Development -> Hotdeployment with HotSwapAgent -> Go to message
Thanks for figuring this out!!

It still didn't work...

But when I also added Log4j2 and JdkPlugin to the disabledPlugins in hotswap-agent.properties in tomcat/lib, it started working.

Looks great

Kind regards

Kind regards Wim
Development -> Checking page status during Selenium tests -> Go to message
That would be great!
Development -> Checking page status during Selenium tests -> Go to message
Hi Bjorn,
I refactored my tests like you said in this thread, and overall this worked good.
I wait until the counter is increased by 1 and then I continue. If the counter is not increased in 3 seconds, then I also go further.
The only disadvantage is that also a lot of actions does not increase the counter, so my test duration is now much longer. > 9 hours (coming from 2)
If you have some fine tune ideas? Can we know somehow which actions trigger the counter?

Kind regards
Wim

Deployment -> Environemnt JRE17.0.3_10 (OpenJDK) / Tomcat9.0.64 -> Go to message
Hi,

Downloaded this version and installed this. (under C:\EnterpriseClientRISC)

When I do C:\EnterpriseClientRISC\server\jre\bin\java.exe -version
I got:

openjdk version "11.0.15" 2022-04-19
OpenJDK Runtime Environment Temurin-11.0.15+10 (build 11.0.15+10)
OpenJDK 64-Bit Server VM Temurin-11.0.15+10 (build 11.0.15+10, mixed mode)

Looks like it is not version 17.
Can I put jre version 17 their by myself?

Kind regards
Wim


Development -> chartjs version -> Go to message

Development -> arraygrid set column width in percentages -> Go to message
Hello everyone,

I'm trying to set the column widths in an arraygrid in percentages without success.

When I create the arraygrid without width definition, every column have the same width, and the titles are readable.

When I create the arraygrid with absolute widths definition, the columns have the correct widths, and the titles are readable.

When I create the arraygrid with percentages widths in the definition, the columns have the correct widths, but the titles are not readable (only the first few pixels are present)

No persistid is set

Is it possible to use arraygrid with column widths in percentages?




Kind regards
Wim

Testcode
Code:
 		String[] titles = new String[4];
 		String[] widths = new String[4];
 	
 		titles[0] = "Aantal";
 		titles[1] = "Drank";
 		titles[2] = "EH-prijs";
 		titles[3] = "Totaal";
 
 		widths[0] = "15%";
 		widths[1] = "55%";
 		widths[2] = "15%";
 		widths[3] = "15%";
 
 		m_ticketgrid.setWidths(widths);
 		m_ticketgrid.setTitles(titles);

Is it possible to enable the blockerinfo without all these errors?

Anyone an idea what to do?
Development -> High memory usage in webbrowser -> Go to message
I made a small tinytask application that clicks around in my application (opening screens, switching tabs,...). When I do that for about 2 hours, I saw that my browser (chrome) takes 1.8GB of memory (only 1 tab), and the application became slower and slower.
On the server side everything runs fine.
Is there something I can do about this?

After contacting Bjorn, I updated to the latest version (see release notes about popups).

After that, I relaunch the test and everything runs fine now. After a 5 hour 'stress' test the browser-tab consumes now 317MB.

Start was 170MB
after 3 hours 310MB
after 5 hours 317MB (memory usage is stable)

Kind regards
Wim
