I wrote server in C and client in Java. I used JavaFX for GUI. Everything works except that sometimes I get exceptions when textArea gets filled and receives more data before it gets reseted (probably cause of parallel threading). Actually there are 3 cases which occur "randomly":
1) Stucks/hangs and no exceptions are thrown.
2) NullPointerException (about Line Padding and Content Bounds [there's nowhere my code mentioned]).
3) IllegalArgumentException: Both width and height must be >= 0.
4) Exception about String text bounds.
Here's the code if it helps:
if(textArea.getLength() > 500) // I tried with > 2000, similar situations occur
textArea.setText("");
command = textField.getText();
out.println(command); // out to socket
textField.setText("");
Btw, this GUI should represent basic Linux shell, so textArea should sometimes be able to receive large amount of data (such as netstat command).
Thanks!
It is an exact dublicate of your previous question but with more info, so not going to vote for closing. I asked you to post exception stacktrace in that previous question, but you mentioned there is no your code related lines in stacktrace, hence I also presume like you that it is a bug of textArea. So I suggest to try to use another component, for example a big Label with white background :), if it is solely for displaying purposes.

I'm trying to print some RFID tags and retrieve their TIDs to store them in my system and know which tags have been printed. Right now I'm reading the TID and sending it back to my computer (connected via USB with the my ZT421 printer) with the following code:
^RFR,H,0,12,2^FN0^FS^FH_^HV0,24,,_0D_0A,L^FS
^RFW,H,2,12,1^FD17171999ABABABAAAAAAAAAB^FS
This is repeated for each tag that I'm printing. However, when printing 10 tags, I only get 9 TIDs. If after that I try to print 7 tags, I still get 9 TIDs. To be honest I'm a bit lost now, because even trying to use the code examples from the ZPL manual (I've tried the ^RI instruction also) it doesn't seem to work.
The communication with the printer is beeing done through Zebra Setup Utilities' direct communication tool.
I tried to retrieve each printed tag TID with:
^RFR,H,0,12,2^FN0^FS^FH_^HV0,24,,_0D_0A,L^FS
^RFW,H,2,12,1^FD17171999ABABABAAAAAAAAAB^FS
but I always get 9 TIDs.
I also tried getting the TID with the ZPL manual example for the ^RI command:
^XA
^FO20,120^A0N,60^FN0^FS
^RI0,,5^FS
^HV0,,Tag ID:^FS
^XZ
And I got absolutely nothing returned to the computer, just a mssage saying "Tag ID:" and no value shown.
I would really appreciate some help with this...
Thanks in advance!
I've fixed the issue, but I'm going to leave the solution here just in case someone else is facing the same problem.
I thought that maybe it wasn't a code issue, but something related to the computer-printer communication. It turned out to be the case. The Zebra Setup Utilities program has a button that says "options". If you click it, a new screen will open and there you can configure the seconds that the program will wait for the printer response (in this case through USB). By default it's set to 5, i changed this value to 100, which is the maximum. This meant that instead of just printing and retrieving the TIDs of 6-9 tags, now I can do it for about 100.
This is not amazing because in my case it implied creating 25 files for the 2500 tags I had to print and store the TIDs, however it's far better than before.
Currently, I made a tool to rename view numbers (“Detail Number”) on a sheet based on their location on the sheet. Where this is breaking is the transactions. Im trying to do two transactions sequentially in Revit Python Shell. I also did this originally in dynamo, and that had a similar fail , so I know its something to do with transactions.
Transaction #1: Add a suffix (“-x”) to each detail number to ensure the new numbers won’t conflict (1 will be 1-x, 4 will be 4-x, etc)
Transaction #2: Change detail numbers with calculated new number based on viewport location (1-x will be 3, 4-x will be 2, etc)

Py File here: http://pastebin.com/7PyWA0gV
Attached is the python file, but essentially what im trying to do is:
# <---- Make unique numbers
t = Transaction(doc, 'Rename Detail Numbers')
t.Start()
for i, viewport in enumerate(viewports):
setParam(viewport, "Detail Number",getParam(viewport,"Detail Number")+"x")
t.Commit()
# <---- Do the thang
t2 = Transaction(doc, 'Rename Detail Numbers')
t2.Start()
for i, viewport in enumerate(viewports):
setParam(viewport, "Detail Number",detailViewNumberData[i])
t2.Commit()
Attached is py file
As I explained in my answer to your comment in the Revit API discussion forum, the behaviour you describe may well be caused by a need to regenerate between the transactions. The first modification does something, and the model needs to be regenerated before the modifications take full effect and are reflected in the parameter values that you query in the second transaction. You are accessing stale data. The Building Coder provides all the nitty gritty details and numerous examples on the need to regenerate.
Summary of this entire thread including both problems addressed:
http://thebuildingcoder.typepad.com/blog/2016/12/need-for-regen-and-parameter-display-name-confusion.html
So this issue actually had nothing to do with transactions or doc regeneration. I discovered (with some help :) ), that the problem lied in how I was setting/getting the parameter. "Detail Number", like a lot of parameters, has duplicate versions that share the same descriptive param Name in a viewport element.
Apparently the reason for this might be legacy issues, though im not sure. Thus, when I was trying to get/set detail number, it was somehow grabbing the incorrect read-only parameter occasionally, one that is called "VIEWER_DETAIL_NUMBER" as its builtIn Enumeration. The correct one is called "VIEWPORT_DETAIL_NUMBER". This was happening because I was trying to get the param just by passing the descriptive param name "Detail Number".Revising how i get/set parameters via builtIn enum resolved this issue. See images below.

I am creating a game in HaxeFlixel, using flixel-ui to deal with the user interface. I have run into a problem using the FlxUI9SliceSprite. I have the following line of code to construct it:
_bg = new FlxUI9SliceSprite(0, 0, "assets/images/panel_bg.png", new Rectangle(0, 0, 280, 50), [8, 8, 16, 16]);
However, this does not work. I believe the problem is with the Graphic parameter "assets/images/panel_bg.png", as using null (which causes it to use a default graphic) works just fine.
When putting a try-catch around it, I got the following error message:
ArgumentError: Error #2015
I'm the maintainer of the flixel-UI library. The error you're experiencing is "Invalid Bitmap Data", which could be caused by any number of things. There's two possibilities that come to mind:
1) Your asset path is wrong, or your asset isn't being found for some reason.
2) Your asset is being loaded, but the 9-slice rules you're submitting result in it doing an "illegal" transformation that results in pieces of it being invalid Bitmap Data (like, say, a section where the math works out that the width or height of the piece is 0 or negative)
Number 1 is unlikely as that would probably just default to a null bitmap and it would just fall back to the default asset.
The easiest way to resolve this is if you could post a sample of the image asset you're using and link to it, then I could inspect what the 9-slice logic you supplied would do to it and narrow down your issue.
As the title says, the height of my tabs is not increasing as it should, my code looks like this:
JTabbedPane jtp = new JTabbedPane();
JLabel iconInTab = new JLabel(new ImageIcon("myImage.png"));
iconInTab.setPreferredSize(new Dimension(100,80)); // is the size of my Image, I've also try to do this using getSize
jtp.addTab(null,new JPanel());
jtp.setTabComponentAt(0,iconInTab);
I've also try this using html but it did not work either:
jtp.addTab("<html><p><p><p></html>",new ImageIcon("myImage.png"),new JPanel());
with the first code the problem is not the change of the size horizontally (the width change correctly), the problem is only on the height, with the second code, if I add multiple lines inside the html code, the text appear incomplete (just show the middle line) (also the width behaves as expected, the problem is the height). . .
why is this happening? or how could I get this done?
Note: S.O.: Mac OS X 10.8.1
Solved!!! The problem was that the default UI over MAC OS X (com.apple.laf.AquaTabbedPaneContrastUI), you only need to change it to the basicTabbedPaneUI (or the one of your preference), in my particular case I need to extend this class (it was a pain in the *, because what I wanted was really complex) to get the look & feel that I was expecting, if you have the same trouble just do this before adding your tabs:
myTabbedPane.setUI(new BasicTabbedPaneUI());
Note: Checking the default UI of your TabbedPane, may solve many different problems.
I am using Cucumber with RubyMine, and I have a scenario with steps that verify some special controls from a form (I am using cucumber for automation testing). The controls don't have anything to do with each other, and there is no reason for the steps to be skipped if one in front of them fails.
Does anyone know what configurations or commands should I use to run all the steps in a scenario even if they all fail?
I think the only way to achieve desired behavior (which is quite uncommon) is to define custom steps and catch exceptions in it yourself. According to cucumber wiki step is failed if it raises an error. Almost all default steps raise error if they can't find or interact with an element on the page. If you'll catch this exceptions the step will be marked as passed, but in rescue you can provide custom output. Also I recommend you to carefully define exceptions you want to catch, I think if you're Ok if selenium can't find an element on the page rescue only from ElementNotFound exceptions, don't catch all exceptions.
I've seen a lot of threads on the Web about people wanting to continue steps execution if one failed.
I've discussed with Cucumber developers: they think this is a bad idea: https://groups.google.com/forum/#!topic/cukes/xTqSyR1qvSc
Many times, scenarios can be reworked to avoid this need: scenarios must be split into several smaller and independent scenarios, or several checks can be aggregated into one, providing a more human scenario and a less script-like scenario.
But if you REALLY need this feature, like our project do, we've done a fork of Cucumber-JVM.
This fork let you annotate steps so that when they fail with a determined exception, they will let let next steps execute anyway (and the step itself is marked as failed).
The fork is available here:
https://github.com/slaout/cucumber-jvm/tree/continue-next-steps-for-exceptions-1.2.4
It's published on the OSSRH Maven repository.
See the README.md for usage, explanation screenshot and Maven dependency.
It's only available for the Java language, tough: any help is welcome to adapt the code to Ruby, for instance. I don't think it will be a lot of work.
The question is old, but hopefully this will be helpful. What I'm doing feels kind of "wrong", but it works. In your web steps, if you want to keep going, you have to catch exceptions. I'm doing that primarily to add helpful failure messages. I'm checking a table full of values that are identified in Cucumber with a table having a bunch of rows like:
Then my result should be:
| Row Identifier | Column Identifier | Subcolum Identifier | $1,247.50 |
where the identifiers make sense in the application domain, and name a specific cell in the results table in a human-friendly way. I have helpers that convert the human identifiers to DOM IDs, which are used to first check whether the row I'm looking for exists at all, then look for the specific value in a cell in that row. The default failure message for a missing row is clear enough for me (expected to find css "tr#my_specific_dom_id" but there were no matches). But the failure message for checking specific text in a cell is completely unhelpful. So I made a step that catches the exception and uses the Cucumber step info and some element searching to get a good failure message:
Then /^my application domain results should be:$/ do |table|
table.rows.each do |row|
row_id = dom_id_for(row[0])
cell_id = dom_id_for(row[0], row[1], row[2])
page.should have_css "tr##{row_id}"
begin
page.should have_xpath("//td[#id='#{cell_id}'][text()=\"#{row[3].strip.lstrip}\"]")
rescue Capybara::ExpectationNotMet => exception
# find returns a Capybara::Element, native returns a Selenium::WebDriver::Element
contents = find(:xpath, "//td[#id='#{cell_id}']").native.text
puts "Expected #{ row[3] } for #{ row[0,2].join(' ') } but found #{ contents } instead."
#step_failures_were_rescued = true
end
end
end
Then I define a hook in features/support/hooks.rb like:
After do |scenario|
unless scenario.failed?
raise Capybara::ExpectationNotMet if #step_failures_were_rescued
end
end
This makes the overall scenario fail, but it masks the step failure from Cucumber, so all the step results are green, including the ones that aren't right. You have to see the scenario failure, then look back at the messages to see what failed. This seems kind of "bad" to me, but it works. It's WAY more convenient in my case to get the expected and found values listed in a domain-friendly context for the whole table I'm checking, rather than to get a message like "I looked for "$123.45" but I couldn't find it." There might be a better way to do this using the Capybara "within" method. This is the best I've come up with so far though.
