
The reason of the bug is described in the issue 515 (on Google Code) page.
Implemented and testing session restore using cookies.
In the cookie I am storing the filename as well as its expiration.
The umple online page will display a link next to the bookmark link.
Added a wiki page for debugging tools in web development.
https://code.google.com/p/umple/wiki/DebuggingInWebDevelopment Went through my semester plan with my Professor.
Creating session restore functionality using filestorage.
The data will be stored in client side.
Submitted Patch for Issue 49 (on Google Code) that includes new shortcuts and added shortcut help text next to the class, association, generalization, undo, and redo.
First thought it was a client side issue, but further investigated it and found that it was a server-side issue.
When we add a list or a comparator, the client calls editClass and editAssociation.
When the editAssociation is called, the umpleCode attached is blank.
However, I set breakpoint and found that the editClass returns a blank umple code.
I verified this by creating and editing/dragging the class and it returned a nonblank umple code.
Checked the compile.php and found the line that calls the editClass in UmpleSync.jar.
In the source file, the file is UmpleSync_Code.ump.
The section that is causing the disappearance I think is in editAction.
I think the UmpleSync.jar cannot read the attribute:type:list properly.
'c' - Add new class
'a' - Add new association
'g' - Add new generalization
'ctrl-z/cmd+z' - undo
'ctrl+y/cmd+shift+z' - redo
Using mousetrap to hand multikey shortcuts.
http://craig.is/killing/mice Testing the shortcuts.
Created a delete shortcut for Umple Online for Issue 49 (on Google Code)
Initially had trouble with it because when editing the model in the textfield, the model gets deleted.
Workaround of this issue was using jQuery to find elements in the nested tree for an input.
If input was not found, delete the class diagram.
Sent a patch and waiting for approval
Found a bug in Umple Online - Issue 515 (on Google Code)
Investigated Issue 204 (on Google Code)
Now can drag class diagram for touchscreen device.
Problem is that it can only drag the newest generated class model.
Will work on improving this one.
For the touch, I am using hammer.js
Investigated Issue 49 (on Google Code)
