UndefinedObject does not understand bMajorHashManual

[Ralf]

Hello All,

first, this Forum is a nice idea, thanks.

Now my problem, the title is the error message too. Several customers become this error on several machines, not on all. But, i can't find any error in installation. And at me it works fine. Anyone any idea whats wrong?

Many thanks

Ralf

Why not look at method "majorHashStyle" and look for the senders of bMajorHashManual and then you know, which object is nil ... and perhaps
this will give you a hint.

so far so good. The problem is, the bMajorhashStyle will not initialized, but i don't know why. For me, it looks like good, and it's not possible to debug at the customer. I have hope, anyone has the same problem and know what I must do to solve it.

Ralf:

This looks like it is a part of WidgetKit/BusinessGraphics. Have you checked to make sure the DLL is present and on the user's path? Is the library open?

ok, I will test it. Thanks:-)

so, I have found a part of the problem, but it is not solved.
here the way I have found, i'm not sure where the problem is

the error come from here:

WkAxisGrids>>majorHashStyle

"Answer the major hash style. Valid values are
0 noGrids
1 normal grid lines
2 'inner' ticks only
3 'outer' ticks only
4 'spanner' (inner and outer) ticks only
5 grids with outer ticks (extended grids
-1 use automatic settings (valid for X, Y1 and Y2 axis only)"

self isIndependentAxis
ifTrue: [^info nMajorHashStyle].
^info bMajorHashManual asBoolean
ifTrue: [info nMajorHashStyle] "info is nil! how?"
ifFalse: [-1]

info will not initialized

WkAxisGrids>>getInfo


"Private -
Get the attributes of the axis grid lines.
If the attributes cannot be located in the graph, return nil."

| result class ptr axis|
class := self isIndependentAxis
ifTrue: [WkGridLinesOrdInfo]
ifFalse: [WkGridLinesInfo].
axis := class new.
result := GetGraphAttr
callWith: (graphContext asParameter ifNil: [^nil]) "asParameter will return nil, how?"
with: GraphLayer
with: O5dBackground
with: NullSeriesid
with: NullGroupid
with: self gridCode
with: (ptr := axis asPointer) asAddressParameter.
"info will never set"
info := class fromPointer: ptr.
ptr free.
^result == 1
ifTrue: [info]
ifFalse: [nil]

an now look here

WkGraphContext>>initialize
"Private"

super initialize.
autoSizeFonts := false.
[gpGraph := AllocGraphPtr call]
when: ExError
do: [:sig |
gpGraph := nil.
sig exitWith: nil].
gpGraph isNil ifTrue: [^self].
areaElement := WkAreaElement on: self.
textElement := WkTextElement on: self.
lineElement := WkLineElement on: self.
[self initDataCallbacks.
self loadDefaultTemplate "throws an exception: general protection fault, i don't no!"]
when: ExError
do: [:sig |
gpGraph := nil. "in error block the value becomes nil "
sig exitWith: nil]

WkGraphContext>>loadDefaultTemplate

"Private: Load the default template file which contains a sample look
with no data."

(self templateFileExists: self defaultTdcFile) "the file will not found, no path, nothing, only a filename!"
ifTrue: [self basicReadFrom: self defaultTdcFile]
ifFalse: [self fromBytes: self defaultGraphContextStructure]. "this will cause the error, an general protection fault"
self
subTitle: 'Instantiations, Inc., Smalltalk Systems Division';
footnote: 'Portland, Oregon'.

the behavior is not ever so, but many times. Is it possible, that the dll has an error or after a time the dll is wrong or is a part of memory for the dll is override with wrong code?

[solveig]

Ralf:

The tdc file is used as a template for initializing attributes of a generic graph.

It must be in the working directory (e.g. image700). It's name should be 'default.tdc' If it is not, you will get a walkback like the one you posted.

I got this error yesterday after installing JWARS at *&%#&#@ for a training class. I created a student user in XP, and got this error when trying to run the simulation. The solution was to make the student user a member of the Power Users group in XP. The account evidently did not have enough permissions as a regular user.
