system calendar image background color

[xren]

Hi,

How to set the background color for the system calendar image? It is transparent now.

Thanks,
Xiaoli

Xiaoli,

It's just a gif image file - in webapps/ufs/shared/images/calendar.gif. We don't let you use an image from another location so your only option is to replace the existing one with something else.

Hi Jon,

It is not this image. What I would like to change is the big one when you click this small image then the real calendar opens with year, month, days and you pick. That is transparent. It is hard to see the date when it is over other fields.

My system doesn't have this problem. The calendar popup has a white background but it's not transparent and I can't see fields through it. Which Ebase version are you using and which browser? Does it do this with all browsers?

[xren]

It is ebase 4.5.3.

My browser is Google Chrome.

Xiaoli,

I don't know why you have this problem. I don't see it with Chrome and Ebase 4.5.3. You might check if you get it with all forms or just one specific form, and if you get it with other browsers. You could try refreshing the page in Chrome with Ctrl-R in case you have something strange cached, or you could try clearing the Chrome browser cache. The calendar popup is built by JS file calendar453.js, but I don't think it's a good idea to try changing this.

Hi Jon,

I tried other browser. It is the same. Fresh doesn't work. It the same on other forms.

I wonder if the css for the image is not included. Do you know anything about this?

Could you send a screen shot of the problem to support@ebasetech.com. I don't think there is any externall css for the calendar - it's all contained within the javascript which builds HTML for the popup dynamically. The popup isn't an image.

Hi Jon,

I have sent the screen shot.

Hi Jon,

It is just happens to this form.
I also sent you the form and associated script for this form.

Can you take a look?

please let me know if you need more information.

Thanks,
Xiaoli

Xiaoli,

I suspect that you have something in one of the style sheets which is interfering with the calendar. I had a look at your form, but it didn't help much as all the style sheets are missing - they are in the shared directory on the server. You could check these style sheets for anything suspicious or you could try removing them one by one to see if the problem goes away.

Are you familar with debugging your browser using Firebug? This could make debugging this issue much easier - you can use this to check the CSS which is being applied to the calendar and see which CSS file it's come from.

Hi Jon,

It was related to CSS. There is one setting background as transparent in one of the css files.

It shows correctly now. Thank you.
However, eventually, I would like to use jquery, which doesn't work for this form (but ok on other forms) now. Can you check the form and script what can be the reason?

The other thing I would like to ask your help is that can you check this form and scripts see what can cause memory leak/high usage, etc.?
My system often report outofmemory PERMGEM error.

Thanks,
Xiaoli

Xiaoli,

It's most unlikely that anything in your form will cause a permgen error. We have had lots of problems with permgen errors - you will see plenty of logs in this forum. The parameters that matter should look like this:

-XX:PermSize=256m
-XX:MaxPermSize=512m

Note that we have previously told you to use -Dxx, which is wrong, for these parameters. The reason you are having problems is almost certainly because these parameters are not configured correctly.

Sorry for any confusion.

Regards
Jon

Hi Jon,

Is the following exception related to permgen space well or it leads to permgen space exception?

Possibly yes, this exception is in the area where we see permgen problems. But I would expect to also see an OutOfMemoryError if it is a permgen problem.
