Problems using DynamicInstallerRequirementValidator (izpack 5.0.7)

[Oliver Kersten]

Hello,

I want to check the installed program version during installation. I don't know if it's the right way, but I have tried to use the DynamicInstallerRequirementValidator.

Defining the "dynamicinstallerrequirements"

  ....
  <dynamicinstallerrequirements>

<installerrequirement severity="ERROR" condition="isValidVersion" messageid="error.wrongProgramVersion" />

  </dynamicinstallerrequirements>
  ....

 leads me to this error

[izpack] ERROR:  'cvc-complex-type.3.2.2: Attribut "severity" darf nicht in Element "installerrequirement" vorkommen.'

   [izpack] ERROR:  'com.sun.org.apache.xml.internal.utils.WrappedRuntimeException: cvc-complex-type.3.2.2: Attribut "severity" darf nicht in Element "installerrequirement" vorkommen.'

severity seems to be a wrong attribute.
I have checked the "izpack-installation-5.0.xsd" schema. But following the schema:

<xs:complexType name="dynamicInstallerRequirementsType">

        <xs:sequence>

            <xs:element name="installerrequirement" minOccurs="0" maxOccurs="unbounded">

                <xs:complexType>

                    <xs:attribute name="status" use="required">

                        <xs:simpleType>

                            <xs:restriction base="xs:string">

                                <xs:enumeration value="warning"/>

                                <xs:enumeration value="error"/>

                            </xs:restriction>

                        </xs:simpleType>

                    </xs:attribute>

                    <xs:attribute name="condition" type="xs:string" use="required"/>

                    <xs:attribute name="messageid" type="xs:string" use="required"/>

                </xs:complexType>

            </xs:element>

        </xs:sequence>

    </xs:complexType>

ends in another error:

  <dynamicinstallerrequirements>

<installerrequirement status="error" condition="isValidApenioVersion" messageid="error.wrongProgramVersion" />

  </dynamicinstallerrequirements>

Now severity is required again. I am a little bit confused.

And another Problem is, that the compiler can't find the class. I followed the documentation:

<panels>

    <panel classname="TargetPanel"/>

    <panel classname="PacksPanel">

    <validator classname="DynamicInstallerRequirementValidator"/>

    </panel>

    <panel classname="InstallPanel"/>

    <panel classname="FinishPanel"/>

  </panels>

and got this error:

Adding panel: TargetPanel_0 :: Classname : com.izforge.izpack.panels.target.TargetPanel

Can anyone help me?

thanks, Oliver

Hello,

now I have found the open bug report "DynamicInstallerRequirements are broken" : https://izpack.atlassian.net/browse/IZPACK-986.

It's about two years old. Is there any workarround. Can I use an other validator. I'm stuck here.

ciao, Oliver

Hi Oliver, I will check this soon.
