Servoy 2.2rc3

Version R2 2.2rc3-build 321
Java version 1.4.2_06-b03 (Windows XP)

Error message: application.closeFormDialog() triggers java.lang.NullPointerException (SaveCloseForm, line 3)

Have a global method - SaveCloseForm - with just two lines that is triggered by Save & Close button on number of popup dialogs called with application.showFormInDialog:

currentcontroller.saveData();
application.closeFormDialog();

During testing with rc2 the error message started showing. Tried rebuilding Form and problem disapeared for time then came back, deleted all records & reset PK's - again was fine for a few times then started failing again. Switched on Debugger (with no break points) and problem went away until debugger switched off.

Upgraded to rc3 but still have problem.

Does anyone have any clues ??

Thanks

Error message: application.closeFormDialog() triggers java.lang.NullPointerException (SaveCloseForm, line 3)

Further testing after computer reboot.

If I add/delete/change text or dates on the Dialog Form it saves/closes fine. If I just look at form and make no changes - always get error message.

Hope this helps

[jcompagner]

need to see the solution and some sample data.
The output doesn't show enough info

[grahamg]

Will email solution.

Thanks

Recently I've begun getting erratic error messages with zero content. Probing with the debugger I've discovered:

Code: Select all

globals.gint1 = 1;

generates

java.lang.NullPointerException

where globals.gint1 is an integer global.

This didn't make much sense, so I relaunched, I removed the filter from the form, tested for a transaction. I moved the instruction to a test method attached to a completely different form and set a string of setting of the global to different numbers.

Now, get this, when I changed the form being currently displayed, the test method worked, the global could be set. Redisplay the form and the global returns an error -- even though the test method is not attached to that form. The one common factor is the current display of this particular form.

This still doesn't make much sense. What characteristic of this form could account for causing this fault to the global integer field? I'm looking for recommendations on how to proceed from here.

Hello guys,

Just found a small irregular in the method editor.

When setting the "setSelectedIndex" property from the tree it places a space in front of the "foundset" property

Code: Select all

forms.Contact_Details. foundset.setSelectedIndex(index)

Code still works however.

When using CTRL + Space the code is correct

Code: Select all

forms.Contact_Details.foundset.setSelectedIndex(index)

Recently I've begun getting erratic error messages with zero content. Probing with the debugger I've discovered...

Can you sent us the .log.txt as found in your Servoy install dir when this happens?

[Jan Blok]

...Just found a small irregular in the method editor...

Corrected in next release

[Jan Blok]

...When opening a client I get the following Java webstart error...

Are you sure you did update the server correctly? can you for example start a client from http://demo.servoy.com:8080/index.html ?

[jcompagner]

are you absoluutly sure that you start the server where you connect to with the client with java 1.4 and not java 1.5??
Because that really looks like a client and server are both in 1.5. This is a know bug and i will try to fix it for the next release. Or disabled the fast loading feature for now.

You can see what youre server uses by going to the /servoy-admin/ page

Hello Jan,

Are you sure you did update the server correctly? can you for example start a client from http://demo.servoy.com:8080/index.html ?

I can download the file completely but I can`t get connection to the repository. (this has probably something to do with our proxyserver)

I can demonstrate it tomorrow to one of you on the servoy seminar.
