Hi,

I’m trying to get the javascript debugger working, but it doesn’t seem to work well.

I’m using a combination of html, css and javascript (currently merely testing, so I could send the code if necessary). Here’s some code that causes the debugger to behave strangely (just for reference, I added the line numbers):

19 function parseJSONTree(){
20 var id=””;
21 var name=””;
22 var jsonTxt=this.req.responseText;
23 var jsonObj=eval(‘(‘+jsonTxt+’)’);
24 var locations=jsonObj.locations
25
26 var infoPanel = document.getElementById(‘locations’);
27 var locationTree = new tree.Tree();
28 locationTree.fill(jsonObj, ‘locations’);
29
30 locationTree.display(infoPanel);
31
32 showLocations(locations, 0);
33 }

When I start debugging the initial html file, the debugger correctly stops at the first breakpoint.

if this breakpoint is set at line 20 : then I can successfully use the step over button, it proceeds to the next line, and the variables view correctly shows the modified values of variables id and name.
In line 22, a json text file is read into memory. This is located in the same directory as the html and js files.
But at line 23, the debugger stops to work. The step into, step over, and resume buttons are being disabled (grey buttons, can’t click them anymore).

If I set the first breakpoint at line 30 (as an example), the variables id and name are correctly shown in the variables view, but any variable that has been defined after line 23 is shown as ‘undefined’, although the script runs when not in debug mode.
From that point on, the step into and step over buttons don’t work anymore. Step into just moves to the next line, without performing the code in the function.

Here’s the stack :

parseJSONTree() DataJSONTree.js [Line: 30]
parseJSONTree() DataJSONTree.js [Line: 23]
call() [built-in] [Line: 1]
anonymous() net.js [Line: 59]
call() [built-in] [Line: 1]
anonymous() net.js [Line: 40]

In the error log, I found the following :

!ENTRY org.eclipse.core.runtime 4 2 2005-12-25 11:25:12.282
!MESSAGE An internal error occurred during: “Fetching children from debug target”.

Hope this gives you enough information. I’m looking forward to a solution, as I think the js debugger could be a tremendous help for my developments.
Thanks,

Bartlebooth

I found this in the error log, but it’s probably not related to the phenomenon that I am describing here. But for your information :
