Hi all,

We have been trying to upgrade our ZK version from maven by updating our pom.xml. However upon starting the project we see that the most user interfaces that we have build are functioning correctly.

However, upon using the the paging for our listbox:

<n:footer class="main-footer"> 
<paging onPaging="@command('onPaging', activePage=event.activePage)" pageSize="@load(vm.pageSize)"
            totalSize="@load(vm.totalSize)" activePage="@bind(vm.activePage)" sclass="floatright" pageIncrement="1" detailed="false"></paging>
</n:footer>

We encounter two errors (8901/dev/zkau/web/_zv2021032310/js/zul.inp.wpd:19):

Uncaught TypeError: Cannot read property 'value' of undefined

 bind_: function() {
                    this.$supers(g, "bind_", arguments);
                    var a = this.getInputNode();
                    this._lastChg = this._defRawVal = a.value;
                    this.domListen_(a, "onFocus", "doFocus_").domListen_(a, "onBlur", "doBlur_").domListen_(a, "onSelect").domListen_(a, "onMouseOver").domListen_(a, "onMouseOut");
                    if (zk.ie10_ || zk.ie11_) {
                        var b = this;
                        setTimeout(function() {
                            b.domListen_(a, "onInput", "doInput_")
                        }, 100)
                    } else
                        this.domListen_(a, "onInput", "doInput_");
                    zk.ios && this.domListen_(a, "onTouchStart", "_doTouch");
                    if (a = a.form)
                        jq(a).on("reset", this.proxy(this._resetForm));
                    zWatch.listen({
                        onShow: this
                    })

The above line (this.lastChg = this.defRawVal = a.value;) The value this._defRawVal is undefined.

And on line (zul.inp.wpd:formatted:460):

Uncaught (in promise) TypeError: Cannot read property 'form' of undefined

 unbind_: function() {
                    zWatch.unlisten({
                        onShow: this
                    });
                    this.$class._stopOnChanging(this);
                    this.clearErrorMessage(!0);
                    var a = this.getInputNode();
                    this.domUnlisten_(a, "onFocus", "doFocus_").domUnlisten_(a, "onBlur", "doBlur_").domUnlisten_(a, "onSelect").domUnlisten_(a, "onMouseOver").domUnlisten_(a, "onMouseOut").domUnlisten_(a, "onInput", "doInput_");
                    zk.ios && this.domUnlisten_(a, "onTouchStart", "_doTouch");
                    (a = a.form) && jq(a).off("reset", this.proxy(this._resetForm));
                    this.$supers(g, "unbind_", arguments)
                },

Here a.form = null.

How can we solve these errors?

Here is a small video in which i recorded the actions: link video

Kind regards,

Remie

Hi Remie,

9.5.1 stable releases are already available for PE / EE download. This fix will be available in all releases after that. I believe next CE release including this fix will be 9.6.0 CE

Hi MDuchemin, thanks for your information. I will wait for the 9.6.0 CE version to be released.

Hi MDuchemin,

You are completely right! I have switched to version 9.5.1(-Eval) and paging just works fine without any errors. My next question is, when will this fix be pushed to a new stable release? That way i can use that version that is compatible.

Kind regards,

Remie

Hi rmalik,

The most likely cause is that in recent version, the listbox will perform partial invalidation instead of redrawing its full content under some scenarios.

This is more efficient from a network and rendering pov, but it has caused issues in similar structures as yours (component to update located in the headers). See ticket here: https://tracker.zkoss.org/browse/ZK-4709

Could you test out the 9.5.1(-Eval) release and check if this issue still happens after the bug fix has been applied?

Upon further investigation its the combination of the auxheader and datebox causing this issue. After removing:

<auxheader><datebox width="100%" value="@bind(filtervm.field('ReceiptDate').value)" format="dd-MM-yy"  /></auxheader></template>

Paging works correctly without errors. Is something changed for the datebox when using it in auxheaders zk 9.5.0.3?
